Control of steroid, heme, and carcinogen metabolism by nuclear pregnane X receptor and constitutive androstane receptor
18 Mar 2003
Abstract excerpt
Through a multiplex promoter spanning 218 kb, the phase II UDP-glucuronosyltransferase 1A (UGT1) gene encodes at least eight differently regulated mRNAs whose protein products function as the principal means to eliminate a vast array of steroids, heme metabolites, environmental toxins, and drugs. The orphan nuclear receptors pregnane X receptor (PXR) and constitutive androstane receptor (CAR) were originally...
