Diabetic cardiomyopathy – an epidemic disease

Globally, diabetes is an epidemic disease with a specific cardiopathology independent of associated cardiovascular risk profiles. Diabetic hearts are more vulnerable to developing failure, especially after a myocardial infarct. Our work focuses on understanding the metabolic and structural changes leading to both diastolic and systolic dysfunction, examining how circulating glucose and insulin impacts on cardiopathology and identifying potential molecular targets for intervention. This project will utilise experimental models of type 1 and type 2 diabetes to investigate the molecular and structural adaptations in the diabetic heart . We use cutting edge gene delivery and gene editing tools to create boutique experimental models of disease. This project may also involve work with clinical biopsy samples, as part of an associated project to develop biomarkers for early detection of cardiomyopathic disease.
This research project is available to PhD students, Masters by Research, Master of Biomedical Science to join as part of their thesis.
