Genetics of inherited cardiovascular disease: Using molecular genetic analysis of cardiovascular disease as a tool to define disease mechanisms and therapeutic targets.

Project Description

Using molecular genetic analysis of cardiovascular disease as a tool to define disease mechanisms and therapeutic targets.

I have had a longstanding focus on inherited heart muscle diseases, in particular hypertrophic cardiomyopathy, which is a relatively common Mendelian condition which puts affected individuals at risk of sudden cardiac death. My group’s work, using molecular biological, model organism and clinical research approaches, has led to the idea that energy compromise is a key disease mechanism; clinical trials are underway to test new medical therapies based on this finding. Our work on genetic causes of ‘sudden cardiac death’ syndromes has been translated into clinical practice through the Oxford BRC, leading to an NHS commissioned national DNA diagnostic service. This area of my work is integrally linked with the groups of Prof. Charles Redwood and Prof. Houman Ashrafian as we have worked closely together for many years.

I also lead a research group investigating susceptibility genes for coronary artery disease, now the main cause of premature mortality worldwide, working closely with Prof. Martin Farrall who leads on statistical genetic approaches. This work is now entering an exciting phase where we can use functional genomic tools to understand new biology. We have a particular interest in genetically implicated processes in the vessel wall and pursue this in collaboration with Prof. Keith Channon, Dr. Gillian Douglas and Prof. Ellie Tzima.

A current area of focus is exploring the basis of cardiac remodelling in hypertrophic cardiomyopathy, in particular the role of the immune system.

We have shown that there is metabolic crosstalk between stressed cardiomyocytes and neighbouring cells, and our preliminary data indicate that this, and other aspects of remodelling, are mediated, at least in part, by cells of the immune system that accumulate in HCM myocardium. We have shown that ablation of the adaptive immune system markedly worsens remodelling in a well-validated HCM mouse model. We hypothesise that local cardiac immune activity, both acquired and innate, plays an essential and dynamic role in HCM with, as is typical in immunity, a balance of deleterious and protective effects. We will test this by identifying the role of specific immune components in the progression of HCM using reductionist experiments in HCM mouse models, studies in affected human myocardium and large-scale human genetic interrogation. Identification of the immune activity involved will inform novel disease modifying therapy for established disease.

We also have active projects using human genetic approaches to define novel disease genes, and downstream mechanisms, in families with unexplained familial cardiac syndromes. This has been a productive source of insights into fundamental cardiac biology and also often leads to direct improvements in patient care.

Depending on the prior experience of the successful candidate, projects in the group would provide training in human genetic analysis, including gene discovery through whole genome sequencing, creation and analysis of mouse models and/or human iPSC-derived cardiomyocytes (both via genome-editing with CRISPR-cas9), cardiac phenotyping of mouse and cellular models. The immunology project will employ cutting edge approaches for investigating immune cell subsets, including single cell genomic analysis, well-established in vivo mouse models, advanced immunological and imaging techniques (e.g. FACSymphony, cell sorting, CyTOF, two-photon confocal fluorescence microscopy, and light sheet microscopy).

As well as the specific training detailed above, students will have access to high-quality training in scientific and generic skills, as well as access to a wide-range of seminars and training opportunities through the many research institutes and centres based in Oxford.

The Department has a successful mentoring scheme, open to graduate students, which provides an additional possible channel for personal and professional development outside the regular supervisory framework. We hold an Athena SWAN Silver Award in recognition of our efforts to build a happy and rewarding environment where all staff and students are supported to achieve their full potential.

Funding Notes

Our main deadline for applications for funded places has now passed. Supervisors may still be able to consider applications from students who have alternative means of funding (for example, charitable funding, clinical fellows or applicants with funding from a foreign government or equivalent). Prospective applicants are strongly advised to contact their prospective supervisor in advance of making an application.

Please note that any applications received after the main funding deadline will not be assessed until all applications that were received by the deadline have been processed. This may affect supervisor availability.
