The Pregnane X Receptor: A Promiscuous Xenobiotic Receptor That Has Diverged during Evolution
1 Jan 2000
Abstract excerpt
Transcription of genes encoding cytochrome P450 3A (CYP3A) monooxygenases is induced by a variety of xenobiotics and natural steroids. There are marked differences in the compounds that induce CYP3A gene expression between species. Recently, the mouse and human pregnane X receptor (PXR) were shown to be activated by compounds that induce CYP3A expression. However, most studies of CYP3A regulation have been...
