1 Up-regulation of UDP-glucuronosyltransferase (UGT) 1A4 by 17beta-estradiol: a potential mechanism of increased lamotrigine elimination in pregnancy. Lamotrigine UDP glucuronosyltransferase family 1 member A4 Homo sapiens
2 In this study, we show that 17beta-estradiol (E(2)) up-regulates expression of UDP glucuronosyltransferase (UGT) 1A4, the major enzyme responsible for elimination of lamotrigine. Lamotrigine UDP glucuronosyltransferase family 1 member A4 Homo sapiens
3 Together, our data indicate that up-regulation of UGT1A4 expression by E(2) is mediated by both ER alpha and Sp1 and is a potential mechanism contributing to the enhanced elimination of lamotrigine in pregnancy. Lamotrigine UDP glucuronosyltransferase family 1 member A4 Homo sapiens
