Research Interests

  • Mechanisms of exercise-induced cardioprotection
  • Protein O-GlcNAcylation in the heart
  • Cell signaling events in the heart in response to high fat diets and diabetes

Regular exercise provides protection against cardiovascular disease through a reduction of risk factors such as obesity, hypertension and blood lipids. Acute and short term exercise also provide protection against myocardial infarction (heart attack) by upregulation of protective proteins in heart muscle cells and this is independent of any change in risk factors.

My laboratory investigates the role of post-translational modification of proteins in exercise-induced cardioprotection, in addition to the cardiac response of the O-GlcNAc pathway to high fat diets and diabetes. Experimental techniques include in vivo mouse model (including forced and voluntary exercise training), cell culture, isolated heart perfusion, fluorescent microscopy, western blotting, and PCR.
