Major Areas of Research Interest: 

My laboratory investigates mechanisms contributing to insulin resistance that occur as a result of physical inactivity, obesity, and the cardiometabolic syndrome. We are particularly interested in defining the contribution of the renin-angiotensin-aldosterone system (RAAS), reactive oxygen species (ROS) and inflammation in preventing normal skeletal muscle insulin signaling. Skeletal muscle cell and tissue cultures, and whole animal responses to insulin by euglycemic-hyperinsulinemic clamp are used to study cellular insulin signaling pathways and tissue responses to insulin. I am also studying the effects of insulin resistance on mitochondrial.

Research Activities: 

1) Determining the effect of angiotensin II on skeletal muscle NAD(P)H oxidase activity and reactive oxygen species using Ren-2 transgenic and Zucker obese rat models, and myoblast/myotube cell cultures.

2) Determining the effects of angiotensin II receptor or mineralcorticoid receptor blockade on skeletal muscle insulin signaling and glucose transport.

3) Determining the effects of physical inactivity, mitochondrial dysfunction, and ectopic lipid accumulation on NAD(P)H oxidase activity, oxidative stress and tissue resistance to insulin.

4) Determining the role of inflammatory cytokines on the development of tissue insulin resistance in skeletal muscle cell cultures, and hypertensive and obese animal models.

5) Determining the mechanisms by which insulin up-regulates skeletal muscle mitochondrial oxidative capacity.
