Low Density Lipoproteins Produced in Vitro by Lipoprotein Lipase Action on Nonsuppressive Very Low Density Lipoprdteins*
Very low density lipoproteins (VLDL), Sf60 to 400, from normolipemic individuals do not suppress 3-hydroxy-3-methylglutaryl-CoA reductase activity in cultured normal human fibroblasts at concentrations 20fold higher than those of low density lipoproteins (LDL) that give total suppression. To determine if these VLDL contain all of the structural elements necessary for receptor-mediated suppressi...
متن کاملEnhanced lipoprotein lipase secretion from human monocyte-derived macrophages caused by hypertriglyceridemic very low density lipoproteins.
We studied the effects of very low density lipoprotein (VDL) obtained from hypertriglyceridemic subjects on the secretion of lipoprotein lipase and lipid accumulation in human monocyte-derived macrophages. The incubation of macrophages with VLDL obtained from different subjects caused different effects on the secretion of lipoprotein lipase (6.8 to 137.7 nM free fatty acid/min/mg cell protein) ...
متن کاملVery low density lipoproteins and lipoprotein lipase in serum of rats deficient in essential fatty acids.
Rats fed a diet deficient in essential fatty acids have a low level of serum very low density lipoproteins (VLDL). It was found that after intraperitoneal injection of heparin, deficient rats had a higher level of lipoprotein lipase activity in their plasma than did normal rats. VLDL isolated from serum of normal and deficient rats were compared as substrates for postheparin lipase of rat plasm...

1. Human total HDL (high-density lipoprotein), HDL2 and HDL3 were labelled in vitro by incubation with lipoproteindeficient serum (LPDS) which contained either [3H]cholesteryl oleate or [14C]cholesterol under different conditions. The lipoproteins were then subfractionated by heparin-Sepharose column chromatography, and three subfractions (A, B and C) were successively eluted from each preparat...
متن کاملLipoprotein Lipase Increases Low Density Lipoprotein Retention
Lipoprotein lipase (LPL), the rate-limiting enzyme for hydrolysis of plasma lipoprotein triglycerides, is a normal constituent of the arterial wall. We explored whether LPL affects (a) lipoprotein transport across bovine aortic endothelial cells or (b) lipoprotein binding to subendothelial cell matrix (retention). When bovine milk LPL was added to endothelial cell monolayers before addition of ...
