  • Title: Effect of p-chlorophenoxyisobutyrate (CPIB) fed to rats on hepatic biosynthesis and catabolism of ubiquinone.
    Author: Lakshmanan MR, Phillips WE, Brien RL.
    Journal: J Lipid Res; 1968 May; 9(3):353-6. PubMed ID: 5650929.
    Abstract:
    The effect of p-chlorophenoxyisobutyrate (CPIB) feeding on cholesterol and ubiquinone metabolism in rats was investigated. The results obtained from acetate-1-(14)C and mevalonate-2-(14)C incorporation studies both in vivo and in vitro confirm the results of other workers that CPIB feeding caused a metabolic block in the conversion of acetate to mevalonate, thereby inhibiting over-all steroidogenesis. Liver ubiquinone synthesis was inhibited in CPIB-fed rats, but a block in the catabolism of the ubiquinone resulted in accumulation of ubiquinone in CPIB-fed animals.
