The aim of this study was to evaluate the mRNA expression of CYP1-CYP3 families in cats exposed to BDE-209 for one year. All selected CYP isoforms showed no significant difference in mRNA expressions between control and exposure groups, however, CYP3A12 and CYP3A131 revealed tend to be two times higher in the exposure group compared to control group. The present results indicate that the chronic exposure of BDE209 could not alter CYP expression in the liver of cats. This result considered caused by the deficiency of CYP2B subfamily which is major metabolism enzyme of polybrominated diphenyl ethers ( PBDEs) in cat.公益社団法人 日本獣医学会 (The Japanese Society of Veterinary Science)Journal Articlehttp://hdl.handle.net/2115/801420916-7250Journal of veterinary medical science8279789822020-07-31enginfo:doi/10.1292/jvms.20-0140none
