Information regarding decabromodiphenyl ethane(DBDPE)effects on hepatotoxicity and metabolism is limited.In the present study,Wistar rats were given oral DBDPE at different doses.DBDPE induced oxidative stress,elevated blood glucose levels,increased CYP2B2 mRNA,CYP2B1/2protein,7-pentoxyresorufin O-depentylase(PROD)activity,and induced CYP3A2 mRNA,CYP3A2protein,and luciferin benzylether debenzylase(LBD)activity.UDPGT activity increased with its increasing exposure levels,suggesting that oral DBDPE exposure induces drug-metabolizing enzymes in rats via the CAR/PXR signaling pathway.The induction of CYPs and co-regulated enzymes of phase II biotransformation may affect the homeostasis of endogenous substrates,including thyroid hormones,which may,in turn,alter glucose metabolism.
