Research Interests

Protein O-GlcNAcylation and chromatin regulation; Cell signaling events in the heart in response to high fat diet, diabetes and/or exercise

Research Summary

My laboratory investigates post-translational O-GlcNAc protein modification in the heart in response to exercise, dietary manipulation and diabetes. Our current work is focused on the role of the O-GlcNAc pathway in modulation of cardiac chromatin regulation, gene transcription and downstream signaling pathways. Experimental techniques include in vivo mouse model (including forced and voluntary exercise training), cell culture, isolated heart perfusion, fluorescent microscopy, western blotting and PCR.
