Functional and molecular characterization of UDP-glucuronosyltransferase 2 family in cynomolgus macaques.

UDP-glucuronosyltransferases (UGTs) are essential enzymes metabolizing endogenous and exogenous chemicals. However, characteristics of UGTs have not been fully investigated in molecular levels of cynomolgus macaques, one of non-human primates widely used in preclinical drug metabolism studies. In this study, three UGT2A cDNAs (UGT2A1, 2A2, and 2A3) were isolated and characterized along with seven UGT2Bs previously identified in cynomolgus macaques.

Molecular and functional characterization of UDP-glucuronosyltransferase 1A in cynomolgus macaques.

UDP-glucuronosyltransferases (UGTs) are drug-metabolizing enzymes essential for the metabolism of endogenous substrates and xenobiotics. Molecular characteristics of UGTs have been extensively investigated in humans, but in cynomolgus macaques, a non-human primate species widely used in drug metabolism studies, remain to be investigated. In this study, 12 UGT1A cDNAs (UGT1A1, 1A2, 1A4A, 1A4B, 1A5A, 1A5B, 1A5C, 1A6, 1A7, 1A8, 1A9, and 1A10) were isolated and characterized in cynomolgus macaques.
