Introduction e name of Bulsu-san (BSS) originated from its therapeutic effects that help to promote easy labor as if being touched by merciful Buddha’s hand [1]. BSS is composed of Angelicae Sinensis Radix (Danggui, DG) and Cnidium officinale Makino (Cheongung, CG), which is one of the most commonly used herb pairs in Traditional Medicine of East Asia and the usual component ratio is 2 : 3 (CG : DG) or 1 : 1 [2]. BSS is widely used in women’s medicine in East Asia; its recognized therapeutic effects are as follows: removal of impure blood, blood making, easy parturition, acceleration of labor, elimination of dead fetus or placenta, amelioration of pain, nourishing blood, and promoting blood circulation [3]. What is more, recent experimental research on the CG- DG herb pair indicated that they affect the nourishment of blood [4], activate blood circulation, and prevent blood stasis [5]. In addition, the CG-DG herb pair showed significant inhibitory effects on the proliferation and protein synthesis of vascular smooth muscle cells [6]. It was suggested BSS could affect the activities of Akt kinase and eNOS by increasing intracellular Ca 2+ and reducing ROS levels [7] and regulate menstruation and provide relief from pain by enabling the management of uterine smooth muscle contractions [8]. Although BSS has therapeutic effects on various pathological symptoms in pregnant or childbearing aged women, this research focused on the molecular mechanisms and impact of BSS on easing parturition and the acceleration of labor. In terms of parturition onset, numerous studies have described the complex hormone interactions between estro- gen, progesterone, oxytocin, corticosteroid, and prostaglan- din. Among these, corticotrophin releasing hormone (CRH) is regarded as a trigger that initiates the labor [9]. e placenta releases substantial amounts of CRH, which stimulates the pituitary glands of both mother and fetus to secrete adreno- corticotropin hormone [10]. is in turn induces the release of estrogen precursor, which is converted into estrogen by the placenta that induces smooth muscle contraction [10]. Additionally, dilatation of cervical connective tissue and smooth muscle is induced by the following changes: a shiſt from progesterone to estrogen dominance, increased respon- siveness to oxytocin via the upregulation of myometrial oxy- tocin receptor, increased prostaglandins synthesis in uterus, increased myometrial gap junction formation, decreased nitric oxide activity, and increased influx of calcium into myocyte [11].

1 Introduction

The name of Bulsu-san (BSS) originated from its therapeuticeffects that help to promote easy labor as if being touchedby merciful Buddharsquos hand [1] BSS is composed of AngelicaeSinensisRadix (Danggui DG) andCnidium officinaleMakino(Cheongung CG) which is one of the most commonlyused herb pairs in Traditional Medicine of East Asia andthe usual component ratio is 2 3 (CG DG) or 1 1 [2]BSS is widely used in womenrsquos medicine in East Asia itsrecognized therapeutic effects are as follows removal ofimpure blood blood making easy parturition accelerationof labor elimination of dead fetus or placenta amelioration ofpain nourishing blood and promoting blood circulation [3]

What is more recent experimental research on the CG-DG herb pair indicated that they affect the nourishment ofblood [4] activate blood circulation and prevent blood stasis[5] In addition the CG-DG herb pair showed significantinhibitory effects on the proliferation and protein synthesis ofvascular smooth muscle cells [6] It was suggested BSS couldaffect the activities of Akt kinase and eNOS by increasingintracellular Ca2+ and reducing ROS levels [7] and regulatemenstruation and provide relief from pain by enabling the

management of uterine smooth muscle contractions [8]Although BSS has therapeutic effects on various pathologicalsymptoms in pregnant or childbearing aged women thisresearch focused on the molecular mechanisms and impactof BSS on easing parturition and the acceleration of labor

In terms of parturition onset numerous studies havedescribed the complex hormone interactions between estro-gen progesterone oxytocin corticosteroid and prostaglan-din Among these corticotrophin releasing hormone (CRH)is regarded as a trigger that initiates the labor [9]Theplacentareleases substantial amounts of CRH which stimulates thepituitary glands of both mother and fetus to secrete adreno-corticotropin hormone [10] This in turn induces the releaseof estrogen precursor which is converted into estrogen bythe placenta that induces smooth muscle contraction [10]Additionally dilatation of cervical connective tissue andsmooth muscle is induced by the following changes a shiftfrom progesterone to estrogen dominance increased respon-siveness to oxytocin via the upregulation of myometrial oxy-tocin receptor increased prostaglandins synthesis in uterusincreased myometrial gap junction formation decreasednitric oxide activity and increased influx of calcium intomyocyte [11]

Figure 1 The workflow the network pharmacological approach of Bulsu-san (BSS) namely active compounds screening target fishingnetwork analysis and relevant organ location mapping was performed in this study

The hypothesis of this study was that BSS may promotethe positive-feedback of hormone loops as well as a seriesof myometrial and cervical changes to ease parturition andsafely accelerate labor A network based in silico approachwas used to identify the effect of BSS on parturition relatedsystems and the aim of this study was to elucidate the effect ofBSS on the parturition by system-level analysisTheworkflowof the network pharmacological study is summarized inFigure 1

2 Material and Methods

21 Identification of Active Compounds Compounds in CGand DG were identified using a phytochemical databasethat is the Traditional Chinese Medicine Systems Phar-macology (TCMSP httpibtshkbueduhkLSPtcmspphp)We applied parameters related to absorption distributionmetabolism and excretion (ADME) namely human drug-likeness (DL) [12] oral bioavailability (OB) [13] and Caco-2 permeability (Caco-2) to screen the Potential active com-pounds in BSS [14]

211 Drug-Likeness Evaluation DL helps filter ldquodrug-likerdquocompounds in oriental herbs as DL represents a qualitativeconcept for valuations based on how ldquodrug-likerdquo a prospec-tive compound is [15] Accordingly a high DL may lead toa greater possibility of therapeutic success and compoundswith a higher DL value are more likely to possess certainbiological properties [16] The calculations of DL in TCMSP

database were based on Tanimoto coefficient formula [17] asfollows

119865 (119860 119861) =119860 times 119861

1198602 + 1198612 minus 119860 times 119861 (1)

where 119860 represents the molecular parameters of herbal com-pounds and119861 is the averagemolecular parameters of all com-pounds in theDrugbank database (httpwwwdrugbankca)[18] In the present study we excluded compounds with a DLof lt008 Other previous researches of herbal formulas set ahigher threshold in the range of 01 to 018However we foundout that most compounds of DG have low DL In detail only36 compounds of 125 in DG show higher or equal DL valuethan 008 For this reason this study sets a lower threshold ofDL than other previous researches to see the most potentialtargets of BSS

212 Oral Bioavailability (OB) Prediction OB is defined asthe ratio of active compoundsrsquo absorption into the systemiccirculation which represents the convergence of the ADMEprocess [13] OB values are dependent on drug dissolution inthe gastrointestinal (GI) tract and hepatic and intestinal first-pass metabolism as well as on intestinal membrane perme-ation whichmakes it a major pharmacokinetic parameter fordrug evaluations [16] In this study the OB threshold was setas ge15

213 Caco-2 Permeability Screening Caco-2 permeability isused to predict the absorption of an orally administered

Evidence-Based Complementary and Alternative Medicine 3

drug [14] Surface absorptivity of the small intestine ismaximized with the presence of villi and microvilli for thisreason most orally administered drug absorption occurs inthe small intestine [19] Moreover the movement of orallyadministered drugs across the intestinal epithelial barrierdetermines the rate and extent of human absorption andultimately affects drug bioavailability [20] In the presentstudy compounds with OB DL and Caco-2 values of greaterthan 15 008 and gtminus04 respectively were regarded asactive compounds and subjected to further analysis

214 Lipinskirsquos Rule (LR) Screening In addition the screen-ing standard used was defined based on Lipinskirsquos rule (LR)which identifies druggable compounds as having molecularweight (MW)ofle500Da (MWle 500) chemical compositionwith le5 hydrogen-bond donors le10 hydrogen-bond accep-tors and an octanol-water partition coefficient AlogP of le5 [21] AlogP can be used to estimate local hydrophobicityto produce molecular hydrophobicity maps and to evaluatehydrophobic interactions in protein-ligand complexes [22]Hdon and Hacc are the number of possible hydrogen-bonddonors and acceptors and the hydrogen-bonding capacity ofa drug solute is recognized as a crucial determinant of perme-ability moreover high hydrogen-bonding potential is oftenrelated to lowpermeability and absorption [23] Eventually inthe present studywe selected active compounds satisfying thefollowing criteria OB ge 15 DL ge 008 Caco-2 ge minus04 MWle 500 H-bond donors le 5 H-bond acceptors le 10 AlogP le 5

22 Target Fishing Aside from filtering active compoundswe also sought to identify the molecular targets of theseactive compounds Compound-target interaction profileswere established based on a systematic prediction of mul-tiple drug-target interactions tool which employs randomforest (RF) and support vector machine (SVM) methodsand integrates chemical genomic and pharmacologicalinformation for drug targeting and discovery on a largescale [24] Compound-target interactions satisfying SVMscore ge 08 and RF score ge 07 were selected for furtherstudy Additionally filtered compound-target interactionprofile mapping was performed using the UniProt database(httpwwwuniprotorg) [25]

23 Gene Ontology (GO) Analysis Biological process (BP)of gene ontology (GO) analysis was employed to determinethe biological properties of target genes [26] GO annotationindicates the possibility of direct statistical analysis on genefunction information In this research GO BP terms with119875 values lt 001 were employed and the data was collectedusing the DAVID 68 Gene Functional Classification Tool(httpdavidabccncifcrfgov)

24 Network Construction and Analysis In order to under-stand the multiscale interactions between the active com-pounds of BSS and targets two types of networks werebuilt (1) the herb-compound-target network (H-C-T net-work) in which nodes represent either compounds tar-get genes or herbs and edges indicate herb-compound-target connections and (2) the target-pathway network (T-P

network) to extract the pathways from KEGG database(httpwwwgenomejpkegg) and the terms highly associ-ated with parturition with 119875 values lt 005 were selected asthe related pathways of targets in this work Related targetswere mapped onto relevant pathways which resulted in theT-P network Both networks were generated in Cytoscape351 an open-source biological network visualization anddata integration software package [27]

25 Target Organ Location Map Tissue-specific patterns ofmRNA expression can indicate important associations withbiological events or gene functions [28] To explore thebeneficial effects of BSS during parturition it is importantthat the tissue mRNA expression profiles of target genesat the organ level be known [29] The target organ loca-tion map was built according to the Dataset GeneAtlasU133A gcrma (httpbiogpsorg) BioGPS database providesexpression data acquired by direct measurements of geneexpression obtained by microarrays analysis [30] First themRNA expression patterns of each target gene in 176 partsof organ tissues were obtained Second average values werecalculated for each gene Third frequency of above averagemRNA expression tissue organs was inspected Forth basedon the result from the third step and parturition mechanismtheory mRNA expression data of relevant organ tissueswere extracted and categorized into 6 groups namely uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smooth muscle and whole blood

3 Results

31 Identification of Active Compounds 314 compounds ofBSSwere identified including 189molecules in CG and 125 inDG (as shown in Supplementary Material Table S1 in Supple-mentary Material available online at httpsdoiorg10115520177236436) and active compounds met the criteria OBge 15 Caco-2 ge minus04 and DL ge 008 as well as thestandards of Lipinskirsquos rule (LR) (as shown in Table 1) Indetail 60 active compounds were initially chosen but 8 com-pounds were present in both herbs namely 3-butylidene-7-hydroxyphthalide adenine BdPh beta-selinene palmiticacid senkyunolide-C senkyunolide-D and senkyunolide-E and 14 had no target protein information and werethus excluded from the list of active compounds whereas27 compounds with lower ADME properties than abovethresholds were included which were reported to be relatedto oxytocin In total 65 active compounds were filtered

Although ligustilide and ferulic acid have a DL of lt008both were included in this study Since ligustilide (C12 DL =007 OB = 5372 Caco-2 = 13) was reported to be the maincompound of DG in uterine contraction [31] and ferulic acid(C42DL=006OB=5497 Caco-2= 053) has been reportedto be useful for the treatment of vascular diseases [6 32] andblood deficiency syndrome [33] in China and to suppressinflammatory responses and tumor progression [34] Someother compounds also have been shown experimentally tohave various biological activities for example crysophanol(C42 DL = 021 OB = 1864 Caco-2 = 062) can be usedto treat menorrhagia and thrombocytopenia [35] Perlolyrine

32 Target Fishing The 65 active compounds interact with185 target proteins as shown in Table 2 in other wordson average each compound on average interacts with 285target proteinsThis result confirms the polypharmacologicalcharacter of oriental medicine and demonstrates the syn-ergistic effects of multiple compounds on multiple targets[38] Different compounds in CG and DG can directly affectcommon targets for example the target protein ldquocalmodulin(CALM1)rdquo interacts with crysophanol fromCG and coniferylferulate from DG at the same time which implies thesynergetic or cumulative effects of herbal medicine

33 GO Analysis 397 biological process terms with 119875 valuesof lt001 were sorted using the functional annotation chart ofthe DAVID 68 Gene Functional Classification Tool basedon 185 filtered target genes and 119875 values were adjustedusing the Benjamini-Hochberg method 30 enriched GO BPterms extracted by 119875 value and gene counts are displayed inFigure 2 It is meaningful that most of the target genes aresignificantly related to the various BP involved in parturitionFor instance 30 extracted GO BP terms include ldquoMAPKsignaling pathwaysrdquo ldquosteroid hormone mediated signalingpathwayrdquo ldquoresponse to glucocorticoidrdquo ldquoresponse to estra-diolrdquo and ldquopositive regulation of ERK1 and ERK2 cascaderdquoldquoMAPK signaling pathwaysrdquo were reported to be activatedin human uterine cervical ripening during parturition [39]ldquoSteroid hormone mediated signaling pathwayrdquo is highly

related to parturition process as estrogen and progesteroneplay important roles in pregnancy and parturition andestrogen induceS the principal stimulatory myometrial con-tractility [40] Also estradiol takes key place in parturitionprocess [41] It was identified that increased ERK activationis observed at the onset of labor and it promotes myometrialcontractility and development of parturition [42 43] To sumup the target genes of BSS are highly associated with thebiological process (BP) of parturition

34 Network Construction and Analysis Network analysis isan efficient tool for visualizing and understanding multipletargeted drug actions and demonstrates drug actions withinthe context of the whole genome [44 45] For a better insightof therapeutic impacts H-C-T and T-P networks were con-structed and displayed in Figures 3 and 4 respectively In theH-C-T network nodes represent herb names compoundsand targets Also in the T-P network circular nodes representtargets and triangle nodes represent pathways Besides nodesize is relative to the degree and edges show interactionsbetween nodes

H-C-T network confirmed that there were 739 interac-tions between 185 targets and 65 active compounds of CGand DG oleic acid (C48 degree = 42) with the highestnumber of interactions with targets followed by succinicacid (C63 degree = 40) and stigmasterol (C62 degree =37) It shows that single molecules target multiple recep-tors [46] Also some compounds from CG and DG werefound to share common targets Likewise prostaglandinGH synthase 2 (PTGS2 degree = 56) displayed the mostaffinitive connections with compounds followed by gamma-aminobutyric acid receptor subunit alpha-1 (GABRA1 degree= 48) prostaglandin GH synthase 1 (PTGS1 degree = 37)

In addition the top 40 pathways were extracted basedon gene counts and 119875 value (lt005) and 119875 value wasadjusted by Benjamini-Hochbergmethod T-P network usingrelevant targets of herbal compounds is demonstrated inFigure 4 There were 485 interactions between the top 40pathways and 135 of 185 target genes ldquoMetabolic pathwaysrdquo(degree = 49) and ldquoneuroactive ligand-receptor interactionpathwayrdquo (degree = 32) had the highest and the secondhighest numbers of connections with the targets followedby ldquocalcium signalingrdquo (degree = 21) ldquocAMP signaling path-wayrdquo (degree = 17) and ldquocGMP PKG signaling pathwayrdquo(degree = 15) These are compelling results that parturitionprocesses are the complex hormone interactions and it iswell known that calcium signals within the myometrium arepivotal for uterine contractions [48] In the same mannersome target genes demonstrated higher degree centralitywith top 40 pathways namely PI3-kinase subunit gamma(PIK3CG degree = 23) cAMP-dependent protein kinase

catalytic subunit alpha (PRKACA degree = 20) proteinkinase C beta type (PRKCB degree = 18) and calmodulin(CALM1 degree = 11) We can confirm the same result in theprevious researches For instance PI3-kinase subunit gammaplays the key role in regulating cAMP calcium cyclingand beta-adrenergic signaling [49] Moreover during thelabor calmodulin-calcium complex activates myosin light-chain kinase which causes the generation of ATPase activityeventually uterine contraction is promoted [50]

H-C-T network explains the multitarget multicom-pounds properties and accumulates effect of herbalmedicines and T-P network shows that target genes of BSSare highly related to the pathway associated with parturi-tion process

35 Target Organ Location Map It is important to confirmthe tissue mRNA expression profiles of the target genes atthe organ level to identify the effects of BSS on parturi-tion Since there was no mRNA expression information inBioGPS of muscarinic acetylcholine receptor M1 (CHRM1)putative beta-glucuronidase-like protein SMA3 (GUSBP1)and retinol-binding protein 2 (RBP2) excluding these 3targets from 185 filtered targets totally 182 genes mRNAexpression profiles were analyzed in this studyTherewere 519interactions between target genes and organ locations Thenetworks of target genes tissuemRNAexpression profiles andcompounds of BSS are shown in Figure 5

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

in all of 6 groups For instance muscarinic acetylcholinereceptor M2 (CHRM2) neuronal acetylcholine receptorsubunit 120572-2 (CHRNA2) gamma-aminobutyric acid receptorsubunit alpha-3 (GABRA3) NO synthase inducible (NOS2)cGMP-inhibited 3101584051015840-cyclic phosphodiesterase A (PDE3A)and sodium-dependent dopamine transporter (SLC6A3)recorded beyond average mRNA expression in all six groupsFurthermore 79 of targets were expressed in two or moreorgan tissues which suggests that those organs and targetgenes of BSS are closely correlated

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

Figure 1 The workflow the network pharmacological approach of Bulsu-san (BSS) namely active compounds screening target fishingnetwork analysis and relevant organ location mapping was performed in this study

The hypothesis of this study was that BSS may promotethe positive-feedback of hormone loops as well as a seriesof myometrial and cervical changes to ease parturition andsafely accelerate labor A network based in silico approachwas used to identify the effect of BSS on parturition relatedsystems and the aim of this study was to elucidate the effect ofBSS on the parturition by system-level analysisTheworkflowof the network pharmacological study is summarized inFigure 1

2 Material and Methods

21 Identification of Active Compounds Compounds in CGand DG were identified using a phytochemical databasethat is the Traditional Chinese Medicine Systems Phar-macology (TCMSP httpibtshkbueduhkLSPtcmspphp)We applied parameters related to absorption distributionmetabolism and excretion (ADME) namely human drug-likeness (DL) [12] oral bioavailability (OB) [13] and Caco-2 permeability (Caco-2) to screen the Potential active com-pounds in BSS [14]

211 Drug-Likeness Evaluation DL helps filter ldquodrug-likerdquocompounds in oriental herbs as DL represents a qualitativeconcept for valuations based on how ldquodrug-likerdquo a prospec-tive compound is [15] Accordingly a high DL may lead toa greater possibility of therapeutic success and compoundswith a higher DL value are more likely to possess certainbiological properties [16] The calculations of DL in TCMSP

database were based on Tanimoto coefficient formula [17] asfollows

119865 (119860 119861) =119860 times 119861

1198602 + 1198612 minus 119860 times 119861 (1)

where 119860 represents the molecular parameters of herbal com-pounds and119861 is the averagemolecular parameters of all com-pounds in theDrugbank database (httpwwwdrugbankca)[18] In the present study we excluded compounds with a DLof lt008 Other previous researches of herbal formulas set ahigher threshold in the range of 01 to 018However we foundout that most compounds of DG have low DL In detail only36 compounds of 125 in DG show higher or equal DL valuethan 008 For this reason this study sets a lower threshold ofDL than other previous researches to see the most potentialtargets of BSS

212 Oral Bioavailability (OB) Prediction OB is defined asthe ratio of active compoundsrsquo absorption into the systemiccirculation which represents the convergence of the ADMEprocess [13] OB values are dependent on drug dissolution inthe gastrointestinal (GI) tract and hepatic and intestinal first-pass metabolism as well as on intestinal membrane perme-ation whichmakes it a major pharmacokinetic parameter fordrug evaluations [16] In this study the OB threshold was setas ge15

213 Caco-2 Permeability Screening Caco-2 permeability isused to predict the absorption of an orally administered

Evidence-Based Complementary and Alternative Medicine 3

drug [14] Surface absorptivity of the small intestine ismaximized with the presence of villi and microvilli for thisreason most orally administered drug absorption occurs inthe small intestine [19] Moreover the movement of orallyadministered drugs across the intestinal epithelial barrierdetermines the rate and extent of human absorption andultimately affects drug bioavailability [20] In the presentstudy compounds with OB DL and Caco-2 values of greaterthan 15 008 and gtminus04 respectively were regarded asactive compounds and subjected to further analysis

214 Lipinskirsquos Rule (LR) Screening In addition the screen-ing standard used was defined based on Lipinskirsquos rule (LR)which identifies druggable compounds as having molecularweight (MW)ofle500Da (MWle 500) chemical compositionwith le5 hydrogen-bond donors le10 hydrogen-bond accep-tors and an octanol-water partition coefficient AlogP of le5 [21] AlogP can be used to estimate local hydrophobicityto produce molecular hydrophobicity maps and to evaluatehydrophobic interactions in protein-ligand complexes [22]Hdon and Hacc are the number of possible hydrogen-bonddonors and acceptors and the hydrogen-bonding capacity ofa drug solute is recognized as a crucial determinant of perme-ability moreover high hydrogen-bonding potential is oftenrelated to lowpermeability and absorption [23] Eventually inthe present studywe selected active compounds satisfying thefollowing criteria OB ge 15 DL ge 008 Caco-2 ge minus04 MWle 500 H-bond donors le 5 H-bond acceptors le 10 AlogP le 5

22 Target Fishing Aside from filtering active compoundswe also sought to identify the molecular targets of theseactive compounds Compound-target interaction profileswere established based on a systematic prediction of mul-tiple drug-target interactions tool which employs randomforest (RF) and support vector machine (SVM) methodsand integrates chemical genomic and pharmacologicalinformation for drug targeting and discovery on a largescale [24] Compound-target interactions satisfying SVMscore ge 08 and RF score ge 07 were selected for furtherstudy Additionally filtered compound-target interactionprofile mapping was performed using the UniProt database(httpwwwuniprotorg) [25]

23 Gene Ontology (GO) Analysis Biological process (BP)of gene ontology (GO) analysis was employed to determinethe biological properties of target genes [26] GO annotationindicates the possibility of direct statistical analysis on genefunction information In this research GO BP terms with119875 values lt 001 were employed and the data was collectedusing the DAVID 68 Gene Functional Classification Tool(httpdavidabccncifcrfgov)

24 Network Construction and Analysis In order to under-stand the multiscale interactions between the active com-pounds of BSS and targets two types of networks werebuilt (1) the herb-compound-target network (H-C-T net-work) in which nodes represent either compounds tar-get genes or herbs and edges indicate herb-compound-target connections and (2) the target-pathway network (T-P

network) to extract the pathways from KEGG database(httpwwwgenomejpkegg) and the terms highly associ-ated with parturition with 119875 values lt 005 were selected asthe related pathways of targets in this work Related targetswere mapped onto relevant pathways which resulted in theT-P network Both networks were generated in Cytoscape351 an open-source biological network visualization anddata integration software package [27]

25 Target Organ Location Map Tissue-specific patterns ofmRNA expression can indicate important associations withbiological events or gene functions [28] To explore thebeneficial effects of BSS during parturition it is importantthat the tissue mRNA expression profiles of target genesat the organ level be known [29] The target organ loca-tion map was built according to the Dataset GeneAtlasU133A gcrma (httpbiogpsorg) BioGPS database providesexpression data acquired by direct measurements of geneexpression obtained by microarrays analysis [30] First themRNA expression patterns of each target gene in 176 partsof organ tissues were obtained Second average values werecalculated for each gene Third frequency of above averagemRNA expression tissue organs was inspected Forth basedon the result from the third step and parturition mechanismtheory mRNA expression data of relevant organ tissueswere extracted and categorized into 6 groups namely uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smooth muscle and whole blood

3 Results

31 Identification of Active Compounds 314 compounds ofBSSwere identified including 189molecules in CG and 125 inDG (as shown in Supplementary Material Table S1 in Supple-mentary Material available online at httpsdoiorg10115520177236436) and active compounds met the criteria OBge 15 Caco-2 ge minus04 and DL ge 008 as well as thestandards of Lipinskirsquos rule (LR) (as shown in Table 1) Indetail 60 active compounds were initially chosen but 8 com-pounds were present in both herbs namely 3-butylidene-7-hydroxyphthalide adenine BdPh beta-selinene palmiticacid senkyunolide-C senkyunolide-D and senkyunolide-E and 14 had no target protein information and werethus excluded from the list of active compounds whereas27 compounds with lower ADME properties than abovethresholds were included which were reported to be relatedto oxytocin In total 65 active compounds were filtered

Although ligustilide and ferulic acid have a DL of lt008both were included in this study Since ligustilide (C12 DL =007 OB = 5372 Caco-2 = 13) was reported to be the maincompound of DG in uterine contraction [31] and ferulic acid(C42DL=006OB=5497 Caco-2= 053) has been reportedto be useful for the treatment of vascular diseases [6 32] andblood deficiency syndrome [33] in China and to suppressinflammatory responses and tumor progression [34] Someother compounds also have been shown experimentally tohave various biological activities for example crysophanol(C42 DL = 021 OB = 1864 Caco-2 = 062) can be usedto treat menorrhagia and thrombocytopenia [35] Perlolyrine

(C52 DL = 027 OB = 6595 Caco-2 = 088) was confirmedto have a protective effect on injured human umbilical veinendothelial cells [36] and myricanone (C48 DL = 051 OB= 5761 Caco-2 = 067) was found to best inhibit mouse skintumor progression [37]

32 Target Fishing The 65 active compounds interact with185 target proteins as shown in Table 2 in other wordson average each compound on average interacts with 285target proteinsThis result confirms the polypharmacologicalcharacter of oriental medicine and demonstrates the syn-ergistic effects of multiple compounds on multiple targets[38] Different compounds in CG and DG can directly affectcommon targets for example the target protein ldquocalmodulin(CALM1)rdquo interacts with crysophanol fromCG and coniferylferulate from DG at the same time which implies thesynergetic or cumulative effects of herbal medicine

33 GO Analysis 397 biological process terms with 119875 valuesof lt001 were sorted using the functional annotation chart ofthe DAVID 68 Gene Functional Classification Tool basedon 185 filtered target genes and 119875 values were adjustedusing the Benjamini-Hochberg method 30 enriched GO BPterms extracted by 119875 value and gene counts are displayed inFigure 2 It is meaningful that most of the target genes aresignificantly related to the various BP involved in parturitionFor instance 30 extracted GO BP terms include ldquoMAPKsignaling pathwaysrdquo ldquosteroid hormone mediated signalingpathwayrdquo ldquoresponse to glucocorticoidrdquo ldquoresponse to estra-diolrdquo and ldquopositive regulation of ERK1 and ERK2 cascaderdquoldquoMAPK signaling pathwaysrdquo were reported to be activatedin human uterine cervical ripening during parturition [39]ldquoSteroid hormone mediated signaling pathwayrdquo is highly

related to parturition process as estrogen and progesteroneplay important roles in pregnancy and parturition andestrogen induceS the principal stimulatory myometrial con-tractility [40] Also estradiol takes key place in parturitionprocess [41] It was identified that increased ERK activationis observed at the onset of labor and it promotes myometrialcontractility and development of parturition [42 43] To sumup the target genes of BSS are highly associated with thebiological process (BP) of parturition

34 Network Construction and Analysis Network analysis isan efficient tool for visualizing and understanding multipletargeted drug actions and demonstrates drug actions withinthe context of the whole genome [44 45] For a better insightof therapeutic impacts H-C-T and T-P networks were con-structed and displayed in Figures 3 and 4 respectively In theH-C-T network nodes represent herb names compoundsand targets Also in the T-P network circular nodes representtargets and triangle nodes represent pathways Besides nodesize is relative to the degree and edges show interactionsbetween nodes

H-C-T network confirmed that there were 739 interac-tions between 185 targets and 65 active compounds of CGand DG oleic acid (C48 degree = 42) with the highestnumber of interactions with targets followed by succinicacid (C63 degree = 40) and stigmasterol (C62 degree =37) It shows that single molecules target multiple recep-tors [46] Also some compounds from CG and DG werefound to share common targets Likewise prostaglandinGH synthase 2 (PTGS2 degree = 56) displayed the mostaffinitive connections with compounds followed by gamma-aminobutyric acid receptor subunit alpha-1 (GABRA1 degree= 48) prostaglandin GH synthase 1 (PTGS1 degree = 37)

and muscarinic acetylcholine receptor M1 (CHRM1 degree= 37) Except for C60 (PLA2G1B degree = 1) the rest ofthe 64 active compounds are connected with more thanone target likewise 73 (395) target genes out of 185interactedwithmore than one compoundThis result demon-strates the multicompounds and multitarget properties ofherbal compounds and there was a report that compoundswith multiple targets could have greater therapeutic efficacy[47]

In addition the top 40 pathways were extracted basedon gene counts and 119875 value (lt005) and 119875 value wasadjusted by Benjamini-Hochbergmethod T-P network usingrelevant targets of herbal compounds is demonstrated inFigure 4 There were 485 interactions between the top 40pathways and 135 of 185 target genes ldquoMetabolic pathwaysrdquo(degree = 49) and ldquoneuroactive ligand-receptor interactionpathwayrdquo (degree = 32) had the highest and the secondhighest numbers of connections with the targets followedby ldquocalcium signalingrdquo (degree = 21) ldquocAMP signaling path-wayrdquo (degree = 17) and ldquocGMP PKG signaling pathwayrdquo(degree = 15) These are compelling results that parturitionprocesses are the complex hormone interactions and it iswell known that calcium signals within the myometrium arepivotal for uterine contractions [48] In the same mannersome target genes demonstrated higher degree centralitywith top 40 pathways namely PI3-kinase subunit gamma(PIK3CG degree = 23) cAMP-dependent protein kinase

catalytic subunit alpha (PRKACA degree = 20) proteinkinase C beta type (PRKCB degree = 18) and calmodulin(CALM1 degree = 11) We can confirm the same result in theprevious researches For instance PI3-kinase subunit gammaplays the key role in regulating cAMP calcium cyclingand beta-adrenergic signaling [49] Moreover during thelabor calmodulin-calcium complex activates myosin light-chain kinase which causes the generation of ATPase activityeventually uterine contraction is promoted [50]

H-C-T network explains the multitarget multicom-pounds properties and accumulates effect of herbalmedicines and T-P network shows that target genes of BSSare highly related to the pathway associated with parturi-tion process

35 Target Organ Location Map It is important to confirmthe tissue mRNA expression profiles of the target genes atthe organ level to identify the effects of BSS on parturi-tion Since there was no mRNA expression information inBioGPS of muscarinic acetylcholine receptor M1 (CHRM1)putative beta-glucuronidase-like protein SMA3 (GUSBP1)and retinol-binding protein 2 (RBP2) excluding these 3targets from 185 filtered targets totally 182 genes mRNAexpression profiles were analyzed in this studyTherewere 519interactions between target genes and organ locations Thenetworks of target genes tissuemRNAexpression profiles andcompounds of BSS are shown in Figure 5

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

water soluble polysaccharide but coumarin which is liposol-uble including nodakenin (1) peucedanone (2) marmesin(3) decursinol (4) 7-hydroxy-6-(2R-hydroxy-3-methylbut-3-enyl) coumarin (5) demethylsuberosin (6) decursin (7)decursinol angelate (8) and isoimperatorin (9) [56] Ofthese decursin and its isomer decursinol angelate have beenreported to be the active compounds in AGR [57] It wasidentified in the experimental studies that AGR and DGact via different mechanisms in the cardiovascular centralnervous system and anticancer activity but both have similarpharmacological effects [57] Since the compositions of DGand AGR differ further study on BSS with AGR is requiredCurrently BSS is commonly prescribed to treat cerebravascular and cardiovascular diseases in China [33] but inKorea BSS is widely applied in obstetrics

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

Figure 5 Target organ location map it shows that tissue-specific patterns of mRNA expression are highly active in relative organs ofparturition process such as uterus fetus placenta hypothalamus pituitary and smooth muscle Yellow nodes show compounds and pinknodes indicate targets and node size is relative to the degree and edges demonstrate interactions between nodes

related organ tissues such as those of the uterus placentafetus hypothalamus and pituitary gland

This study employed the network analytical methodsto show the multicompound multitarget properties of BSSThe results not only support clinical applications of BSS oneasing childbirth but also suggest the related target genes andpathways of BSS on promoting parturition according to asystems-level in silico analytic approach However detailedmechanisms and other functions of BSS should be discussedfurther

drug [14] Surface absorptivity of the small intestine ismaximized with the presence of villi and microvilli for thisreason most orally administered drug absorption occurs inthe small intestine [19] Moreover the movement of orallyadministered drugs across the intestinal epithelial barrierdetermines the rate and extent of human absorption andultimately affects drug bioavailability [20] In the presentstudy compounds with OB DL and Caco-2 values of greaterthan 15 008 and gtminus04 respectively were regarded asactive compounds and subjected to further analysis

214 Lipinskirsquos Rule (LR) Screening In addition the screen-ing standard used was defined based on Lipinskirsquos rule (LR)which identifies druggable compounds as having molecularweight (MW)ofle500Da (MWle 500) chemical compositionwith le5 hydrogen-bond donors le10 hydrogen-bond accep-tors and an octanol-water partition coefficient AlogP of le5 [21] AlogP can be used to estimate local hydrophobicityto produce molecular hydrophobicity maps and to evaluatehydrophobic interactions in protein-ligand complexes [22]Hdon and Hacc are the number of possible hydrogen-bonddonors and acceptors and the hydrogen-bonding capacity ofa drug solute is recognized as a crucial determinant of perme-ability moreover high hydrogen-bonding potential is oftenrelated to lowpermeability and absorption [23] Eventually inthe present studywe selected active compounds satisfying thefollowing criteria OB ge 15 DL ge 008 Caco-2 ge minus04 MWle 500 H-bond donors le 5 H-bond acceptors le 10 AlogP le 5

22 Target Fishing Aside from filtering active compoundswe also sought to identify the molecular targets of theseactive compounds Compound-target interaction profileswere established based on a systematic prediction of mul-tiple drug-target interactions tool which employs randomforest (RF) and support vector machine (SVM) methodsand integrates chemical genomic and pharmacologicalinformation for drug targeting and discovery on a largescale [24] Compound-target interactions satisfying SVMscore ge 08 and RF score ge 07 were selected for furtherstudy Additionally filtered compound-target interactionprofile mapping was performed using the UniProt database(httpwwwuniprotorg) [25]

23 Gene Ontology (GO) Analysis Biological process (BP)of gene ontology (GO) analysis was employed to determinethe biological properties of target genes [26] GO annotationindicates the possibility of direct statistical analysis on genefunction information In this research GO BP terms with119875 values lt 001 were employed and the data was collectedusing the DAVID 68 Gene Functional Classification Tool(httpdavidabccncifcrfgov)

24 Network Construction and Analysis In order to under-stand the multiscale interactions between the active com-pounds of BSS and targets two types of networks werebuilt (1) the herb-compound-target network (H-C-T net-work) in which nodes represent either compounds tar-get genes or herbs and edges indicate herb-compound-target connections and (2) the target-pathway network (T-P

network) to extract the pathways from KEGG database(httpwwwgenomejpkegg) and the terms highly associ-ated with parturition with 119875 values lt 005 were selected asthe related pathways of targets in this work Related targetswere mapped onto relevant pathways which resulted in theT-P network Both networks were generated in Cytoscape351 an open-source biological network visualization anddata integration software package [27]

25 Target Organ Location Map Tissue-specific patterns ofmRNA expression can indicate important associations withbiological events or gene functions [28] To explore thebeneficial effects of BSS during parturition it is importantthat the tissue mRNA expression profiles of target genesat the organ level be known [29] The target organ loca-tion map was built according to the Dataset GeneAtlasU133A gcrma (httpbiogpsorg) BioGPS database providesexpression data acquired by direct measurements of geneexpression obtained by microarrays analysis [30] First themRNA expression patterns of each target gene in 176 partsof organ tissues were obtained Second average values werecalculated for each gene Third frequency of above averagemRNA expression tissue organs was inspected Forth basedon the result from the third step and parturition mechanismtheory mRNA expression data of relevant organ tissueswere extracted and categorized into 6 groups namely uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smooth muscle and whole blood

3 Results

31 Identification of Active Compounds 314 compounds ofBSSwere identified including 189molecules in CG and 125 inDG (as shown in Supplementary Material Table S1 in Supple-mentary Material available online at httpsdoiorg10115520177236436) and active compounds met the criteria OBge 15 Caco-2 ge minus04 and DL ge 008 as well as thestandards of Lipinskirsquos rule (LR) (as shown in Table 1) Indetail 60 active compounds were initially chosen but 8 com-pounds were present in both herbs namely 3-butylidene-7-hydroxyphthalide adenine BdPh beta-selinene palmiticacid senkyunolide-C senkyunolide-D and senkyunolide-E and 14 had no target protein information and werethus excluded from the list of active compounds whereas27 compounds with lower ADME properties than abovethresholds were included which were reported to be relatedto oxytocin In total 65 active compounds were filtered

Although ligustilide and ferulic acid have a DL of lt008both were included in this study Since ligustilide (C12 DL =007 OB = 5372 Caco-2 = 13) was reported to be the maincompound of DG in uterine contraction [31] and ferulic acid(C42DL=006OB=5497 Caco-2= 053) has been reportedto be useful for the treatment of vascular diseases [6 32] andblood deficiency syndrome [33] in China and to suppressinflammatory responses and tumor progression [34] Someother compounds also have been shown experimentally tohave various biological activities for example crysophanol(C42 DL = 021 OB = 1864 Caco-2 = 062) can be usedto treat menorrhagia and thrombocytopenia [35] Perlolyrine

(C52 DL = 027 OB = 6595 Caco-2 = 088) was confirmedto have a protective effect on injured human umbilical veinendothelial cells [36] and myricanone (C48 DL = 051 OB= 5761 Caco-2 = 067) was found to best inhibit mouse skintumor progression [37]

32 Target Fishing The 65 active compounds interact with185 target proteins as shown in Table 2 in other wordson average each compound on average interacts with 285target proteinsThis result confirms the polypharmacologicalcharacter of oriental medicine and demonstrates the syn-ergistic effects of multiple compounds on multiple targets[38] Different compounds in CG and DG can directly affectcommon targets for example the target protein ldquocalmodulin(CALM1)rdquo interacts with crysophanol fromCG and coniferylferulate from DG at the same time which implies thesynergetic or cumulative effects of herbal medicine

33 GO Analysis 397 biological process terms with 119875 valuesof lt001 were sorted using the functional annotation chart ofthe DAVID 68 Gene Functional Classification Tool basedon 185 filtered target genes and 119875 values were adjustedusing the Benjamini-Hochberg method 30 enriched GO BPterms extracted by 119875 value and gene counts are displayed inFigure 2 It is meaningful that most of the target genes aresignificantly related to the various BP involved in parturitionFor instance 30 extracted GO BP terms include ldquoMAPKsignaling pathwaysrdquo ldquosteroid hormone mediated signalingpathwayrdquo ldquoresponse to glucocorticoidrdquo ldquoresponse to estra-diolrdquo and ldquopositive regulation of ERK1 and ERK2 cascaderdquoldquoMAPK signaling pathwaysrdquo were reported to be activatedin human uterine cervical ripening during parturition [39]ldquoSteroid hormone mediated signaling pathwayrdquo is highly

related to parturition process as estrogen and progesteroneplay important roles in pregnancy and parturition andestrogen induceS the principal stimulatory myometrial con-tractility [40] Also estradiol takes key place in parturitionprocess [41] It was identified that increased ERK activationis observed at the onset of labor and it promotes myometrialcontractility and development of parturition [42 43] To sumup the target genes of BSS are highly associated with thebiological process (BP) of parturition

34 Network Construction and Analysis Network analysis isan efficient tool for visualizing and understanding multipletargeted drug actions and demonstrates drug actions withinthe context of the whole genome [44 45] For a better insightof therapeutic impacts H-C-T and T-P networks were con-structed and displayed in Figures 3 and 4 respectively In theH-C-T network nodes represent herb names compoundsand targets Also in the T-P network circular nodes representtargets and triangle nodes represent pathways Besides nodesize is relative to the degree and edges show interactionsbetween nodes

H-C-T network confirmed that there were 739 interac-tions between 185 targets and 65 active compounds of CGand DG oleic acid (C48 degree = 42) with the highestnumber of interactions with targets followed by succinicacid (C63 degree = 40) and stigmasterol (C62 degree =37) It shows that single molecules target multiple recep-tors [46] Also some compounds from CG and DG werefound to share common targets Likewise prostaglandinGH synthase 2 (PTGS2 degree = 56) displayed the mostaffinitive connections with compounds followed by gamma-aminobutyric acid receptor subunit alpha-1 (GABRA1 degree= 48) prostaglandin GH synthase 1 (PTGS1 degree = 37)

and muscarinic acetylcholine receptor M1 (CHRM1 degree= 37) Except for C60 (PLA2G1B degree = 1) the rest ofthe 64 active compounds are connected with more thanone target likewise 73 (395) target genes out of 185interactedwithmore than one compoundThis result demon-strates the multicompounds and multitarget properties ofherbal compounds and there was a report that compoundswith multiple targets could have greater therapeutic efficacy[47]

In addition the top 40 pathways were extracted basedon gene counts and 119875 value (lt005) and 119875 value wasadjusted by Benjamini-Hochbergmethod T-P network usingrelevant targets of herbal compounds is demonstrated inFigure 4 There were 485 interactions between the top 40pathways and 135 of 185 target genes ldquoMetabolic pathwaysrdquo(degree = 49) and ldquoneuroactive ligand-receptor interactionpathwayrdquo (degree = 32) had the highest and the secondhighest numbers of connections with the targets followedby ldquocalcium signalingrdquo (degree = 21) ldquocAMP signaling path-wayrdquo (degree = 17) and ldquocGMP PKG signaling pathwayrdquo(degree = 15) These are compelling results that parturitionprocesses are the complex hormone interactions and it iswell known that calcium signals within the myometrium arepivotal for uterine contractions [48] In the same mannersome target genes demonstrated higher degree centralitywith top 40 pathways namely PI3-kinase subunit gamma(PIK3CG degree = 23) cAMP-dependent protein kinase

catalytic subunit alpha (PRKACA degree = 20) proteinkinase C beta type (PRKCB degree = 18) and calmodulin(CALM1 degree = 11) We can confirm the same result in theprevious researches For instance PI3-kinase subunit gammaplays the key role in regulating cAMP calcium cyclingand beta-adrenergic signaling [49] Moreover during thelabor calmodulin-calcium complex activates myosin light-chain kinase which causes the generation of ATPase activityeventually uterine contraction is promoted [50]

H-C-T network explains the multitarget multicom-pounds properties and accumulates effect of herbalmedicines and T-P network shows that target genes of BSSare highly related to the pathway associated with parturi-tion process

35 Target Organ Location Map It is important to confirmthe tissue mRNA expression profiles of the target genes atthe organ level to identify the effects of BSS on parturi-tion Since there was no mRNA expression information inBioGPS of muscarinic acetylcholine receptor M1 (CHRM1)putative beta-glucuronidase-like protein SMA3 (GUSBP1)and retinol-binding protein 2 (RBP2) excluding these 3targets from 185 filtered targets totally 182 genes mRNAexpression profiles were analyzed in this studyTherewere 519interactions between target genes and organ locations Thenetworks of target genes tissuemRNAexpression profiles andcompounds of BSS are shown in Figure 5

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

(C52 DL = 027 OB = 6595 Caco-2 = 088) was confirmedto have a protective effect on injured human umbilical veinendothelial cells [36] and myricanone (C48 DL = 051 OB= 5761 Caco-2 = 067) was found to best inhibit mouse skintumor progression [37]

32 Target Fishing The 65 active compounds interact with185 target proteins as shown in Table 2 in other wordson average each compound on average interacts with 285target proteinsThis result confirms the polypharmacologicalcharacter of oriental medicine and demonstrates the syn-ergistic effects of multiple compounds on multiple targets[38] Different compounds in CG and DG can directly affectcommon targets for example the target protein ldquocalmodulin(CALM1)rdquo interacts with crysophanol fromCG and coniferylferulate from DG at the same time which implies thesynergetic or cumulative effects of herbal medicine

33 GO Analysis 397 biological process terms with 119875 valuesof lt001 were sorted using the functional annotation chart ofthe DAVID 68 Gene Functional Classification Tool basedon 185 filtered target genes and 119875 values were adjustedusing the Benjamini-Hochberg method 30 enriched GO BPterms extracted by 119875 value and gene counts are displayed inFigure 2 It is meaningful that most of the target genes aresignificantly related to the various BP involved in parturitionFor instance 30 extracted GO BP terms include ldquoMAPKsignaling pathwaysrdquo ldquosteroid hormone mediated signalingpathwayrdquo ldquoresponse to glucocorticoidrdquo ldquoresponse to estra-diolrdquo and ldquopositive regulation of ERK1 and ERK2 cascaderdquoldquoMAPK signaling pathwaysrdquo were reported to be activatedin human uterine cervical ripening during parturition [39]ldquoSteroid hormone mediated signaling pathwayrdquo is highly

related to parturition process as estrogen and progesteroneplay important roles in pregnancy and parturition andestrogen induceS the principal stimulatory myometrial con-tractility [40] Also estradiol takes key place in parturitionprocess [41] It was identified that increased ERK activationis observed at the onset of labor and it promotes myometrialcontractility and development of parturition [42 43] To sumup the target genes of BSS are highly associated with thebiological process (BP) of parturition

34 Network Construction and Analysis Network analysis isan efficient tool for visualizing and understanding multipletargeted drug actions and demonstrates drug actions withinthe context of the whole genome [44 45] For a better insightof therapeutic impacts H-C-T and T-P networks were con-structed and displayed in Figures 3 and 4 respectively In theH-C-T network nodes represent herb names compoundsand targets Also in the T-P network circular nodes representtargets and triangle nodes represent pathways Besides nodesize is relative to the degree and edges show interactionsbetween nodes

H-C-T network confirmed that there were 739 interac-tions between 185 targets and 65 active compounds of CGand DG oleic acid (C48 degree = 42) with the highestnumber of interactions with targets followed by succinicacid (C63 degree = 40) and stigmasterol (C62 degree =37) It shows that single molecules target multiple recep-tors [46] Also some compounds from CG and DG werefound to share common targets Likewise prostaglandinGH synthase 2 (PTGS2 degree = 56) displayed the mostaffinitive connections with compounds followed by gamma-aminobutyric acid receptor subunit alpha-1 (GABRA1 degree= 48) prostaglandin GH synthase 1 (PTGS1 degree = 37)

and muscarinic acetylcholine receptor M1 (CHRM1 degree= 37) Except for C60 (PLA2G1B degree = 1) the rest ofthe 64 active compounds are connected with more thanone target likewise 73 (395) target genes out of 185interactedwithmore than one compoundThis result demon-strates the multicompounds and multitarget properties ofherbal compounds and there was a report that compoundswith multiple targets could have greater therapeutic efficacy[47]

In addition the top 40 pathways were extracted basedon gene counts and 119875 value (lt005) and 119875 value wasadjusted by Benjamini-Hochbergmethod T-P network usingrelevant targets of herbal compounds is demonstrated inFigure 4 There were 485 interactions between the top 40pathways and 135 of 185 target genes ldquoMetabolic pathwaysrdquo(degree = 49) and ldquoneuroactive ligand-receptor interactionpathwayrdquo (degree = 32) had the highest and the secondhighest numbers of connections with the targets followedby ldquocalcium signalingrdquo (degree = 21) ldquocAMP signaling path-wayrdquo (degree = 17) and ldquocGMP PKG signaling pathwayrdquo(degree = 15) These are compelling results that parturitionprocesses are the complex hormone interactions and it iswell known that calcium signals within the myometrium arepivotal for uterine contractions [48] In the same mannersome target genes demonstrated higher degree centralitywith top 40 pathways namely PI3-kinase subunit gamma(PIK3CG degree = 23) cAMP-dependent protein kinase

catalytic subunit alpha (PRKACA degree = 20) proteinkinase C beta type (PRKCB degree = 18) and calmodulin(CALM1 degree = 11) We can confirm the same result in theprevious researches For instance PI3-kinase subunit gammaplays the key role in regulating cAMP calcium cyclingand beta-adrenergic signaling [49] Moreover during thelabor calmodulin-calcium complex activates myosin light-chain kinase which causes the generation of ATPase activityeventually uterine contraction is promoted [50]

H-C-T network explains the multitarget multicom-pounds properties and accumulates effect of herbalmedicines and T-P network shows that target genes of BSSare highly related to the pathway associated with parturi-tion process

35 Target Organ Location Map It is important to confirmthe tissue mRNA expression profiles of the target genes atthe organ level to identify the effects of BSS on parturi-tion Since there was no mRNA expression information inBioGPS of muscarinic acetylcholine receptor M1 (CHRM1)putative beta-glucuronidase-like protein SMA3 (GUSBP1)and retinol-binding protein 2 (RBP2) excluding these 3targets from 185 filtered targets totally 182 genes mRNAexpression profiles were analyzed in this studyTherewere 519interactions between target genes and organ locations Thenetworks of target genes tissuemRNAexpression profiles andcompounds of BSS are shown in Figure 5

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

(C52 DL = 027 OB = 6595 Caco-2 = 088) was confirmedto have a protective effect on injured human umbilical veinendothelial cells [36] and myricanone (C48 DL = 051 OB= 5761 Caco-2 = 067) was found to best inhibit mouse skintumor progression [37]

32 Target Fishing The 65 active compounds interact with185 target proteins as shown in Table 2 in other wordson average each compound on average interacts with 285target proteinsThis result confirms the polypharmacologicalcharacter of oriental medicine and demonstrates the syn-ergistic effects of multiple compounds on multiple targets[38] Different compounds in CG and DG can directly affectcommon targets for example the target protein ldquocalmodulin(CALM1)rdquo interacts with crysophanol fromCG and coniferylferulate from DG at the same time which implies thesynergetic or cumulative effects of herbal medicine

In addition the top 40 pathways were extracted basedon gene counts and 119875 value (lt005) and 119875 value wasadjusted by Benjamini-Hochbergmethod T-P network usingrelevant targets of herbal compounds is demonstrated inFigure 4 There were 485 interactions between the top 40pathways and 135 of 185 target genes ldquoMetabolic pathwaysrdquo(degree = 49) and ldquoneuroactive ligand-receptor interactionpathwayrdquo (degree = 32) had the highest and the secondhighest numbers of connections with the targets followedby ldquocalcium signalingrdquo (degree = 21) ldquocAMP signaling path-wayrdquo (degree = 17) and ldquocGMP PKG signaling pathwayrdquo(degree = 15) These are compelling results that parturitionprocesses are the complex hormone interactions and it iswell known that calcium signals within the myometrium arepivotal for uterine contractions [48] In the same mannersome target genes demonstrated higher degree centralitywith top 40 pathways namely PI3-kinase subunit gamma(PIK3CG degree = 23) cAMP-dependent protein kinase

catalytic subunit alpha (PRKACA degree = 20) proteinkinase C beta type (PRKCB degree = 18) and calmodulin(CALM1 degree = 11) We can confirm the same result in theprevious researches For instance PI3-kinase subunit gammaplays the key role in regulating cAMP calcium cyclingand beta-adrenergic signaling [49] Moreover during thelabor calmodulin-calcium complex activates myosin light-chain kinase which causes the generation of ATPase activityeventually uterine contraction is promoted [50]

H-C-T network explains the multitarget multicom-pounds properties and accumulates effect of herbalmedicines and T-P network shows that target genes of BSSare highly related to the pathway associated with parturi-tion process

35 Target Organ Location Map It is important to confirmthe tissue mRNA expression profiles of the target genes atthe organ level to identify the effects of BSS on parturi-tion Since there was no mRNA expression information inBioGPS of muscarinic acetylcholine receptor M1 (CHRM1)putative beta-glucuronidase-like protein SMA3 (GUSBP1)and retinol-binding protein 2 (RBP2) excluding these 3targets from 185 filtered targets totally 182 genes mRNAexpression profiles were analyzed in this studyTherewere 519interactions between target genes and organ locations Thenetworks of target genes tissuemRNAexpression profiles andcompounds of BSS are shown in Figure 5

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

Figure 5 Target organ location map it shows that tissue-specific patterns of mRNA expression are highly active in relative organs ofparturition process such as uterus fetus placenta hypothalamus pituitary and smooth muscle Yellow nodes show compounds and pinknodes indicate targets and node size is relative to the degree and edges demonstrate interactions between nodes

related organ tissues such as those of the uterus placentafetus hypothalamus and pituitary gland

This study employed the network analytical methodsto show the multicompound multitarget properties of BSSThe results not only support clinical applications of BSS oneasing childbirth but also suggest the related target genes andpathways of BSS on promoting parturition according to asystems-level in silico analytic approach However detailedmechanisms and other functions of BSS should be discussedfurther

and muscarinic acetylcholine receptor M1 (CHRM1 degree= 37) Except for C60 (PLA2G1B degree = 1) the rest ofthe 64 active compounds are connected with more thanone target likewise 73 (395) target genes out of 185interactedwithmore than one compoundThis result demon-strates the multicompounds and multitarget properties ofherbal compounds and there was a report that compoundswith multiple targets could have greater therapeutic efficacy[47]

In addition the top 40 pathways were extracted basedon gene counts and 119875 value (lt005) and 119875 value wasadjusted by Benjamini-Hochbergmethod T-P network usingrelevant targets of herbal compounds is demonstrated inFigure 4 There were 485 interactions between the top 40pathways and 135 of 185 target genes ldquoMetabolic pathwaysrdquo(degree = 49) and ldquoneuroactive ligand-receptor interactionpathwayrdquo (degree = 32) had the highest and the secondhighest numbers of connections with the targets followedby ldquocalcium signalingrdquo (degree = 21) ldquocAMP signaling path-wayrdquo (degree = 17) and ldquocGMP PKG signaling pathwayrdquo(degree = 15) These are compelling results that parturitionprocesses are the complex hormone interactions and it iswell known that calcium signals within the myometrium arepivotal for uterine contractions [48] In the same mannersome target genes demonstrated higher degree centralitywith top 40 pathways namely PI3-kinase subunit gamma(PIK3CG degree = 23) cAMP-dependent protein kinase

catalytic subunit alpha (PRKACA degree = 20) proteinkinase C beta type (PRKCB degree = 18) and calmodulin(CALM1 degree = 11) We can confirm the same result in theprevious researches For instance PI3-kinase subunit gammaplays the key role in regulating cAMP calcium cyclingand beta-adrenergic signaling [49] Moreover during thelabor calmodulin-calcium complex activates myosin light-chain kinase which causes the generation of ATPase activityeventually uterine contraction is promoted [50]

H-C-T network explains the multitarget multicom-pounds properties and accumulates effect of herbalmedicines and T-P network shows that target genes of BSSare highly related to the pathway associated with parturi-tion process

35 Target Organ Location Map It is important to confirmthe tissue mRNA expression profiles of the target genes atthe organ level to identify the effects of BSS on parturi-tion Since there was no mRNA expression information inBioGPS of muscarinic acetylcholine receptor M1 (CHRM1)putative beta-glucuronidase-like protein SMA3 (GUSBP1)and retinol-binding protein 2 (RBP2) excluding these 3targets from 185 filtered targets totally 182 genes mRNAexpression profiles were analyzed in this studyTherewere 519interactions between target genes and organ locations Thenetworks of target genes tissuemRNAexpression profiles andcompounds of BSS are shown in Figure 5

Figure 2GOanalysis 30 enriched biological process (BP) of gene ontology (GO) terms sorted by119875 valuelt 001 and gene counts are displayedThe 119910-axis represents enriched biological process (BP) terms for the target genes and the 119909-axis shows gene counts and minus log 10 (119875 value)

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

in all of 6 groups For instance muscarinic acetylcholinereceptor M2 (CHRM2) neuronal acetylcholine receptorsubunit 120572-2 (CHRNA2) gamma-aminobutyric acid receptorsubunit alpha-3 (GABRA3) NO synthase inducible (NOS2)cGMP-inhibited 3101584051015840-cyclic phosphodiesterase A (PDE3A)and sodium-dependent dopamine transporter (SLC6A3)recorded beyond average mRNA expression in all six groupsFurthermore 79 of targets were expressed in two or moreorgan tissues which suggests that those organs and targetgenes of BSS are closely correlated

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

and muscarinic acetylcholine receptor M1 (CHRM1 degree= 37) Except for C60 (PLA2G1B degree = 1) the rest ofthe 64 active compounds are connected with more thanone target likewise 73 (395) target genes out of 185interactedwithmore than one compoundThis result demon-strates the multicompounds and multitarget properties ofherbal compounds and there was a report that compoundswith multiple targets could have greater therapeutic efficacy[47]

In addition the top 40 pathways were extracted basedon gene counts and 119875 value (lt005) and 119875 value wasadjusted by Benjamini-Hochbergmethod T-P network usingrelevant targets of herbal compounds is demonstrated inFigure 4 There were 485 interactions between the top 40pathways and 135 of 185 target genes ldquoMetabolic pathwaysrdquo(degree = 49) and ldquoneuroactive ligand-receptor interactionpathwayrdquo (degree = 32) had the highest and the secondhighest numbers of connections with the targets followedby ldquocalcium signalingrdquo (degree = 21) ldquocAMP signaling path-wayrdquo (degree = 17) and ldquocGMP PKG signaling pathwayrdquo(degree = 15) These are compelling results that parturitionprocesses are the complex hormone interactions and it iswell known that calcium signals within the myometrium arepivotal for uterine contractions [48] In the same mannersome target genes demonstrated higher degree centralitywith top 40 pathways namely PI3-kinase subunit gamma(PIK3CG degree = 23) cAMP-dependent protein kinase

catalytic subunit alpha (PRKACA degree = 20) proteinkinase C beta type (PRKCB degree = 18) and calmodulin(CALM1 degree = 11) We can confirm the same result in theprevious researches For instance PI3-kinase subunit gammaplays the key role in regulating cAMP calcium cyclingand beta-adrenergic signaling [49] Moreover during thelabor calmodulin-calcium complex activates myosin light-chain kinase which causes the generation of ATPase activityeventually uterine contraction is promoted [50]

H-C-T network explains the multitarget multicom-pounds properties and accumulates effect of herbalmedicines and T-P network shows that target genes of BSSare highly related to the pathway associated with parturi-tion process

35 Target Organ Location Map It is important to confirmthe tissue mRNA expression profiles of the target genes atthe organ level to identify the effects of BSS on parturi-tion Since there was no mRNA expression information inBioGPS of muscarinic acetylcholine receptor M1 (CHRM1)putative beta-glucuronidase-like protein SMA3 (GUSBP1)and retinol-binding protein 2 (RBP2) excluding these 3targets from 185 filtered targets totally 182 genes mRNAexpression profiles were analyzed in this studyTherewere 519interactions between target genes and organ locations Thenetworks of target genes tissuemRNAexpression profiles andcompounds of BSS are shown in Figure 5

Figure 2GOanalysis 30 enriched biological process (BP) of gene ontology (GO) terms sorted by119875 valuelt 001 and gene counts are displayedThe 119910-axis represents enriched biological process (BP) terms for the target genes and the 119909-axis shows gene counts and minus log 10 (119875 value)

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

in all of 6 groups For instance muscarinic acetylcholinereceptor M2 (CHRM2) neuronal acetylcholine receptorsubunit 120572-2 (CHRNA2) gamma-aminobutyric acid receptorsubunit alpha-3 (GABRA3) NO synthase inducible (NOS2)cGMP-inhibited 3101584051015840-cyclic phosphodiesterase A (PDE3A)and sodium-dependent dopamine transporter (SLC6A3)recorded beyond average mRNA expression in all six groupsFurthermore 79 of targets were expressed in two or moreorgan tissues which suggests that those organs and targetgenes of BSS are closely correlated

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

water soluble polysaccharide but coumarin which is liposol-uble including nodakenin (1) peucedanone (2) marmesin(3) decursinol (4) 7-hydroxy-6-(2R-hydroxy-3-methylbut-3-enyl) coumarin (5) demethylsuberosin (6) decursin (7)decursinol angelate (8) and isoimperatorin (9) [56] Ofthese decursin and its isomer decursinol angelate have beenreported to be the active compounds in AGR [57] It wasidentified in the experimental studies that AGR and DGact via different mechanisms in the cardiovascular centralnervous system and anticancer activity but both have similarpharmacological effects [57] Since the compositions of DGand AGR differ further study on BSS with AGR is requiredCurrently BSS is commonly prescribed to treat cerebravascular and cardiovascular diseases in China [33] but inKorea BSS is widely applied in obstetrics

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

Figure 5 Target organ location map it shows that tissue-specific patterns of mRNA expression are highly active in relative organs ofparturition process such as uterus fetus placenta hypothalamus pituitary and smooth muscle Yellow nodes show compounds and pinknodes indicate targets and node size is relative to the degree and edges demonstrate interactions between nodes

related organ tissues such as those of the uterus placentafetus hypothalamus and pituitary gland

This study employed the network analytical methodsto show the multicompound multitarget properties of BSSThe results not only support clinical applications of BSS oneasing childbirth but also suggest the related target genes andpathways of BSS on promoting parturition according to asystems-level in silico analytic approach However detailedmechanisms and other functions of BSS should be discussedfurther

and muscarinic acetylcholine receptor M1 (CHRM1 degree= 37) Except for C60 (PLA2G1B degree = 1) the rest ofthe 64 active compounds are connected with more thanone target likewise 73 (395) target genes out of 185interactedwithmore than one compoundThis result demon-strates the multicompounds and multitarget properties ofherbal compounds and there was a report that compoundswith multiple targets could have greater therapeutic efficacy[47]

In addition the top 40 pathways were extracted basedon gene counts and 119875 value (lt005) and 119875 value wasadjusted by Benjamini-Hochbergmethod T-P network usingrelevant targets of herbal compounds is demonstrated inFigure 4 There were 485 interactions between the top 40pathways and 135 of 185 target genes ldquoMetabolic pathwaysrdquo(degree = 49) and ldquoneuroactive ligand-receptor interactionpathwayrdquo (degree = 32) had the highest and the secondhighest numbers of connections with the targets followedby ldquocalcium signalingrdquo (degree = 21) ldquocAMP signaling path-wayrdquo (degree = 17) and ldquocGMP PKG signaling pathwayrdquo(degree = 15) These are compelling results that parturitionprocesses are the complex hormone interactions and it iswell known that calcium signals within the myometrium arepivotal for uterine contractions [48] In the same mannersome target genes demonstrated higher degree centralitywith top 40 pathways namely PI3-kinase subunit gamma(PIK3CG degree = 23) cAMP-dependent protein kinase

catalytic subunit alpha (PRKACA degree = 20) proteinkinase C beta type (PRKCB degree = 18) and calmodulin(CALM1 degree = 11) We can confirm the same result in theprevious researches For instance PI3-kinase subunit gammaplays the key role in regulating cAMP calcium cyclingand beta-adrenergic signaling [49] Moreover during thelabor calmodulin-calcium complex activates myosin light-chain kinase which causes the generation of ATPase activityeventually uterine contraction is promoted [50]

H-C-T network explains the multitarget multicom-pounds properties and accumulates effect of herbalmedicines and T-P network shows that target genes of BSSare highly related to the pathway associated with parturi-tion process

35 Target Organ Location Map It is important to confirmthe tissue mRNA expression profiles of the target genes atthe organ level to identify the effects of BSS on parturi-tion Since there was no mRNA expression information inBioGPS of muscarinic acetylcholine receptor M1 (CHRM1)putative beta-glucuronidase-like protein SMA3 (GUSBP1)and retinol-binding protein 2 (RBP2) excluding these 3targets from 185 filtered targets totally 182 genes mRNAexpression profiles were analyzed in this studyTherewere 519interactions between target genes and organ locations Thenetworks of target genes tissuemRNAexpression profiles andcompounds of BSS are shown in Figure 5

Figure 2GOanalysis 30 enriched biological process (BP) of gene ontology (GO) terms sorted by119875 valuelt 001 and gene counts are displayedThe 119910-axis represents enriched biological process (BP) terms for the target genes and the 119909-axis shows gene counts and minus log 10 (119875 value)

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

in all of 6 groups For instance muscarinic acetylcholinereceptor M2 (CHRM2) neuronal acetylcholine receptorsubunit 120572-2 (CHRNA2) gamma-aminobutyric acid receptorsubunit alpha-3 (GABRA3) NO synthase inducible (NOS2)cGMP-inhibited 3101584051015840-cyclic phosphodiesterase A (PDE3A)and sodium-dependent dopamine transporter (SLC6A3)recorded beyond average mRNA expression in all six groupsFurthermore 79 of targets were expressed in two or moreorgan tissues which suggests that those organs and targetgenes of BSS are closely correlated

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

and muscarinic acetylcholine receptor M1 (CHRM1 degree= 37) Except for C60 (PLA2G1B degree = 1) the rest ofthe 64 active compounds are connected with more thanone target likewise 73 (395) target genes out of 185interactedwithmore than one compoundThis result demon-strates the multicompounds and multitarget properties ofherbal compounds and there was a report that compoundswith multiple targets could have greater therapeutic efficacy[47]

In addition the top 40 pathways were extracted basedon gene counts and 119875 value (lt005) and 119875 value wasadjusted by Benjamini-Hochbergmethod T-P network usingrelevant targets of herbal compounds is demonstrated inFigure 4 There were 485 interactions between the top 40pathways and 135 of 185 target genes ldquoMetabolic pathwaysrdquo(degree = 49) and ldquoneuroactive ligand-receptor interactionpathwayrdquo (degree = 32) had the highest and the secondhighest numbers of connections with the targets followedby ldquocalcium signalingrdquo (degree = 21) ldquocAMP signaling path-wayrdquo (degree = 17) and ldquocGMP PKG signaling pathwayrdquo(degree = 15) These are compelling results that parturitionprocesses are the complex hormone interactions and it iswell known that calcium signals within the myometrium arepivotal for uterine contractions [48] In the same mannersome target genes demonstrated higher degree centralitywith top 40 pathways namely PI3-kinase subunit gamma(PIK3CG degree = 23) cAMP-dependent protein kinase

catalytic subunit alpha (PRKACA degree = 20) proteinkinase C beta type (PRKCB degree = 18) and calmodulin(CALM1 degree = 11) We can confirm the same result in theprevious researches For instance PI3-kinase subunit gammaplays the key role in regulating cAMP calcium cyclingand beta-adrenergic signaling [49] Moreover during thelabor calmodulin-calcium complex activates myosin light-chain kinase which causes the generation of ATPase activityeventually uterine contraction is promoted [50]

H-C-T network explains the multitarget multicom-pounds properties and accumulates effect of herbalmedicines and T-P network shows that target genes of BSSare highly related to the pathway associated with parturi-tion process

35 Target Organ Location Map It is important to confirmthe tissue mRNA expression profiles of the target genes atthe organ level to identify the effects of BSS on parturi-tion Since there was no mRNA expression information inBioGPS of muscarinic acetylcholine receptor M1 (CHRM1)putative beta-glucuronidase-like protein SMA3 (GUSBP1)and retinol-binding protein 2 (RBP2) excluding these 3targets from 185 filtered targets totally 182 genes mRNAexpression profiles were analyzed in this studyTherewere 519interactions between target genes and organ locations Thenetworks of target genes tissuemRNAexpression profiles andcompounds of BSS are shown in Figure 5

Figure 2GOanalysis 30 enriched biological process (BP) of gene ontology (GO) terms sorted by119875 valuelt 001 and gene counts are displayedThe 119910-axis represents enriched biological process (BP) terms for the target genes and the 119909-axis shows gene counts and minus log 10 (119875 value)

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

in all of 6 groups For instance muscarinic acetylcholinereceptor M2 (CHRM2) neuronal acetylcholine receptorsubunit 120572-2 (CHRNA2) gamma-aminobutyric acid receptorsubunit alpha-3 (GABRA3) NO synthase inducible (NOS2)cGMP-inhibited 3101584051015840-cyclic phosphodiesterase A (PDE3A)and sodium-dependent dopamine transporter (SLC6A3)recorded beyond average mRNA expression in all six groupsFurthermore 79 of targets were expressed in two or moreorgan tissues which suggests that those organs and targetgenes of BSS are closely correlated

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

water soluble polysaccharide but coumarin which is liposol-uble including nodakenin (1) peucedanone (2) marmesin(3) decursinol (4) 7-hydroxy-6-(2R-hydroxy-3-methylbut-3-enyl) coumarin (5) demethylsuberosin (6) decursin (7)decursinol angelate (8) and isoimperatorin (9) [56] Ofthese decursin and its isomer decursinol angelate have beenreported to be the active compounds in AGR [57] It wasidentified in the experimental studies that AGR and DGact via different mechanisms in the cardiovascular centralnervous system and anticancer activity but both have similarpharmacological effects [57] Since the compositions of DGand AGR differ further study on BSS with AGR is requiredCurrently BSS is commonly prescribed to treat cerebravascular and cardiovascular diseases in China [33] but inKorea BSS is widely applied in obstetrics

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

Figure 2GOanalysis 30 enriched biological process (BP) of gene ontology (GO) terms sorted by119875 valuelt 001 and gene counts are displayedThe 119910-axis represents enriched biological process (BP) terms for the target genes and the 119909-axis shows gene counts and minus log 10 (119875 value)

As a result 159 of 182 target genes displayed beyond aver-agemRNAexpression in relevant organ tissues such as uterusandor uterus corpus fetus andor placenta hypothalamusandor pituitary smoothmuscle andwhole bloodThe rest of23 genes of 182 targets did not display above average mRNAexpression in above organ tissues for example gamma-aminobutyric acid receptor subunit alpha-6 (GABRA6) andcoagulation factor X (F10)

Nevertheless most genes of 159 demonstrated highexpression patterns in several organs of parturition relatedtissues at the same time In detail 60 genes showed mostsignificantmRNA expression in the uterus andor uterus cor-pus group 130 for placenta andor fetus 86 for hypothalamusandor pituitary 82 for smoothmuscle 80 for pituitary and 81for whole blood Besides 30 of 159 genes showed expression

in all of 6 groups For instance muscarinic acetylcholinereceptor M2 (CHRM2) neuronal acetylcholine receptorsubunit 120572-2 (CHRNA2) gamma-aminobutyric acid receptorsubunit alpha-3 (GABRA3) NO synthase inducible (NOS2)cGMP-inhibited 3101584051015840-cyclic phosphodiesterase A (PDE3A)and sodium-dependent dopamine transporter (SLC6A3)recorded beyond average mRNA expression in all six groupsFurthermore 79 of targets were expressed in two or moreorgan tissues which suggests that those organs and targetgenes of BSS are closely correlated

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

water soluble polysaccharide but coumarin which is liposol-uble including nodakenin (1) peucedanone (2) marmesin(3) decursinol (4) 7-hydroxy-6-(2R-hydroxy-3-methylbut-3-enyl) coumarin (5) demethylsuberosin (6) decursin (7)decursinol angelate (8) and isoimperatorin (9) [56] Ofthese decursin and its isomer decursinol angelate have beenreported to be the active compounds in AGR [57] It wasidentified in the experimental studies that AGR and DGact via different mechanisms in the cardiovascular centralnervous system and anticancer activity but both have similarpharmacological effects [57] Since the compositions of DGand AGR differ further study on BSS with AGR is requiredCurrently BSS is commonly prescribed to treat cerebravascular and cardiovascular diseases in China [33] but inKorea BSS is widely applied in obstetrics

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

Figure 3 H-C-T network herb-compound-target (H-C-T) network demonstrated multicompound multitarget property of BSS In thisnetwork red and blue nodes represent herbs green nodes show compounds and pink nodes indicate targets and node size is relative to thedegree and edges demonstrate interactions between nodes

network analysis and relevant organ location mapping wasused to explain the targets of BSS in relation to the parturitionprocess There is no denying that network based analysis ispowerful approach for identifying the actions of multitarget-ing herbal medicines at the systems level and our study showstarget genes of BSS are strongly connected to parturitionrelated pathways biological processes and organs It wasconfirmed that 98 of the active compounds of BSS wereinteracted with more than two targets and 395 of thetargets related to more than one compound The synergeticmultitarget properties of BSS were visualized but furtherdiscussion about differentiated drug action based on degreecentrality and simultaneous targeting effect of more than onecompound is required [51] Also detailed potential pathwaysof BSS should be explored deeply in the future

Similar findings were identified in a few RCT researchesin China that using BSS in induction of labor can reduce

the delivery time the amount of bleeding and the residualrate of placenta [52 53] In addition BSS targets six genes ofGABA receptor and NOS which was reported to be relatedoxytocin neurons at the time of parturition in rats [54] AlsoBSS targets NOS and NO (nitric oxide) which are involved inthe regulation of uterine contractility during pregnancy andis a key factor for the onset of labor [55] and iNOS (induciblenitric oxide synthase) can be upregulated accordantly bysimilar inflammatory mediators during ripening [11]

In fact rather than DG Angelicae Gigantis Radix (Dang-gwi AGR) grows naturally in Korea for that reason thecombination of AGR and CG is commonly used as BSSin Korea Instead DG is named as Chinese Danggwi foraccurate classification in Korea Several studies have shownAGR is differs from DG in terms of its main active con-stituents and genetic form AGR is mainly composed of

water soluble polysaccharide but coumarin which is liposol-uble including nodakenin (1) peucedanone (2) marmesin(3) decursinol (4) 7-hydroxy-6-(2R-hydroxy-3-methylbut-3-enyl) coumarin (5) demethylsuberosin (6) decursin (7)decursinol angelate (8) and isoimperatorin (9) [56] Ofthese decursin and its isomer decursinol angelate have beenreported to be the active compounds in AGR [57] It wasidentified in the experimental studies that AGR and DGact via different mechanisms in the cardiovascular centralnervous system and anticancer activity but both have similarpharmacological effects [57] Since the compositions of DGand AGR differ further study on BSS with AGR is requiredCurrently BSS is commonly prescribed to treat cerebravascular and cardiovascular diseases in China [33] but inKorea BSS is widely applied in obstetrics

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

Figure 5 Target organ location map it shows that tissue-specific patterns of mRNA expression are highly active in relative organs ofparturition process such as uterus fetus placenta hypothalamus pituitary and smooth muscle Yellow nodes show compounds and pinknodes indicate targets and node size is relative to the degree and edges demonstrate interactions between nodes

related organ tissues such as those of the uterus placentafetus hypothalamus and pituitary gland

This study employed the network analytical methodsto show the multicompound multitarget properties of BSSThe results not only support clinical applications of BSS oneasing childbirth but also suggest the related target genes andpathways of BSS on promoting parturition according to asystems-level in silico analytic approach However detailedmechanisms and other functions of BSS should be discussedfurther

Figure 4 T-P network in target-pathway (T-P) network circular nodes represent compounds and triangles indicate pathways Node size isrelative to the degree and edges demonstrate interactions between nodes

water soluble polysaccharide but coumarin which is liposol-uble including nodakenin (1) peucedanone (2) marmesin(3) decursinol (4) 7-hydroxy-6-(2R-hydroxy-3-methylbut-3-enyl) coumarin (5) demethylsuberosin (6) decursin (7)decursinol angelate (8) and isoimperatorin (9) [56] Ofthese decursin and its isomer decursinol angelate have beenreported to be the active compounds in AGR [57] It wasidentified in the experimental studies that AGR and DGact via different mechanisms in the cardiovascular centralnervous system and anticancer activity but both have similarpharmacological effects [57] Since the compositions of DGand AGR differ further study on BSS with AGR is requiredCurrently BSS is commonly prescribed to treat cerebravascular and cardiovascular diseases in China [33] but inKorea BSS is widely applied in obstetrics

The similarity between cervical ripening during partu-rition and inflammatory reaction has been pointed out inearlier studies this has been attributed to the inductionof leukocyte migration into tissue thus promoting cervical

remodeling and parturition by estrogen [58] Further studyis needed in terms of the effect of BSS on inflammatoryreactions and parturition

Furthermore theCG-DGherb pair has other names suchas Gunggui-tang (weight ratios of 2 3 or 1 1) Ogeum-san(1 1) Iphyo-san (1 1) and Sinmyo Bulsu-san (1 2) thoseare prepared at different weight ratios [3] Accordinglyweight ratio should be determined based on considerationsof targeted symptoms for relevant clinical applications

5 Conclusion

This study results show that Bulsu-san (BSS) is highlyconnected to the parturition related pathways biologicalprocesses and organsMost compounds inBSSwork togetherwith multiple target genes in a synergetic way and this wasconfirmed using herb-compound-target network and target-pathway network analysis The mRNA expression of relevanttarget genes of BSS was elevated significantly in parturition

Figure 5 Target organ location map it shows that tissue-specific patterns of mRNA expression are highly active in relative organs ofparturition process such as uterus fetus placenta hypothalamus pituitary and smooth muscle Yellow nodes show compounds and pinknodes indicate targets and node size is relative to the degree and edges demonstrate interactions between nodes

related organ tissues such as those of the uterus placentafetus hypothalamus and pituitary gland

This study employed the network analytical methodsto show the multicompound multitarget properties of BSSThe results not only support clinical applications of BSS oneasing childbirth but also suggest the related target genes andpathways of BSS on promoting parturition according to asystems-level in silico analytic approach However detailedmechanisms and other functions of BSS should be discussedfurther
