Inducing effects of clofibric acid on 1-acylglycerophosphorylcholine acyltransferase in kidney and intestinal mocusa of rats
1986
Abstract Administration of p -chlorophenoxyisobutyric acid (clofibric acid) markedly increased the activity of microsomal 1-acylglycerophosphorylcholine (1-acyl-GPC) acyltransferase in kidney, intestinal mucosa and liver, but not in brain, heart, lung, spleen, testis or skeletal muscle. In both kidney and liver, a marked dose-dependent increase in the activities of both microsomal 1-acyl-GPC acyltransferase and peroxisomal β-oxidation was observed. In the rats treated with clofibric acid at a relatively low dose, the increase in the activity of 1-acyl-GPC acyltransferase in kidney was more marked than that in liver. The extent of the relative increase in the activity of 1-acyl-GPC acyltransferase to the activity of peroxisomal β-oxidation in kidney was more marked than that in liver. The increased activity of 1-acyl-GPC acyltransferase in both kidney and liver lasted throughout the 8-week treatment period of rat with clofibric acid.
