Defining the function of new causal atherosclerosis genes from CAD GWAS loci using in vitro and in vivo models


About the research

Despite significant advancements in its treatment coronary artery disease is the leading cause of death in both the UK and world wide, accounting for over 66,000 deaths in the UK each year. Genome wide association studies have enabled us to identify genes which are associated with cardiovascular disease at the level of the whole genome. These novel genes, which are not associated with traditional risk factors, have the potential to identify novel treatment strategies for coronary artery disease. However, the challenge now is to establish the role of these genes in the pathology of cardiovascular disease. The work in my lab aims to establish the role of novel candidate genes in cardiovascular disease.

Working in close collaboration with bioinformaticians we   identify novel candidate genes from GWAS implicated loci. Once suitable   candidate genes have been identified, we use In vitro cell based assays    in primary human cells to established how the loss of the candidate   gene alters basic cell functions such proliferation, migration, respiration   and the response to physical stimuli such as flow, using state of the art   cellular imaging equipment as well as basic molecular biology skills. The   information gained from these In vitro   studies is then used in a targeted fashion to investigate the role of the   candidate gene in models of In vivo   cardiovascular disease, in particular the development and regression of   atherosclerosis and models of altered vascular function such as vascular   injury and ischaemia models.

Doctorial students have the flexibility to focus either on   in vitro cell based assays or in vivo models of cardiovascular   disease. A typically In vitro project would involve investigating the   expression profile gene of interest in tissue (e.g. arteries with or without   atherosclerosis and cells (e.g endothelial cells, vascular smooth muscle   cells and inflammatory cells)    implicated in coronary artery disease. This would be followed by   assessment of the consequences of loss or gain or function of the gene on   cell function.  It is not anticipated   that within the time of the project that detailed in vivo analysis of the   gene of interest would be achievable. However, if the student was interested   there maybe the scope to extend this project to in vivo studies. In a   typically in vivo project, the   student will assess the how loss or gain of function of the candidate gene   alters vascular function. We will evaluate physiological parameters such as   blood pressure and contractile and dilator function of blood vessels before   going on to investigate the role of the candidate gene in vascular pathology   using models of atherosclerosis and vascular injury.

Training Opportunities

This DPhil will be based in the Division of Cardiovascular Medicine at the Welcome Centre for Human Genetics. We are part of a wider scientific community with expertise in Cardiovascular Disease allowing for collaborative work with other senior scientist. By the end of this project the candidate will have developed a wide range of laboratory skills such as molecular biology techniques (protein and RNA analysis), cell culture techniques and In vivo models of cardiovascular disease. Training in scientific techniques as well as scientific presentation and writing will be given throughout the project.

Students are encouraged to attend the MRC Weatherall Institute of Molecular Medicine DPhil Course, which takes place in the autumn of their first year. Running over several days, this course helps students to develop basic research and presentation skills, as well as introducing them to a wide-range of scientific techniques and principles, ensuring that students have the opportunity to build a broad-based understanding of differing research methodologies.

Generic skills training is offered through the Medical Sciences Division's Skills Training Programme. This programme offers a comprehensive range of courses covering many important areas of researcher development: knowledge and intellectual abilities, personal effectiveness, research governance and organisation, and engagement, influence and impact. Students are actively encouraged to take advantage of the training opportunities available to them.

As well as the specific training detailed above, students will have 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.
