Abstract

The dioxin receptor is a ligand-activated transcription factor with multiple functions in xenobiotic metabolism, development and dioxin toxicity. The focus here is on its roles in regulating endo- and xenobiotic conjugation by UDP-glucuronosyltransferases, and in dioxin-mediated cancer progression. Dioxins are poorly metabolized leading to sustained receptor activation and deregulation of target genes.
