Introduction: The UGT-Glucuronosyltransferase (UGT) 1A7 plays an important role in the metabolism of endogenous and xenobiotic substrates, which include environmental carcinogens and drugs such as the chemotherapeutic compound irinotecan. Low activity alleles of UGT1A7 characterized by variations within the coding and non-coding sequence are associated with cancer predisposition and drug toxicity. The transcriptional regulation of this gene by xenobiotics and a putative influence of SNP variants not completely characterized. Aim of this study was therefore to analyze the regulation of UGT1A7 via TCDD and to eluc…
