Relation of plasma high-density lipoprotein cholesterol to lipoprotein-lipase activity in adipose tissue and skeletal muscle of man. 1978

E A Nikkilä, and M R Taskinen, and M Kekki

Lipoprotein-lipase activity (LPL) was measured in biopsies of adipose tissue and skeletal muscle of normal human subjects, and the results were related to concentrations of cholesterol and triglycerides in plasma lipoproteins. Adipose-tissue LPL activity was significantly higher in females than in males, whereas no sex difference was observed in skeletal-muscle LPL activity. A highly significant positive correlation was present between the plasma high density lipoprotein (HDL) cholesterol level and LPL activity in adipose tissue (r = +0.66, P less than 0.001) but not between HDL and skeletal-muscle LPL. The results suggest that the activity of LPL in adipose tissue and the rate of catabolism of triglyceride-rich lipoproteins might be one of the factors that determine the concentration of HDL in plasma and at least partly account for the known sex difference in plasma HDL level.

UI MeSH Term Description Entries
D008071 Lipoprotein Lipase An enzyme of the hydrolase class that catalyzes the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. The enzyme hydrolyzes triacylglycerols in chylomicrons, very-low-density lipoproteins, low-density lipoproteins, and diacylglycerols. It occurs on capillary endothelial surfaces, especially in mammary, muscle, and adipose tissue. Genetic deficiency of the enzyme causes familial hyperlipoproteinemia Type I.

D008075 Lipoproteins, HDL A class of lipoproteins of small size (4-13 nm) and dense (greater than 1.063 g/ml) particles. HDL lipoproteins, synthesized in the liver without a lipid core, accumulate cholesterol esters from peripheral tissues and transport them to the liver for re-utilization or elimination from the body (the reverse cholesterol transport). Their major protein component is APOLIPOPROTEIN A-I. HDL also shuttle APOLIPOPROTEINS C and APOLIPOPROTEINS E to and from triglyceride-rich lipoproteins during their catabolism. HDL plasma level has been inversely correlated with the risk of cardiovascular diseases.
