title: Induction by perfluorooctanoic acid of microsomal 1-acylglycerophosphocholine acyltransferase in rat kidney. Sex-related difference.
abstract: Response of rat kidney to the challenges by perfluorooctanoic acid (PFOA) was studied using microsomal 1-acyglycerophosphocholine (1-acyl-GPC) acyltransferase as a parameter. Marked induction of the enzyme was brought about in kidney of male rats, whereas the induction in kidney of female rats was far less pronounced. The sex-related difference in the response of kidney to PFOA was much more marked than those seen with p-chlorophenoxyisobutyric acid (clofibric acid) or 2,2'-(decamethy-lenedithio)diethanol (tiadenol). Hormonal manipulations revealed that the sex-related difference in the response of kidney to PFOA was strongly dependent on the state of gonadal hormones of rats. Even after a prolonged administration of PFOA for up to 26 weeks, this sex-related difference was still evident. Induction of peroxisomal beta-oxidation was brought about concurrently with microsomal 1-acyl-GPC acyltransferase and a high correlation was confirmed between the inductions of these two parameters.
