Dr. Garabedian’s lab is interested in understanding the Mechanism of Nuclear Hormone Receptor Action in Cancer, Heart Disease and Neuroendocrine Function:  Specific areas of research include 1) Regulation of neuronal function by the glucocorticoid receptor (GR) in stress adaptation, 2) Role of liver X receptor (LXR) alpha in cardiovascular disease, atherosclerosis and adipocyte function in diabetes,3) Rational design approaches for targeting the androgen receptor (AR) in therapy resistant prostate cancer.
