  • Title: [Effect of clofibrate on intracellular enzyme distribution in the rat liver].
    Author: Panchenko LF, Popova SV, Pirozhkov SV, Antonenkov VD.
    Journal: Tsitologiia; 1983 Nov; 25(11):1302-8. PubMed ID: 6659071.
    Abstract:
    The effect of chronic administration of a hypolipaemic agent--clofibrate--on the subcellular distribution of liver enzymes in male rats was studied. Clofibrate produced an increase in the number of peroxisomes and also enhanced the activity of aconitase and histidine: glyoxylate aminotransferase (HGA) in liver homogenate. Differential centrifugation of homogenate revealed an elevation of the relative amounts of catalase, HGA and isocitrate dehydrogenase in the soluble cell fraction in clofibrate pretreated animals. Clofibrate induced peroxisomal HGA but failed to alter the amounts of catalase, urate oxidase and isocitrate dehydrogenase in the particles. In both the experimental and control groups the activity of aconitase, malate dehydrogenase (NAD+), creatine phosphokinase and glutathione reductase was observed in mitochondrial fractions and was not detected in purified peroxisomes.
