The current research areas/groupings are:
i. Bone marrow failure and related disorders
The principal research interest of Professor Inderjeet Dokal, Dr Hemanth Tummala and Professor Tom Vulliamy is bone marrow failure (BMF) focusing on the genetics of the inherited BMF syndromes, particularly dyskeratosis congenita (DC). Their research has highlighted the important role of telomeres in humans and the consequences of telomere dysfunction including dysregulated human development, premature ageing, increased risk of BMF and cancer. Current research is focused on elucidating the biology of the many uncharacterized cases of DC, BMF, familial myelodysplasia/leukaemia (with Drs Amanda Walne, Upal Hossain, Mohsin Badat, Ana Rio-Macin and Professor Jamie Cavenagh) as well as studies aimed at correction of the primary cell defect with the long term aim of developing new therapies for these patients.
ii. Brain tumours and neural stem cells
Professors Silvia Marino, Denise Sheer and Dr Sara Badodi have developed a systematic strategy to identify critical genetic, epigenetic and gene expression features in brain tumours. Key discoveries include RAF fusions in pilocytic astrocytomas, microhomology at the RAF fusion breakpoints, MYB abnormalities in certain grade II astrocytomas (Sheer) and the identification and elucidation of the role of PcG group genes in medulloblastoma and high grade glial tumours (Marino). Ongoing studies include exome/genome sequencing, DNA methylation and histone mark profiling with a view of understanding the neural stem cell as cell of origin of brain tumours and identifying novel targets for treatment via studying the basic biology of brain tumours.
Dr Sindhuja Sridharan is a systems biochemist who is interested in understanding how alterations in molecular interaction networks of proteins are wired in physiology and disease, particularly brain tumours.
iii. Children’s environmental health and respiratory disease
Professor Jonathan Grigg and Dr Abigail Whitehouse’s environmental research is focused on our local population. The “Exhale” study is measuring changes in lung function and biomarkers of exposure to air pollution in primary school children over a 5 year period–coinciding with the introduction of the London low emission zone. Laboratory studies are assessing the mechanisms underlying the increased vulnerability to pneumococcal pneumonia in children exposed to particulate air pollution. In our NHS patient’s research is focused on treatment of preschool wheeze, difficult asthma and the prevalence of obstructive breathing in patients with sickle cell disease (in collaboration with Professor Paul Telfer).
iv. Colorectal cancer and inflammatory bowel disease
The major interest of Professor Andrew Silver and Mr Mohamed Thaha is colorectal cancer. This includes the identification of susceptibility genetic variants and modifiers of colorectal cancer (CRC) severity, and use of biomarkers of risk and outcome to facilitate stratified management in the clinic. Current studies are focussed on early onset CRC and the potential mechanistic links between type 2 diabetes and the risk of developing CRC. The genomics approach is also being applied to other types of gastro-intestinal cancers including oesophageal cancer with Professor David Kelsell. In collaboration with Professor James Lindsay the colorectal team have a strong programme of research in inflammatory bowel disease (IBD). This includes the identification of tissue and serum-based biomarkers for early detection of lesions in ulcerative colitis and fibrosis in Crohn’s disease. The group is also investigating the use of specific Histone deacetylase inhibitors for use in IBD control.
v. Developmental alterations in Down syndrome
Identification of molecular pathways altered by trisomy 21, leading to new insights into biology of Down syndrome (DS) is the long term research theme of Professor Dean Nizetic and Dr Jurgen Groet. This team identified the deregulation of embryonic stem cell fate and a new concept explaining how this de-regulation could be responsible for the increased leukaemia risk in DS children. This team also generated the first induced pluripotent stem cells (iPSCs) within the Blizard Institute, establishing a unique isogenic DS iPSC model.
vi. Diabetes and obesity
Professor Graham Hitman and Dr Elena Bochukova’s principal research is on genomics (genetic and epigenetic) of diabetes and obesity. They are part of the wider Barts diabetes and obesity research group. The Bochukova group is studying the role of chromatin regulation and deregulation in obesity related human tissues, as well as the role of obesity-associated genome variation using stem cell-derived genome-edited models and genomics technologies; this work interfaces with Hitman, Finer and van Heel. Prof Hitman together with Prof Sarah Finer’s (Primary Care and Public Health) research interest is directed to people from South Asia focussing on genomics and prevention strategies in high risk populations. For example one current program includes genomic and lifestyle predictors of foetal outcome relevant to diabetes and obesity in South Asians living in Europe or their home countries. This work also has a complementary interface with other investigators in the Centre (Professors Vardhman Rakyan and David van Heel) and that of Primary Care and Public Health
vii. East London Genes and Health
Professor David van Heel currently leads this large exciting programme. He has also had a research interest in human autoimmune diseases (Coeliac disease, type 1 diabetes and Crohn's disease), and the functional consequences of genetic variants on human biology. Significant discoveries have included the identification of 40 new risk variants for coeliac disease, understanding the overlap between autoimmune diseases, and probing the role of rare variants. Professors David Van Heel and Richard Trembath established (initially through a Wellcome Trust Strategic Award) the East London Genes and Health programme to determine the genetic variants important in health and disease at the population level and which has relevance to common diseases such as diabetes. This programme has grown significantly over the last 5 years and now has a large number of national and international collaborators and projects.
viii. Epigenetics
The overall goals of the groups led by Professor Vardhman Rakyan, Doctors Miguel Branco, Ana O'Loghlen, Yung-Yao Lin, Pradeepa Madapura, Diega Villar and Radu Zabat are to understand the molecular basis of the non-genetically determined component of mammalian phenotypes and diseases.
Within this context the Rakyan group has a particular interest in ‘epialleles'–loci at which the epigenetic state varies as a result of stochastic, genetic and/or environmental influences. Several complementary lines of investigation are pursued to integrate molecular genomics, computational biology, mouse models, and human cohorts to understand the role of epialleles in complex phenotypes and diseases, transgenerational epigenetic inheritance, and environmental epigenomics.
The Branco group is investigating DNA methylation as well as its enzymatic oxidation derivatives (e.g. hydroxymethylation) with a particular interest in the targeting of retrotransposable elements by epigenetic modifiers and how this impacts on the host’s genome.
The O’Loghlen group is investigating the role of the epigenetic complex PRC1 (Polycomb Repressive Complex 1) in repressing important tumour suppressors such as the INK4a/ARF locus. There is also interest in the function of PRC1 components, in particular the polycomb protein CBX7, in maintaining stem cell pluripotency and inducing cellular differentiation.
The Madapura lab is investigating the role of chromatin proteins and histone modifications in the regulation of gene expression. His lab uses state-of-the-art methodologies to identify regulatory elements (e.g. enhancers), how enhancers function in normal development and how noncoding mutations contribute to disease.
The Villar lab is investigating the molecular mechanisms underlying transcriptional dynamics in mammals, and how their alterations can lead to disease states in humans. To address these questions, our work takes an integrative approach by combining functional genomics, bioinformatics and genetic perturbations across various models of the mammalian myocardium.
The Zabet group combines computational biology and molecular biology to develop new mechanistic models of how gene regulation works and its interplay with 3D gene architecture and epigenetic factors.
ix. Global Child Health Research and Infection
Professor Andrew Prendergast and Drs Claire Bourke and Melanie Smuk have a focus on the interaction between infection, immunity and malnutrition, particularly in the context of HIV infection. Specifically, the group is investigating the role of microbial translocation, a pathological process that underlies two conditions of global public health importance: childhood malnutrition and HIV infection. Laboratory investigations of the causal pathway linking poor sanitation/hygiene and impaired growth in infancy and the link between the gut microbiota and growth are being explored.
Dr Robin Basu Roy is also part of the paediatric infection research programmes with a focus on TB and special interest in complex/resistant cases.
Professor Aine McKnight’s research group has had a longstanding focus on the interface between viruses and the immune system with regard to adaptive humoral and innate (intrinsic) immunity. Her group has made seminal advances in the context of HIV and more recently SARS-CoV-2.
x. Haemoglobinopathies
Professor Paul Telfer (together with clinical colleagues including Dr Banu Kaya )are undertaking a range of interventional studies in patients with sickle cell disease and thalassaemia. This includes novel cell and drug therapies.
xi. Neonatal medicine
The major emphasis of neonatal research has been the study of determinants of adverse outcomes following extremely preterm birth. This has involved long term collaborations between Professors Kate Costeloe and Naraendra Aladangady and other institutions. Other areas include the role of probiotics and microbiome (Professor Narendra Aladangady, Drs Shahid Hussain and Paul Fleming) in prevention of complications of prematurity in collaboration with the Dept of Microbiology in Barts Health, the use of Doppler ultrasound to study the neonatal circulation, particularly in relation to necrotizing enterocolitis (Drs Steve Kempley and Ajay Sinha), mechanisms of placental transfer of nutrients, retinopathy of prematurity (Drs Shahid Husain, Ajay Sinha) and hypoxic ischaemic encephalopathy (Professor Divyen Shah).
xii. Neuromuscular disorders
Professor Marino’s group is interested in the biology of the adult skeletal muscle stem cells and progenitor cells, on the pathways and genes involved in control of their maintenance, proliferation and differentiation, in particular the Polycomb group genes (PcG). We are particularly interested in assessing how fine tuning of the expression of these genes can be exploited to enhance the regenerative function of the skeletal muscle in chronic neuromuscular disorders. Dr Yung-Yao Lin's group is investigating the molecular and cellular mechanisms underlying allelic variants of muscular dystrophies, focusing on the key components of the dystrophin-associated glycoprotein complex (DGC) and genetic modifiers of the DGC. Current research strategies have employed cellular reprogramming and genome editing technologies with the long-term aim of developing new therapeutic interventions.
Prof Marino and Dr Lin collaborate on a project aiming at applying PcG gene modulation to Duchenne Muscular Dystrophy.
