Faculty Research Interests

Gail Adler, M.D., Ph.D.

Dr. Adler is studying the role of the mineralocorticoid receptor (MR) in cardiovascular pathology. Recent data from her laboratory and others document that MR activation is associated with cardiac hypertrophy, fibrosis, nephropathy and strokes in experimental animals.  Her research is directed at elucidating the molecular and cellular mechanisms underlying these effects using several animal models: 1) nitric oxide synthase inhibition with ANGlI and dietary Na⁺ supplementation; 2) uni-nephrectomy with aldosterone and dietary Na⁺ supplementation; 3) streptozotocin treatment (a model of type 1 diabetes mellitus); 4) the db/db mouse (a model of type 2 diabetes mellitus); 5) several genetically manipulated mouse models.  Experiments are being conducted to define the role of modulators and/or intermediaries of MR-induced cardiovascular damage, including estradiol, ANGlI, PAl-l, and the receptor for advanced glycosylation end products. Finally, these laboratory based studies provide a scientific foundation for studies being conducted in patients  to determine the effects of MR antagonists on renovascular and cardiovascular function in diabetes.
