Research synopsisResearch in the Department is focused on two areas: a) the aetiology and pathogenesis of obesity, diabetes and related metabolic disorders, and b) the molecular cell biology of membrane traffic. Investigators working in metabolic disorders are largely based in the Institute of Metabolic Science (IMS). The Cell Biology group is located entirely in The Cambridge Institute for Medical Research (CIMR). The Department has played a leading role in several recent major initiatives, including the opening of the IMS, the creation of the MRC Centre for Obesity and Related Metabolic Disease (MRC CORD) and the Cambridge Phenomics Centre. Professor Stephen O'Rahilly is Scientific Director of the NIHR Cambridge Biomedical Research Centre, and leads the Metabolic, Endocrine and Bone Theme.

Diabetes, Obesity and Metabolism GroupResearch themes include the following: molecular mechanisms in human obesity insulin resistance and type 2 diabetes (Barroso, Farooqi, O’Rahilly, Savage, Semple, in collaboration with Prof NJ Wareham and colleagues from the MRC Epidemiology Unit) neurobiology of hunger and satiety (Farooqi, with Prof P Fletcher, Dept of Psychiatry); animal models of obesity and insulin resistance (Coll, Sethi, O’Rahilly, Voshol, Vidal-Puig, Yeo); adipocyte biology (Rochford, Sethi, Vidal-Puig) and how this relates to ‘lipotoxicity’ resulting from inappropriate storage of excess lipids (Vidal-Puig); developmental programming of late-onset metabolic disease (Ozanne); signaling by insulin and insulin-like growth factors (Semple, Siddle); endoplasmic reticulum stress (Ron, Harding, Volmer), entero-endocrine physiology (Gribble, Reimann), non-transcriptional control of circadian rhythms (O’Neill) and improving health outcomes in diabetes.

Main research themes

Traumatic brain injury and strokeThe Wolfson Brain Imaging Centre (WBIC) uses positron emission tomography (PET) and magnetic resonance (MR) data to investigate disease mechanisms in traumatic brain injury and neurodegeneration. Adrian Carpenter is establishing the technology for combined PET/MR imaging and elastography. Franklin Aigbirhio is developing novel radiopharmaceutical probes for molecular imaging using PET. Tim Fryer directs an imaging programme that has introduced experimental microPET and the computing support for experimental and clinical aspects of PET and Cyclotron physics. Guy Williams directs the computing

and imaging MR science group with the development of real-time MR for brain-computer interface studies of patients with low awareness.

Marek Czosnyka leads the neurosurgical physics group whose research focuses on cerebral autoregulation following head injury and subarachnoid haemorrhage, and the importance of cerebrovascular and CSF dynamics for hydrocephalus and idiopathic intracranial hypertension. Peter Smielewski has developed software (www.neurosurg.cam.ac.uk/icmplus) required to capture and analyse real-time signals derived from bedside monitoring now introduced into several neuroscience intensive care units worldwide.

John Pickard leads a research group that explores the pathophysiology of traumatic brain injury from initial ictus through intensive care to final outcome using PET, MR and multimodality bedside monitoring. Recent advances include the definition of how early insults after head injury lead to late changes in the brain and cognitive outcome, the effects of cognitive stimulation on brain activation in altered states of consciousness (with David Menon, Department of Medicine), and new insights into parts of the brain affected by hydrocephalus and idiopathic intracranial hypertension including the development of venous stenting (with Nicholas Higgins, Neuroradiology).

Peter Hutchinson has developed care pathways from acute emergency treatment through to neuro-rehabilitation and leads the MRC RESCUEicp (evaluation of Decompressive Craniectomy for raised intracranial pressure following trauma: www.RESCUEicp.com). With Keri Carpenter, he uses intracerebral microdialysis to study changes in metabolic pathways and energy substrates used by the brain to conserve function after traumatic injury; the role of acute inflammation after head injury; and the penetration of neuroprotective agents across the blood brain barrier.

Peter Kirkpatrick leads translational research into neuroprotection, carotid atheroma imaging, and the pathophysiology of cerebrovascular disease. He uses non-invasive assessments of cerebral haemodynamics to improve outcome from cerebrovascular neurosurgical procedures; and leads the STASH (STatins in Aneurysmal Subarachnoid Haemorrhage) trial.

Liz Warburton is studying mechanisms of deterioration and recovery of speech and motor function after stroke. Perfusion and metabolic consequences of acute stroke and the nature of tissue injury are being characterised; and carotid artery plaque imaged and correlated with microembolism and watershed ischaemia. Plasticity for motor, visual and language functions is being studied in relation to clinical outcome using MRI and PET.

Dementia and neurodegenerationPeter St George Hyslop studies the genetics of Alzheimer’s and related disorders and is using structural biology to develop novel molecules for inhibiting the formation of intracellular protein aggregates that destroy nerve cells.

5CLINICAL NEUROSCIENCE

Peter Nestor works in the Herchel Smith Building for Brain and Mind Sciences on the early features of Alzheimer’s disease, frontotemporal dementia, and related disorders – combining cognitive neuropsychology with structural, metabolic and amyloid brain imaging, and quantitative neuropathology. Recent work has focused on defining the nature of early neuronal vulnerability in incipient Alzheimer’s disease and the development of structural image analyses as surrogates for the regional molecular pathology.

Maria-Grazia Spillantini has provided molecular classifications for disorders characterised by intracellular aggregates of microtubule-associated proteins (tau and alpha-synuclein) and studies mechanisms of intracellular protein aggregation in human brain tissue and transgenic mice. The focus is on accumulation of alpha-synuclein in the substantia nigra and studies on the microtubule associated protein tau which binds the motor protein dynactin and is abnormally distributed in the brain of patients with MAPT mutations and relevant transgenic mice.

James Rowe provides a bridge between the Department of Clinical Neurosciences, the Herchel Smith Building for Brain and Mind Sciences and the MRC Cognition and Brain Sciences Unit. He investigates behavioural disorders associated with neurodegenerative disease and focal brain injury using structural and functional magnetic resonance imaging and magnetoencephalography. The focus is on restoring function in the brain networks that enable the cognitive control of actions in neurodegeneration, especially Parkinson’s disease, frontotemporal dementia and progressive supranuclear palsy.

Roger Barker conducts clinical work that improves prediction across the spectrum of clinical deficits in Parkinson's and Huntington’s disease using biomarkers for the natural history and heterogeneity of these disorders in epidemiological studies of cohorts studied for clinical and imaging phenotypes, and genomics. He studies abnormalities in adult neural stem cell turnover and differentiation in transgenic models of neurodegeneration, work that has implications for the translation of novel therapies including the use of cell-based therapies for Parkinson’s and Huntington’s disease.

Plasticity and brain repairJames Fawcett works on recovery of function through adaptation, plasticity and repair of the injured brain and spinal cord. In axon regeneration the focus is on removing inhibitory chondroitin sulphate proteoglycans produced in scar tissue after damage, and using integrin engineering to enhance the ability of axons to regenerate. In plasticity, the enzyme chondroitinase is being used to degrade the inhibitory proteoglycan structures that normally prevent plasticity in the adult nervous system. The work is seeing applications not only in experimental studies of injury but also in neurodegeneration including Alzheimer’s disease.

Keith Martin studies the mechanisms of visual loss in glaucoma, and is currently investigating the integration of stem cells into the

retina in experimental glaucoma, and studying the role of axonal transport dysfunction associated with glaucomatous retinal ganglion cell death.

Stefano Pluchino works in regenerative neuroscience and studies the physiology of neural stem cells and their application in cell therapies for repair of the central nervous system. He also aims at modeling their role in modulating the fate of inflammatory and degenerative lesions – work that relates to the clinical problems of multiple sclerosis, stroke, spinal cord injury, Parkinson’s disease and glioma.

Multiple sclerosisStephen Sawcer and Alastair Compston use whole genome screening to study the genetics of multiple sclerosis and Parkinson’s disease as part of national and international consortia. They have recently identified 57 susceptibility genes, including 34 not previously considered, that demonstrate a genetic basis for the primary role of cell-mediated immune mechanisms in the pathogenesis of multiple sclerosis.

Alasdair Coles and Alastair Compston lead international trials of lemtrada (formerly Campath-1H and alemtuzumab) in early active relapsing-remitting multiple sclerosis; results from the two Phase III trials will be available in 2011 with proposed application for a drug licence in 2012. Their laboratory work focuses on the mechanisms of autoimmunity after alemtuzumab; strategies to avoid the development of anti-idiotypic auto-antibodies; and interactions between inflammatory and neurobiological processes that underlie the sustained recovery of function seen in most patients. A Phase II study in secondary progressive multiple sclerosis using autologous bone marrow-derived mesenchymal stem cells showing preliminary evidence for structural, functional and physiological improvement consistent with neuroprotection has recently been completed.

Other topicsColin Watts has a programme of research in neuro-oncology that combines Phase I/II clinical trials with biomarker-based stratification of participants; development and evaluation of a Brain Tumour Symptom Algorithm for Primary Care (BraTSA: collaboration with the Cambridge University Primary Care Research Unit); and improved treatment for cerebral metastatic disease. Stephen Price is developing a research programme using MR and PET imaging to understand heterogeneity in brain tumours; the main focus is in studying the invasiveness of glioblastomas and understanding the biology of glioma invasion in individual patients (the MALTING Study).

Akhilesh Reddy works in the Institute of Metabolic Science on circadian rhythms in eukaryotic cells and microorganisms. Rhys Roberts works in the Cambridge Institute for Medical Research on membrane traffic and recirculating endosomes in the context of genetic disorders of peripheral nerve.

Research synopsisResearch in the department falls into three main areas with major relevance for human disease. The Haematopoiesis and Leukaemia Group are based in the Cambridge Institute for Medical Research (Professor Green, Professor Göttgens, Dr Huntly, Dr Ottersbach) and the MRC Laboratory of Molecular Biology (Professor Warren). The Structural Medicine and Thrombosis Group (Professor Read, Professor Huntington) are based in the CIMR, and the Transfusion Medicine Group (Professor Allain, Dr Lee, Professor Ouwehand, Dr Ghevaert) are based in the NHS Blood and Transplant Building. Recent research initiatives include the establishment of a $6.0m Specialist Centre for Research, funded by the US Leukemia and Lymphoma Society, the only one in Europe. The department has also played a leading role in establishing a £5.8m European Bloodomics programme.

Haematopoiesis and leukaemiaHaematopoiesis represent the best characterised adult stem cell system and continues to provide important paradigms for understanding other stem cells as well as cancer biology. The focus of this group continues to be the transcriptional regulation of blood stem cells, and the mechanisms whereby such stem cells are subverted to form leukaemias. Current research programmes include:

1 Myeloproliferative neoplasms, JAK/STAT signalling and stem cell subversion (Professor Green).

2 Transcriptional networks regulating blood stem cells (Professor Göttgens).

3 The pathogenesis of bone marrow failure syndromes and leukaemia (Professor Warren).

4 The biology of leukaemia stem cells (Dr Huntly).

5 The developmental origin of haematopoietic stem cells (Dr Ottersbach).

Structural medicine and thrombosisStructural biology gives an unparalleled insight into the molecular details of biological mechanisms, an insight that has the potential to lead to rationally-designed therapies. This is illustrated by some recent studies. Professor Huntington is studying the details of the delicate control of coagulation by members of the serpin family of serine protease inhibitors; over the past year, new insights have been gained into the control by serpins of factor IXa and thrombin. Dr Zhou is studying members of the serpin family adapted for non-inhibitory roles, with a series of structures of angiotensinogen and its complex with renin revealing a new mechanism by which oxidative stress modulates the control of blood pressure. The determination of such structures is heavily driven by computer methods, an area to which Professor Read’s group is making significant contributions.

Transfusion medicineThe focus of transfusion medicine research is in blood borne viruses, diagnostics and transfusion in resource poor areas, biology and genomics of megakaryocytes and platelets. Particular highlights include:

1 Global studies of the molecular epidemiology of Hepatitis B virus in collaboration with major blood centres around the world. The genomes of HBsAg- and HBsAg+ strains have been sequenced and analysed. (Professor J-P Allain).

2 A Genome-Wide Association Study meta-analysis which identified 15 genetic loci that regulate the volume and count of platelets and the discovery of novel genetic loci that regulate platelet function (Professor H Ouwehand).

3 A rapid low cost diagnostic test for Chlamydia trachomatis has been developed and is now widely available. A test for HBsAg is being submitted for licensing (Dr H Lee).

Research synopsisThe Division combines research, teaching and diagnostic histopathology. The research focuses on analysing the molecular and cell biology of disease and applying advances in this area to clinical histopathology, and where relevant, therapy.

The Division takes part in the teaching and examining of Pathological Sciences in Pt. Ib and Pt. II tripos as well as being responsible for the clinical pathology course at Addenbrooke's and the Final MB Part I Examination. The Division has a number of major projects, studying in particular neoplastic disease. These include the study of human tumours of the central nervous system, tumours of the lower intestinal tract, lymphomas, breast and ovarian tumours. Many of the projects are in collaboration with other research groups within Addenbrooke's or the University of Cambridge. The Division has an established tissue bank, and through this can provide researchers with well-characterised human tissue, subject to project approval by NHS R&D and NRES.

The Cambridge Brain Bank, a division of the Tissue Bank is also located in the Division and underpins a number of major projects on aging and degenerative neurological disease.

Research synopsisThe Department’s research examines mechanisms responsible for important single gene and polygenic disorders. The major areas under study include: type 1 diabetes; neurological diseases such as Huntington’s disease; hereditary spastic paraplegias; renal disorders such as renal tubular acidosis and polycystic kidney disease; X-linked intellectual disability disorders; prenatal brain growth and genetics disorders of pain sensing.

The Department currently has particular strengths in three major areas:

1 Large scale gene mapping, expression, functional, statistical and bioinformatic technologies, being applied to developing strategies for the primary prevention of type 1 diabetes in the Juvenile Diabetes Research Foundation/Wellcome Trust Diabetes and Inflammation Laboratory; and to X-linked intellectual disabilities.

2 Experimental analysis of the molecular cell biology of genetic disease, with novel disease mechanisms identified over the last two years for a number of different kidney, renal and neurological disorders.

3 Development of therapeutic strategies for brain and muscle diseases associated with intracellular aggregate formation and autophagy.

The expectation is that this research into genetic cause and mechanism will lead, in the long term, to treatments for genetic diseases.

Medical Genetics is also a major participant and contributor to the National Institute for Health Research Cambridge Biomedical Research Centre, which focuses on translational experimental medicine studies in neurodegeneration, clinical genetics, renal disease and type 1 diabetes. The Department is actively involved in two cross-cutting activities, the Eastern Sequence and Informatics Hub and the Cambridge BioResource, providing key resources for the Biomedical Research Centre.

Whilst most research is carried out in the Cambridge Institute for Medical Research the Academic Laboratory of Medical Genetics is located alongside the Clinical Department on level 6 of the Addenbrooke’s Treatment Centre. The medically qualified members of the Department also have clinical duties, and there is close interaction and joint projects between the University and NHS departments.

Research synopsisThe Department of Medicine is one of the largest in the Clinical School comprising 11 Divisions and over 400 members of staff, including 22 professors, and holding current grants in excess of £38m. The Department has an active research programme whose broad aim is to understand disease processes at the molecular level and apply this knowledge to clinical management. The thematic focus of the Department of Medicine is in the broad area of immunity, inflammation and infection, and a number of new posts are currently being appointed to increase the Department’s strength in these areas. The Department is also home to the NIHR Biomedical Research Centre Cell Phenotyping Hub, which provides state of the art flow cytometry facilities for unscreened human samples.

AnaesthesiaThe research in the Division has three main strands: The first involves physiological imaging in traumatic brain injury (TBI), at all stages, from ictus to late outcome. Positron emission tomography (PET) and magnetic resonance imaging (MRI) in the acute phase currently addresses novel mechanisms of energy failure, including diffusion hypoxia and mitochondrial dysfunction. Allied studies have addressed the mechanisms of action of novel interventions such as hyperoxia. Our late studies with 11C-flumazenil PET have shown selective neuronal loss and late diffusion weighted imaging has been used to map the extent and severity of white matter loss. Both of these subtle sequelae of TBI are missed by conventional MR imaging, and may account for the mismatch between structural lesions and cognitive outcomes. A second strand focuses on the neuro-anatomical basis of coma and consciousness, both in pathological states, and in the controlled situation of sedation induced by anaesthetic agents. Finally, the Division has a growing program in pain research that involves functional imaging, pain phenotyping and pain genetics.

Cardiovascular MedicineThe Division has assembled a collaborative group of cardiovascular investigators who collectively provide expertise in basic, translational and clinical cardiovascular research and who employ genomics, epigenetics, high throughput sequencing, biomarker identification and validation, through to novel imaging, diagnostics and experimental medicine studies to improve patient outcomes. Atherosclerosis leading to myocardial infarction (MI) and stroke is the commonest cause of death in the UK. Inflammation, cell death (apoptosis), and cell senescence in atherosclerotic plaques are major contributors to plaque rupture and MI, and cardiomyocyte apoptosis underlies heart failure. Our research examines the causes and regulation of these processes in atherosclerosis, with a particular focus on DNA damage, and more recently the role of epigenetics in human heart failure. Professor Ziad Mallat has recently joined the Division, with a major interest in immune regulation of atherosclerosis and aneurysm formation, and Dr Helle Jørgensen as a University Lecturer interested in epigenetic regulation of stem cell differentiation, to support the MRC-funded Cambridge

Cardiovascular Consortium, a network of researchers focused on cardiovascular stem cells and development.

The Division’s major clinical research interests include the diagnosis of heart failure, assessment of viability in dysfunctional myocardium, and the utility of transient ischaemia or novel therapeutics to protect the heart from further insults. We have developed metabolic cardioprotection during PCI (both primary emergency and elective intervention), examined the effect of new agents to treat diabetes on cardiac performance in type 2 diabetes, and determined the optimum use of cardiac resynchronisation therapy based on the underlying pathophysiology. As part of our unstable atherosclerosis and aneurysm programme, we have developed novel methods and ligands for imaging of unstable plaques, particularly using PET, CT and VH-IVUS, to utilise imaging for risk stratification and to monitor drug therapy. We are determining (a) whether inflammation, hypoxia and neovascularisation detected by PET/CT and MRI at baseline predict future aortic aneurysm expansion over a 3-year period: (b) the mechanism of increased cardiovascular death in patients with rheumatoid arthritis, using PET/CT to detect changes in arterial inflammation after anti-TNFalpha therapy: (c) whether a novel anti-atherosclerosis drug could reduce vascular inflammation. This was the world’s first multi-centre PET/CT vascular imaging study, conducted in collaboration with GSK.

ACF, PhD Fellowship, and Clinical Lectureships. The programme enables trainees in almost any branch of Medicine to acquire skills that bridge the bench-to-bedside divide. The division’s internal research interests are:

1 Professor Morris Brown investigates genetic and non-genetic approaches to relating pathogenesis of hypertension to finding the best treatment or cure in individual patients. Clinically, he leads the BHF’s multicentre programme of trials, PATHWAY, which will lead to the routine use of plasma renin analysis, and has validated use of 11C-metomidate for PET-CT scanning of Conn’s adenomas of the adrenal. Laboratory discoveries include the finding of somatic mutation of a K+ channel in 50% of 50 Conn’s adenomas, and the role of an orphan G-protein coupled receptor (GPCR), GPR61, in regulating aldosterone secretion.

2 Dr Anthony Davenport studies apelin and other novel G-protein couple receptors that are emerging as drug targets. He has identified apelin peptides as transmitters in the human cardiovascular system with potent inotropic and vascular actions. In collaboration with the Department of Chemistry selective agonists and the first apelin antagonists have been discovered.

3 Dr Ian Wilkinson studies large artery function and endothelial function. He holds a BHF Senior Clinical Fellowship, which centres on dissecting out the mechanisms responsible for arteriosclerosis or arterial stiffening, which underlies systolic hypertension. Thus far inflammation and calcification have been identified as important drivers of stiffness. He was recently awarded a £3m TSB grant to identify cardiovascular biomarkers in patients with COPD and test the effectiveness of two novel GSK compounds.

4 Dr Thomas Krieg investigates pathways of myocardial protection following ischaemic injury.

Diabetes & EndocrinologyThis Division has three main areas of research:

1 Dr Evans is interested in (1) how the brain detects changes in blood glucose and how this glucose-sensing interacts with peripheral metabolism, (2) how defences against hypoglycaemia may become abnormal in diabetes, (3) the effects of hypoglycaemia on the brain, and (4) improving the ability of patients with type 1 diabetes to manage their own diabetes through structured education and judicious use of new and innovative technology for monitoring and managing diabetes, including in collaboration with Dr Roman Hovorka (Department of Paediatrics) and colleagues, the closed loop insulin pump systems (the 'artificial pancreas').

2 Dr Gurnell’s research interests include (i) the role of nuclear hormone receptors in human disease, and genetic disorders of the hypothalamic-pituitary-thyroid axis, (ii) functional imaging in endocrine neoplasia, (iii) novel approaches to sparing hypothalamic-pituitary function in patients with sellar/parasellar tumours, and (iv) the endocrine and neural basis of financial decision making.

3 Professor Chatterjee’s research interests relate to disorders of nuclear hormone synthesis and action. He is studying several human cohorts: congenital hypothyroidism (CH) that is familial, syndromic or on a consanguineous background; Resistance to Thyroid Hormone (RTH); and lipodystrophic insulin resistance associated with PPARγ gene defects. Candidate gene and whole exome approaches are used to identify novel genetic aetiologies mediating thyroid dysgenesis or hormonogenesis and defective hormone action. These approaches are supported by human phenotypic studies, studies in multisystem selenoprotein deficiency disorders and translation through our national diagnostic laboratory service to develop biomarkers of hormone action and therapies applicable to commoner thyroid disorders.

Gastoenterology and HepatologyResearch in this Division focuses on immunity and inflammation and its consequences, and the genetic underpinning of gastrointestinal diseases.

1 Professor Kaser’s group has a research focus on inflammation at mucosal body surfaces and inflammatory bowel disease (IBD). Specifically his group investigates the role of the intestinal epithelium at the interface between the intestinal microbiota and the sterile host environment, with a particular interest in the epithelium’s endoplasmic reticulum stress response.

2 Dr Parkes investigates the genetic basis of IBD through genome-wide association studies (GWAS) performed in collaboration with the Wellcome Trust Sanger Centre. He has also been leading the International IBD Genetics consortium’s GWAS meta-analysis, which revealed almost 100 distinct genetic loci associated with IBD.

3 Dr Fitzgerald (based in the MRC Cancer Cell Unit) investigates the molecular pathogenesis and progression of Barrett’s disease and oesophageal cancer to provide tools for early diagnosis, accurate prognostication and therapy which can be applied to clinical practice.

4 Further research topics covered in the Division are on chronic liver disease (Dr Alexander), liver transplantation (Dr Gimson), small bowel transplantation (Dr Middleton and Dr Woodward), non-alcoholic fatty liver disease (Dr Allison) and inherited liver disease (Dr Griffiths). In translational research, multi-centre trials of novel biological therapies for IBD, which target specific immune functions, are pursued within the Division.

ImmunologyWork in the Division of Immunology covers three mains areas:

1 The Fearon lab has shifted its interest from the memory CD8+ T cell to tumor immunology. The immune system should be able to control the growth of many tumors because cancer cells with genomic instability generate neoantigens, which serve to make them appear as 'foreign' to the immune system. However, this obviously does not occur. One problem appears to be that the tumor microenvironment is immune suppressive, so that the systemic T cell responses to tumor antigens that can be demonstrated are prevented from

attacking the cancer cells. Our lab has recently shown that one type of tumor stromal cell (ie. a cell in tumors other than the cancer cell), the FAP+ cell, mediates local immune suppression, and its elimination allows immune control of tumor growth. We have also found that the FAP+ cell resides in normal tissues where it has unexpected functions, such as the prevention of cachexia, the muscle wasting syndrome often associated with cancer. We wonder whether the biological role of the FAP+ cell is related to tissue maintenance and repair, accounting for its regrettable presence in tumors? We are trying to discover how to interrupt the immune suppressive function of the FAP+ stromal cell.

2 The Griffths lab studies cytotoxic T lymphocytes (CTL) and Natural Killer (NK) cells, which use polarised secretion to destroy virally infected and tumorigenic target cells. Specialised secretory lysosomes, containing the pore forming protein perforin and a series of serine proteases, termed granzymes deliver the lethal hit in a specialised domain of the immunological synapse. The research is focused on understanding the molecular basis of polarised secretion from CTLs and has used a series of rare genetic diseases including Hermansky-Pudlak and Haemophagocytic syndromes to identify the roles of proteins involved in secretion from CTL and NK cells.

3 The Lehner lab studies mechanisms used by viruses to evade immune recognition, with a particular interest in the role of ubiquitin in receptor regulation. While initially focusing on viral evasion of MHC class I molecules, they recently developed a quantitative proteomics technique termed ‘plasma membrane profiling’ which takes an unbiased approach to analyze how viruses alter expression of any cell surface receptor to enable their replication. This powerful approach has identified novel immune as well as metabolic receptors, such as transporters downregulated by latent human cytomegalovirus infection (collaboration with Prof John Sinclair), and is now being used to interrogate cell surface receptor regulation by several different intracellular pathogens.

Infectious DiseasesInfectious diseases research encompasses basic studies on viruses, bacteria and host immune responses.

1 Professor John Sinclair’s group studies how human cytomegalovirus (HCMV) persists in healthy individuals studying cellular factors which control virus latency and reactivation. In collaboration with Professor Sinclair, Professor Sissons and Dr Wills’ group study the control of HCMV infection by the immune system. They have shown dendritic cells to be a major site of HCMV carriage. More recently the group has defined novel viral immune evasion molecules.

2 Professor Lever’s group studies retroviruses, including structural and molecular studies of RNA and RNA:protein interactions involved in genome encapsidation and the development of gene vectors. He and Dr Desselberger are investigating rotavirus RNA structures involved in encapsidating the viral genome and which host cell proteins or organelles may interact with the virus and be involved in viral assembly.

3 Dr Nejentsev’s group investigates the genetic basis of susceptibility to mycobacterial infection and tuberculosis (TB). Discovery of such genes will help to understand mechanisms of resistance to infection and may point to new targets for therapeutic intervention. The group is part of the TB-EUROGEN consortium. In collaboration with the Wellcome Trust Sanger Institute they are performing a genome-wide association study aiming to discover genomic regions associated with TB.

4 Professor Sharon Peacock’s group aims to introduce high-throughput whole genome sequencing technologies into diagnostic and public health microbiology collaborating with the Wellcome Trust Sanger Institute and the Health Protection Agency. Proof of principle will be achieved by developing a system to track transmission of, methicillin resistant Staphylococcus aureus (MRSA) in real-time. This technology will subsequently be extended to other important human pathogens.

Metabolic MedicineProfessor Cox’s group studies the molecular pathogenesis of lysosomal diseases with particular emphasis on the development of effective treatments – he gave the inaugural lecture at the first Gordon Conference on Lysosomal Diseases in 2011. With Dr Deegan, Clinical Director of the National Centre for the Treatment and Diagnosis of Lysosomal diseases, several clinical trials of substrate reducing drugs, pharmacological chaperones and innovative enzyme therapies are underway, particularly for Gaucher’s disease and Fabry disease. Dr Stein, in collaboration with Professor Read, has been analysing the 3-dimensional structure of mutant and therapeutic-lysosomal proteins to understand the consequences of the disease-related changes and their susceptibility to therapeutic molecular manipulation – pharmacological chaperones. Dr Marchesan conducts studies of the molecular targeting and delivery of lysosomal proteins to their sites of action. With Dr Pavlova, there are studies to investigate the predictive role of cytokine biomarkers for the development of the much-feared bone complications in Gaucher disease; in a cross-sectional collaborative in more than 100 patients with Gaucher disease, we have found that those with a history of sporadic infarction events have higher serum cytokine biomarkers, which respond to enzymatic therapy. With other investigators in a European Framework Package 7 (FP7) award 'EUCLYD' Dr Pavlova is investigating novel inhibitors of sphingolipid in a tissue–specific and inducible experimental model of Gaucher disease. These studies should reveal much about the molecular pathogenesis of the osseous complications and further define the relationship between defined cytokines and disease manifestations. Dr Cachón-González and Dr Sargeant study the molecular pathogenesis of the emblematic neurodegenerative storage disorder, Tay-Sachs disease. Overall the group has been central to the formation of an International Tay-Sachs disease Gene Therapy Consortium to translate successful gene therapy conducted in murine models into a viable therapeutic agent for use in man. These studies can be applied clinically and offer the opportunity for a unique understanding of the molecular pathogenesis of disorders affecting the metabolism of complex glycosphingolipids.

Renal Medicine1 Professor Smith’s group is based in the CIMR, and works

on immune regulation and autoimmune and inflammatory disease. This has focused on how naturally occurring variants in immune molecules such as FcγRIIB alter immune function and predispose to autoimmunity. The accumulation of these risk variants in the population has been shown to be, at least in part, due to their ability to protect against infections such as malaria. With Dr Lyons and in collaboration with Addenbrooke’s Vasculitis & SLE Clinic and the Division of Gastroenterology, Smith runs a translational programme studying the pathogenesis of human disease at the same time as looking for biomarkers. A CD8T cell transcriptional signature has been found which predicts prognosis in autoimmune disease. The European Vasculitis Genetics Consortium is also led from the laboratory.

2 Dr Clatworthy studies immunological mechanisms of renal injury, in particular in areas of acute tubular necrosis and transplantation, using cutting-edge imaging technology.

3 Dr Jayne runs the Vasculitis & Lupus clinic, and coordinates multi-centre trials in vasculitis and SLE. These are focused on the evaluation of new agents and the optimization of conventional therapies. His group recently coordinated a study contributing to the DFA approval of Rituximab for use in the therapy of vasculitis. He coordinates the European Vasculitis Study Group which forms clinical trials and long term evaluation of vasculitis patients.

4 Dr Bradley’s group has been studying the pathways involved in signaling by TNF-alpha family members in endothelial cells and their relevance to renal inflammation and transplant rejection. He coordinates the Yale-Cambridge Cardiovascular Research Initiative, and is the Director of the NIHR Cambridge Biomedical Research Centre.

Respiratory MedicineThe Respiratory Medicine Division has six main areas of research: granulocyte cell biology and trafficking, the structure and function of alpha1-antitrypsin and related serpins, the genetic and molecular basis of pulmonary hypertension, the immunopathology of allergic diseases, the control of antigen processing by dendritic cells and the molecular mechanisms of ER stress.

1 Professor Chilvers’, Dr Condliffe’s and Dr Parfrey’s interests relate to granulocyte cell biology, in particular, mechanisms underlying neutrophil priming, activation and apoptosis. The group also has an interest in TNFα and hypoxia signaling and neutrophil and eosinophil trafficking in vivo.

2 Professor Lomas’ group works on the pathobiology of alpha-1-antitrypsin deficiency and the serpinopathies. They are also interested in the identification of genetic factors and protein biomarkers that relate to components of the COPD phenotype.

3 Professor Morrell’s group is studying the molecular mechanisms leading to the development of idiopathic pulmonary arterial hypertension (PAH). In particular, his laboratory has elucidated the ways in which mutations in the bone morphogenetic protein type II receptor (BMPR-II), which underlie the majority of cases of familial PAH, disrupt intracellular signaling and proliferation of pulmonary vascular cells.

4 Dr Ewan’s, Dr Clark’s and Dr Nasser’s research interests are in the clinical and immunological aspects of food allergy, anaphylaxis and asthma and novel approaches to desensitization with particular reference to nut allergy.

5 Dr Floto’s group works on the molecular basis of antigen processing by dendritic cells and macrophages and how this influences the host responses to bacterial and mycobacterial infection.

6 Dr Marciniak’s group studies the role of endoplasmic reticulum stress in human disease, including malignant mesothelioma, using both tissue culture and Drosophila model systems.

RheumatologyResearch in this division covers the basic mechanisms underlying inflammatory arthritis and metabolic bone disease, together with development and validation of novel biomarkers which can be used to predict clinical outcomes.

1 Prof Gaston and Dr Goodall study the immunologic basis of inflammatory arthritis, and the factors which influence differentiation of pro-inflammatory T lymphocytes, particularly the role of dendritic cells in integrating signals from pathogens and cellular stress to alter cytokine production.

2 Dr Hall is investigating biomarkers in connective tissue diseases, including lymphocyte phenotype, novel measures of hand ischaemia, and assessment of the micro-circulation using haemoglobin video microscopy.

3 Dr Busch’s group studies the biochemical mechanisms that link genetic variants of antigen-presenting MHC molecules to autoimmune pathogenesis, focusing on the characterisation of allelic differences in MHC protein turnover, their mechanistic basis and immunological consequences.

4 Prof Compston’s laboratory combines clinical and laboratory studies in osteoporosis. Recent work includes bone histomorphometric study of age-related changes, the relationship between regional skeletal blood flow and osteoblast activity in postmenopausal osteoporosis or renal bone disease, and study of the incidence, skeletal location and underlying risk factors for fragility fracture in the obese population.

5 Dr Poole's group applies novel imaging techniques to investigate human bone diseases. With the Engineering for Clinical Practice team of Graham Treece and Andrew Gee, they have studied focal thinning as a cause of femoral neck fracture and have discovered that bone building drugs have targeted effects at key sites within the osteoporotic femur.

Research synopsisThe Department of Obstetrics and Gynaecology has programmes of basic, translational and clinical research addressing the determinants of pregnancy complications. Dr Charnock-Jones, Dr Constancia and Dr Colucci use transgenic mouse models to identify key genes involved in murine placentation with the aim of better understanding normal reproductive function. Dr Charnock-Jones studies the effect of oxygen on endothelial cells and trophoblast in the placenta. Dr Constancia has a major interest in placental epigenetics, in particular genomic imprinting (ie. selective epigenetic silencing of genes according to parent of origin). Dr Colucci aims at understanding how immune cells impact on reproduction, cancer and transplantation.

Other basic work in the department addresses preparative changes in gene expression in the fetus for post-natal life. The major focus of translational research in the Department is a prospective cohort study of women in their first pregnancy, which will have recruited 3500–4000 women by the end of 2011

and is funded by the NIHR Cambridge Comprehensive Biomedical Research Centre. The project has created a central resource of data, blood samples taken throughout pregnancy, and samples of placenta obtained at birth. The resource will be used to understand better the role of the placenta in determining adverse pregnancy outcome and, it is hoped, to identify novel biomarkers which may be clinically useful. A major focus of this research will involve the application of next generation sequencing to these samples, with a particular focus on the epigenetic regulation (methylation, histone modification and non-coding RNA) of placental gene expression. These studies involve close collaboration with the University’s Centre for Trophoblast Research (www.trophoblast.cam.ac.uk). Finally, clinical research in the Department uses secondary analysis of diverse data sources to study determinants and predictors pregnancy outcome.

Research synopsisSince 1998, we have developed a new Centre for cancer research in Cambridge. Our aim is to provide a nucleus of clinical and laboratory research that can interface with research across the University and science parks, and bring the combined expertise of Cambridge to practical application within the hospital. The Cancer Centre is a virtual organisation which provides a framework (and pump priming funds) to encourage cancer-related collaborations across disciplines, especially between biology, medicine and the physical sciences.

It is based on the University Department of Oncology, whose activities are reported here, but contains other substantial components: (1) the Cancer Research UK Cambridge Research Institute, opened in 2007, which when complete will contain over 30 research groups; (2) the MRC Cancer Cell Unit opened in 2001, which shares the Hutchison/MRC Research Centre building with the Department of Oncology; (3) the Strangeways Research Laboratories for Genetic Epidemiology, which involve close collaboration between Oncology and Public Health in studies of cancer susceptibility; (4) a new Clinical Trials Centre within the hospital.

Our aim is to create an environment in which individual research ideas can flourish, supported by the necessary clinical infrastructure. Nevertheless, to build the Centre, we have had to specify some focus. Within Oncology, we have set up programmes around selected cancer sites, that will span from basic biology to clinical application and which will act as a framework with which science across the Clinical School and University can interact. Currently, these cancer sites are breast, prostate, pancreas and ovary, with additional programmes under development in lung cancer. Infrastructure and interactions are shared with established programmes in haematological cancers (within the Cambridge Institute for Medical Research) and in oesophageal cancer (within the MRC Cancer Cell Unit). Laboratory research themes include epithelial cell biology, gene regulation, DNA repair and checkpoint function, and there are strong programmes in molecular imaging, genomics, computational biology, drug discovery, and animal models of cancer. These biological and technological resources underpin a further major clinical programme in experimental cancer therapeutics.

In the past two years research in the Department of Oncology and the CRUK Cambridge Research Institute has contributed significantly in several fields. For example, in breast cancer we have identified proteins that are required for the oestrogen receptor to bind the DNA and induce transcription. One such protein is FoxA1; inhibitors of FoxA1 binding may provide a therapeutic approach to breast cancer which is resistant to endocrine deprivation. In a separate collaborative study of 1000 women from whom we have frozen breast tumour material and clinical data with a median 10 year follow-up, we have completed a genome-wide analysis of copy number variation and of gene expression, which has provided a far more detailed molecular subclassification of breast cancer than was previously available, with new insights into personalised approaches to treatment. In pancreatic cancer, we have shown using transgenic mouse models that resistance to the commonly used drug gemcitabine may result from poor penetration of the drug into the tumour because of the dense surrounding stroma. Experimental data suggest that combined use of a drug targeted at the stroma may improve treatment outcome: an idea that is now being tested in the clinic. In prostate cancer, our 100,000-strong cohort of men who have had PSA testing as part of a study of the management of the early disease, has provided low-PSA controls for successful genome-wide association studies, which have identified a majority of the prostate

cancer susceptibility loci so far identified. Further investigation of one of these loci has yielded a protein biomarker, MSMB, which may provide a better, and urine-based, marker for detection of significant early disease than PSA.

Research synopsisThe Department's research is in four main areas: genetic and hormonal control of human sex development; genetics and pathophysiology of diabetes; the determinants of birth size and infant growth; critical illness endocrine physiology.

Studies on mammalian sex development are applied to the management of infants with disorders of sex development (DSD), including the effects of environmental chemicals, which may

disrupt endocrine control of fetal development. Polymorphic variants in genes controlling androgen production and action appear to affect normal development, including growth at puberty. Much of this research is underpinned by the Cambridge Baby Growth Study (CGGS) established by Professor Hughes in 2001 and now celebrating its 10th Anniversary, with over 2000 families recruited. A major component of CBGS studies, directed by Dr Ken Ong at the MRC Epidemiology Unit, is now focusing on nutrition and how early feeding practices influence risks of obesity and age of onset of puberty. This unique resource is spawning collaborative studies across several specialties in the Cambridge Biomedical Campus. In 2008 Professor Dunger and his team launched the first international study of the use of ACE inhibitors and statins in adolescents with Type 1 diabetes (T1D). Ongoing studies on T1D include the role of the growth hormone – IGF1 axis in insulin resistance, and the place of growth hormone inhibitors in preventing diabetic complications.

Clinical testing of closed-loop insulin delivery in T1D developed by Dr Hovorka is showing promising results. Under supervised conditions, overnight closed-loop reduced the risk of nocturnal hypoglycaemia and improved glucose control. First ever home testing will adopt an in-house prototype system which has received regulatory approval. The physiology of survival and late morbidity as a consequence of acute life-threatening or critical illness is being studied by examining the effects of stress endocrinology and hyperglycaemia. The successful Neonatal Insulin Replacement Therapy in Europe (NIRTURE) study is being extended to early childhood to determine the role of insulin and glucose control on long term risk of glucose intolerance in later life.

Research synopsisThe Department boasts the highest quality psychiatry research in the UK, with 80% of research rated as being 4* or 3* (world-leading or internationally excellent) in the Research Assessment Exercise 2008.

Research in the Department is focused on major disease areas using a range of investigative techniques. Developmental paradigms are central in much of the Department's work from the point of view of pathological states, life course models of adult health and the application of novel statistical techniques.

Contemporary neurobiological techniques such as structural and functional MRI, neuro-endocrinology, cognitive psychology and molecular genetics are used to characterize large, epidemiologically principled or longitudinal samples as well as to elucidate drug models of disorders and their treatments in smaller scale, more mechanistic studies. There are cognate methodological strengths in many of these techniques, especially epidemiology neuroimaging, cognitive psychology and psychopharmacology. The full gamut of translational clinical research is an increasing focus. Research activity in the Department benefits from a wide range of national and international collaborations including leadership roles in the MRC/Wellcome Trust Behavioural & Clinical Neurosciences Institute, the NIHR Collaboration for Leadership in Applied Health Research and Care (CLAHRC) for Cambridgeshire and Peterborough, a Wellcome Trust Strategic Award for Neurosciences and Mental Health and the GSK Clinical Unit.

Research synopsisThe Department of Public Health and Primary Care at the University of Cambridge is one of the UK's leading university departments of population health sciences, top-ranked in Epidemiology and Public Health in the Research Assessment Exercise 2008.

The department has been led since 2001 by Professor John Danesh and consists of over 330 staff and postgraduate students. The overall research mission is to generate scientific evidence that will inform the prevention of premature death and disability, particularly in relation to common chronic conditions such as cardiovascular disease, common cancers, dementia, diseases of ageing, osteoporosis, and metabolic diseases. The goal is to translate this evidence into the development and evaluation of preventative interventions.

Key strategies involve investigations of the separate and combined influences of genetic and environmental factors in chronic diseases by studies of several in-house epidemiological collections and of large-scale collections established through national and international collaborations. In several of these studies, aetiological investigations and patho-physiological natural history studies are integrated with molecular biology and clinical medicine. Understanding of the determinants of disease and behaviour change are then utilised in the development and evaluation of interventions at individual and population levels. There is also research into methods of study design, development of interventions and biostatistical analyses.

The Department has recently made senior appointments, including Professor Theresa Marteau (Director, Policy Research Unit, 2010) and Professor Simon Thompson (Director of Research in Biostatistics, 2011). Further examples of major developments in recent years include:

1 establishment of major research initiatives in developing countries, especially in South Asia, such as the Pakistan Risk of Myocardial Infarction Study and partnership in the Public Health Foundation of India-UK Consortium from 2008

2 establishment of the MPhil course in Public Health in 2006, and co-direction of a new four-year inter-disciplinary PhD programme in cardiovascular research supported by the British Heart Foundation from 2009

3 establishment of a new Department of Health funded Policy Research Unit in 2010

4 leadership of international customised gene array consortia in cancer ('iCOGs') and in vascular disease ('metabochip+').

Research synopsisThe research activity of the department spans a wide range from molecular imaging developments at a 'bench' level, through novel imaging technique development to clinical studies of new imaging applications. These activities involve numerous multi-disciplinary collaborations across the Campus and the wider University, including links with Engineering, Physics, Medical Physics, the CRUK Cambridge Research Institute and the major themes of the NIHR Cambridge Biomedical Research Centre of which Imaging forms a key cross-cutting theme.

The department benefits from access to an extensive portfolio of modern imaging equipment including advanced colour

Doppler Ultrasound, 1.5T and 3T MRI and MRS, 16, 64 and 128 detector and dual energy CT as well as PET-CT and advanced radiochemistry. There are close research links with the Neurosciences utilising CT, MR and PET techniques in studies involving stroke and carotid disease in particular. Multiple new clinical trials in Oncology have been established, investigating both new imaging based biomarkers and the evaluation of new therapeutic agents in early phase 1 trials. A particular focus of current and future work has been molecular imaging with the development of gene reporter techniques as well as hyperpolarised 13C agents and related imaging applications in collaboration with the CRI and Biochemistry.

Individual groups have undertaken research in the identification and characterization of vulnerable plaque, the improved definition and characterization of brain tumours, the development of new interactive real-time techniques for paediatric and neonatal MRI, the development of non-contrast enhanced 3D vascular imaging techniques, the clinical applications of ultrasound and MR based elastography for malignant lymph node detection and focal liver lesion characterisation. Our previous work on the impact of imaging techniques on clinical decision making continues to be cited in national guidelines, notably involving breast cancer and chest disease management.

Research synopsisThe Department of Surgery has a strong clinical emphasis and the overall research strategy is to improve the surgical management of disease through developments in both basic and translational research. There is a major focus on applied clinical research and a key feature of the department is the close integration of University and NHS surgeons. University surgeons in parallel with directing programmes of research play an important role in the development and delivery of specialist surgical services. Similarly, many NHS surgeons are, in addition to their clinical responsibilities, undertaking high quality clinical research supported through close collaboration with University colleagues. In contrast with the trend in many other UK universities, academic surgery in Cambridge is flourishing and the department continues to expand. The principal research interests are transplantation, stem cell medicine, surgical oncology and orthopaedic surgery. In addition, clinical research of international importance is being led by NHS surgical colleagues across a range of surgical disciplines, including ear, nose and throat surgery, ophthalmic surgery, gastrointestinal surgery and vascular surgery.

TransplantationThe Division of Transplantation, directed by Professor Bradley, has been at the international forefront of clinical developments in organ transplantation for many years and the world-renowned clinical programmes in abdominal organ transplantation based at Addenbrooke’s, and thoracic organ transplantation based at Papworth Hospital NHS Foundation Trust, are each underpinned by well-established multidisciplinary research programmes. Research ranges from basic molecular and cellular immunology to translational research and evaluation of new technologies. The Division includes the Transplantation and Regenerative Medicine Theme of the NIHR Biomedical Research Centre. There are strong programmes of basic research into the molecular basis of allograft rejection, with a particular focus on the role of B cells and alloantibody in acute and chronic rejection, interactions between endothelial and immune cells in allograft vasculopathy, molecular mechanisms underlying the induction and maintenance of immunological tolerance, and analysis of physicochemical properties determining the immunogenicity of HLA molecules. The division is undertaking, a number of investigator led single and multi-centre clinical research programmes aimed at evaluating novel immunosuppressive agents, extending donor organ use and minimising organ injury prior to transplantation. Senior investigators in the department are also working closely with scientists and statisticians in the Division of Organ Donation and Transplantation at NHS Blood and Transplant to maximise the outcome of organ transplantation in the UK.

Stem Cell MedicineProf Roger Pedersen’s and Dr Ludovic Vallier’s groups are conducting research into the early stages of embryonic stem cell differentiation and the genetic mechanisms responsible for these processes. Both mouse and human embryonic stem (hES) cells are being studied, and interfering (si)RNAs are being used to modify gene function and examine the role of specific genes, with the aim of ultimately controlling differentiation into specialised cell types for potential therapeutic use. Research is also being undertaken into the mechanisms responsible for the maintenance of pluripotency in hES cells and the formation of mesodermal and endodermal cell lineages, as well as the epigenetic stability of pluripotent stem cell lines. Both groups interact extensively with other leading investigators within and outwith the University; both are key contributors to the Cambridge Stem Cell Initiative, which aims at biomedical translation of stem cell and regenerative medicine research. Both Prof Pedersen and Dr. Vallier are founding members of the School of Clinical Medicine’s Anne McLaren Laboratory for Regenerative Medicine (LRM). The LRM has played a key role in the Cambridge Stem Cell Initiative by serving as the Clinical School host for the MRC Centre Centre for Stem Cell Biology and Regenerative Medicine, which together with the Wellcome Trust Centre for Stem Cell Research on Tennis Court Road constitute the hubs of the Cambridge Stem Cell Initiative. In 2009, Dr Vallier established the human induced pluripotent stem cell Core Resource, with support from the National Institute for Health Research Cambridge University Hospitals NHS Trust Biomedical Research Centre. During the past two years, the hIPSC Core Facility has derived more the 400 hIPSC lines from 60 patients suffering from neurodegenerative diseases, cardiovascular syndromes,

metabolic and blood disorders. In parallel, the hIPSC Core Facility has become a major training centre by accommodating more than 20 visiting scientists and by supporting the development of similar platforms in several European countries.

Surgery

Orthopaedics (Department of Surgery)The Orthopaedic Research Unit, directed by Professor Neil Rushton, has a novel programme of fundamental and translational research in bone and joint repair using in vitro and in vivo approaches.

The basic science programme is designed to elucidate the developmental cascade of the osteoblast and chondrocyte lineages, both from known precursors and novel sources, and to understand their interaction with normal and newly developed matrices. Understanding how local niches impinge on the developmental cascade is a new theme. In addition to investigations on the developmental cascade there is an ongoing programme investigating the damage /repair response of the osteochondral unit.

In collaboration with the Departments of Materials Science and Engineering we are evaluating the interactions of human cells and in particular mesenchymal stem cells with collagen-based materials for the regeneration of cartilage, meniscus and tendon. With the Department of Chemistry we are using nuclear magnetic resonance spectroscopy to investigate chemical signatures within bone matrix and between the matrix and mineral phases of bone.

Translational research has resulted in the CE marking and first in man trials of an osteochondral repair product following development work carried out in the Unit. The clinical use of bone substitute materials in impaction grafting has been supported by research on the mechanical properties of mixtures of bioactive ceramic and bone.

Surgical Oncology

The uro-oncology division, directed by Professor Neal, is closely associated with the Departments of Oncology and Surgery. Cambridge has the largest robotic prostatectomy programme within the NHS and this, together with other clinical trials has allowed the development of a well-annotated bio-repository. Neal is one of the three PIs on a major NIHR funded trial (ProtecT) to determine the best treatment for men with early prostate cancer and is the largest ever surgical trial in prostate cancer. Collaborative genetic research continues with Strangeways and the ICR in London.

There is a large translational research programme involving Gnanapragasam and experimental medicine studies including imaging led from the Cambridge Research Institute where Neal is group leader. Following studies of SNPs in prostate cancer, novel biomarkers have been developed. The majority of the work in the CRI is focused on androgen receptor signalling where we have discovered novel binding sites and functionally important therapeutic targets.
