1. A selective immunochemical method was used to measure post-heparin plasma lipoprotein lipase and hepatic lipase activity in eighty-two normal subjects and in twenty patients with type IIb, IV or V hypertriglyceridaemia. In twenty-six normal subjects the activity of post-heparin plasma lipases was compared with the kinetic parameters of endogenous plasma triglyceride metabolism. 2. The activi...
The role of hepatic lipase as a multifunctional protein that modulates lipoprotein metabolism and atherosclerosis has been extensively documented over the last decade. Hepatic lipase functions as a lipolytic enzyme that hydrolyzes triglycerides and phospholipids present in circulating plasma lipoproteins. Hepatic lipase also serves as a ligand that facilitates lipoprotein uptake by cell surface...
Triacylglycerol lipase activities of homogenates and subcellular fractions of rat liver were measured under optimal conditions at pH 7.5 using emulsified tri[1-14C]oleoylglycerol as substrate. Twenty-four hr after administration of streptozotocin, hepatic alkaline lipase activity was 39% of normal, and this lower level of activity was observed at 72 hr and 7 days, after streptozotocin injection...
Rat hepatic lipase is a glycoprotein bearing two N-linked oligosaccharide chains. The importance of glycosylation in the secretion of hepatic lipase was studied using freshly isolated rat hepatocytes. Various inhibitors of oligosaccharide synthesis and processing were used at concentrations that selectively interfere with protein glycosylation. Secretion of hepatic lipase activity was abolished...
the present study was undertaken to screen the soil samples collected in iran for the presence of the bacillus subtilis lipase a gene. the bacterial colonies obtained from the collected soil samples were examined by physical appearance, biochemical tests and the polymerase chain reaction (pcr). only four colonies were identified as putative b. subtilis strains and all contained the lipase a ge...
To test whether lipoprotein lipase or hepatic lipase activities are associated with lipoprotein subclasses, and to assess the effects of dietary manipulations on these associations, enzyme activities were measured in postheparin plasma (75 U heparin/kg) from 43 healthy men who were randomly allocated to a low-fat (24% fat, 60% carbohydrate) and a high-fat (46% fat, 38% carbohydrate) diet for 6 ...
We studied the interstitial fluid concentration of two lipid-metabolizing enzymes (lipoprotein lipase and hepatic triacylglycerol lipase) to determine their importance in interstitial modification of filtered lipoproteins. Despite the use of a very sensitive lipase assay (1 nmol of fatty acid release/ml/hr), lipase activities in plasma and in peripheral and skeletal muscle lymph from control do...
We compared two methods for the direct selective measurement of hepatic lipase and lipoprotein lipase activities in human plasma after intravenous administration of heparin. Except for the emulsifier (gum arabic vs lecithin), the two assay media for hepatic lipase are essentially similar. Results for hepatic lipase by these two assays correlate well (r = 0.99). The assays for lipoprotein lipase...
