Tyrosine kinase inhibitors (TKIs) are anticancer drugs that may be co-administered with other drugs. The aims of this study are to investigate the inhibitory effects of TKIs on UDP-glucuronosyltransferase (UGT) activities, and to quantitatively evaluate their potential to cause drug-drug interactions (DDIs). Inhibition kinetic profiles of a panel of UGT enzymes (UGT1A1, 1A3, 1A4, 1A6, 1A7, 1A8,...
Canagliflozin (CNF) and dapagliflozin (DPF) are the first sodiumglucose cotransporter 2 inhibitors to be approved for clinical use. Although available evidence excludes clinically significant inhibition of cytochromes P450, the effects of CNF and DPF on human UDP-glucuronosyltransferase (UGT) enzymes are unknown. Here, we report the inhibition of human recombinant UGTs by CNF and DPF, along wit...
Variation in serum bilirubin is associated with altered cardiovascular disease risk and drug metabolism. We aimed to identify genetic contributors to variability in serum bilirubin levels by combining results from three genome-wide association studies (Framingham heart study, n = 3424; Rotterdam study, n = 3847; Age, Gene, Environment and Susceptibility-Reykjavik, n = 2193). Meta-analysis showe...

The UDP-glucuronosyltransferases (UGTs) have long been known to be inducible by various chemicals, including drugs, although the extent of induction in general has been modest. In the present study, we determined the ability of the dietary flavonoid chrysin to induce UGT activity, protein and mRNA. When pretreating human hepatoma Hep G2 cells with 25 microM chrysin, the glucuronidation of chrys...

To clarify the UDP-glucuronosyltransferase (UGT) isoform(s) responsible for the glucuronidation of the thyroid hormone thyroxine (T(4)) in the human liver, the T(4) glucuronidation activities of recombinant human UGT isoforms and microsomes from seven individual human livers were comparatively examined. Among the 12 recombinant human UGT1A and UGT2B subfamily enzymes examined, UGT1A1, UGT1A3, U...
High-dose FOLFIRI has an acceptable safety profile and promising efficacy. UDP-glucuronosyltransferase: (UGT1A1) polymorphism may be predictive of toxicity and efficacy of irinotecan. This phase II study aimed to evaluate the combination of high-dose FOLFIRI plus bevacizumab in patients with previously untreated metastatic colorectal cancer (MCRC) based on their UGT1A1 genotype. Patients with t...
conclusions the present findings showed that the ta7/7 promoter of ugt1a1 gene accounted for a considerable number of gilbert’s syndrome cases (11.3%). the studied variations had a significant effect on creatine phosphokinase and serum total bilirubin levels. results about 78.9% of the studied subjects had normal homozygous genotypes, and 21.1% were heterozygous for the gly71arg variation. in t...
Troglitazone glucuronidation in human liver and intestine microsomes and recombinant UDP-glucuronosyltransferases (UGTs) were thoroughly characterized. All recombinant UGT isoforms in baculovirus-infected insect cells (UGT1A1, UGT1A3, UGT1A4, UGT1A6, UGT1A7, UGT1A8, UGT1A9, UGT1A10, UGT2B7, and UGT2B15) exhibited troglitazone glucuronosyltransferase activity. Especially UGT1A8 and UGT1A10, whic...
