  • Title: Effect of pantethine on post-heparin plasma lipolytic activities and adipose tissue lipoprotein lipase in rats.
    Author: Noma A, Kita M, Okamiya T.
    Journal: Horm Metab Res; 1984 May; 16(5):233-6. PubMed ID: 6735346.
    Abstract:
    The lipid-lowering effect of pantethine, a new drug affecting lipid metabolism, had been evaluated in carbohydrate-induced hyperlipidemic rats. Administration of the drug raised post-heparin lipolytic activities, the change being due to an increase in lipoprotein lipase activity, whereas hepatic lipase activity remained virtually unchanged. Total lipoprotein lipase activity per g of adipose tissue increased in pantethine-treated rats compared with controls. Furthermore, the soluble lipoprotein lipase of fat-pads was fractionated by heparin-Sepharose affinity chromatography. The first active peak, originated from the microsomal fractions, significantly increased after the drug treatment, while the second one, originated from the plasma membranes, remained unchanged. The increase in the microsomal lipoprotein lipase activity may be due to an increase in intracellular synthesis of lipoprotein lipase enzyme proteins. The heterogeneity of lipoprotein lipase of rat adipose tissues was ensured using affinity chromatography on heparin-Sepharose.
