| Research Abstract |
UDP-glucuronosyltransferase 1A1(UGT1A1) is the only physiological relevant enzyme in bilirubin glucuronidation. Mutations of the UGT1A1 gene reduce the enzyme activity, leading unconjugated hyperbilirubinemia. Bilirubin has two sites capable of glucuronidation and forms bilirubin mono-and di-glucuronides(BMG and BDG). We constructed the several expression plasmids for UGT1A1 with missense mutation(G71R, F83L, I322V, and G493R) in the gene. In this study, we established the high-throughput quantitative methods for BMG and BDG using UPLC-Orbitrap MS technique, and estimated each glucuronidation capacity of the mutated UGT1A1 by transient transfection and expression.
