CYP1B1 is polymorphic in cynomolgus and rhesus macaques

抄録

Cytochrome P450 (CYP) 1B1 is involved in the metabolic activation of various procarcinogens, and some CYP1B1 genetic variants alter CYP1B1-dependent procarcinogen metabolism. Cynomolgus and rhesus macaques are frequently used in toxicity tests due to their evolutionary closeness to humans. In this study, we attempted to identify CYP1B1 genetic variants in 13 cynomolgus and 4 rhesus macaques. A total of 17 genetic variants were identified, including 8 non-synonymous genetic variants, indicating that, similar to humans, CYP1B1 is polymorphic in macaques. These CYP1B1 genetic variants could be the basis for understanding potential inter-animal differences in macaque CYP1B1-dependent metabolism of promutagens.
