The UDP-glucuronosyltransferase (UGT) enzymes are endoplasmic reticulum membrane bound proteins that catalyze the transfer of glucuronyl group from uridine 5’-diphosphogulucoronic acid to insoluble molecules (endogenous/exogenous) including steroids there by facilitating their excretion. These enzymes are highly expressed in liver, which is the major site for detoxification, and extrahepatic tissues where endogenous steroids need to be glucuronidated. Deregulation of UGT2B genes expression has been proposed as one of the contributors of abnormal cell proliferation in cancer cells. UGT2B28, 17, and 15 are expressed in prostate cancer cells. In our lab, I study 1) the effect of EGF on regulation of these genes in androgen dependent (LNCaP) and androgen independent (PC-3) cells 2) unraveling the EGF signaling pathway(s) that lead to these effects.
