The effect of clofibrate feeding on the NADP-linked dehydrogenases activity in rat tissue.
Administration of clofibrate to the rat increased several fold the activity of malic enzyme in the liver. Clofibrate treatment resulted also in an increased activity of the hepatic hexose monophosphate shunt dehydrogenases but was without effect on NADP-linked isocitrate dehydrogenase. The increased activity of malic enzyme in the liver resulting from the administration of clofibrate was inhibited by ethionine and puromycin, which suggests that de novo synthesis of the enzyme protein did occur as the result of the drug action. In contrast to the liver malic enzyme, the enzyme activity in kidney cortex increased only two-fold, whereas in the heart and skeletal muscle the activity was not affected by clofibrate administration.
