Research Interest

Glucocorticoid regulation of eNOS expression in Caucasians and African Americans. Studies on racial differences in endothelial biology, particularly in response to glucocorticoids, estrogen, progesterone, and growth factors (insulin, fibroblast growth factor, and vascular endothelial growth factor).

New projects include: 1) the discovery of the Brown Norway rat as a model of placental insufficiency leading to fetal loss. This animal model presents renin-angiotensin system activation which is linked to a particular ACE polymorphism. In addition, Brown Norway rats present decreased vitamin D activation. 2) Studies on the effects of tumor necrosis alpha (TNF) and its mechanisms of inflammation in human endothelial cells. Study of polymorphisms in the TNF receptors to explain variability in response to TNF.
