title: Selective increase in acylation of 1-acylglycerophosphorylcholine in livers of rats and mice by peroxisome proliferators.
abstract: Rats were fed a diet containing p-chlorophenoxyisobutyric acid (clofibric acid). Activity of microsomal 1-acylglycerophosphorylcholine (1-acyl-GPC) acyltransferase in liver was increased approx. 3-fold by the treatment with clofibric acid. The treatment of rats with clofibric acid did not increase activity of microsomal 2-acyl-GPC acyltransferase. Feeding a diet containing 2,2'-(decamethylenedithio)diethanol (tiadenol), di(2-ethylhexyl)phthalate or acetylsalicylic acid also resulted in a selective increase in the activity of 1-acyl-GPC acyltransferase in rat liver. Treatment with clofibric acid increased the activity of 1-acyl-GPC acyltransferase in liver of mouse as well as rat, but did not change the activity in liver of guinea-pig. The relative rate of acylation of 1-acyl-GPC with various acyl-CoAs by hepatic microsomes was not changed by the treatment of rats with clofibric acid.
