SOURCE AND DESCRIPTION OF CLONE: A 1.65 kb ECORI cDNA insert corresponding to the full length hepatic lipase (HL) sequence isolated from a rat liver cDNA library (I). CHROMOSOMAL LOCALIZATION: Chromosome 15q21 by somatic cell and in situ hybridization (2).
Mice lacking hepatic lipase have been reported to express mild hyperlipidemia characterized by increased concentrations of large high density lipoproteins, but normal concentrations of lipoproteins containing apolipoprotein B. Whereas hepatic lipase has been implicated in the clearance and processing of chylomicron remnants in rats, no such defect was found in these mice. We have further charac...
Existing methods for determining the release of lipoprotein lipase (EC 3.1.1.34) and hepatic lipase (EC 3.1.1.3) into plasma after heparin injection give highly variable results, primarily traceable to errors in the isolation of labeled oleate from the substrate, triolein. Methods involving anion-exchange resin to bind oleate show high variability and have a low yield. Introducing a strong base...
Increases in plasma lipids occur during hypoxia in suckling but not in weaned rats and may result from altered hepatic enzyme activity. We exposed rats to 7 days of hypoxia from birth to 7 days of age (suckling) or from 28 to 35 days of age (weaned at day 21). Hypoxia led to an increase in hepatic lipid content in the suckling rat only. Hepatic lipase was decreased to approximately 45% of contr...
High hepatic lipase (HL) activity is associated with an atherogenic lipoprotein profile of small, dense LDL particles and lower HDL(2)-C. Intra-abdominal fat (IAF) is positively associated with HL activity. A hepatic lipase gene (LIPC) promoter variant (G-->A(-250)) is associated with lower HL activity, higher HDL(2)-C, and less dense LDL particles. To determine whether the LIPC promoter polymo...
Cholesterol ester storage disease (CESD) is a chronic liver disease that typically presents with hepatomegaly. It is characterized by hypercholesterolemia, hypertriglyceridemia, high-density lipoprotein deficiency, and abnormal lipid deposition within multiple organs. It is an autosomal recessive disease that is due to a deficiency in lysosomal acid lipase (LAL) activity, which is coded by the ...
Human hepatic lipase (hHL) is mainly localized on the hepatocyte cell surface where it hydrolyzes lipids from remnant lipoproteins and high density lipoproteins and promotes their hepatic selective uptake. Furthermore, hepatic lipase (HL) is closely associated with obesity in multiple studies. Therefore, HL may play a key role on lipid homeostasis in liver and white adipose tissue (WAT). In the...
using enrichment procedures, 45 organic solvent-tolerant lipase producer bacterial strains were screened from areas contaminated by oil and organic solvents. among the strains, 15 isolates exhibited extreme stability toward organic solvents and high lipolytic activity. the neb-1 isolate which was later identified as pseudomonas sp. strain neb-1 by biochemical tests and 16s rdna gene sequ...
OBJECTIVES We previously demonstrated coincident quantitative trait loci (QTLs) for percentage body fat, plasma hepatic lipase (HL) activity, and plasma cholesterol on mouse chromosome 7. In the present study, we investigated whether hepatic lipase (Lipc) is an obesity gene, whether Lipc interacts with an unknown gene on chromosome 7, and how HL activity is linked to the chromosome 7 locus. R...
The associations between six genetic polymorphisms in the hepatic lipase (HL) gene (LIPC) and variation in postheparin HL activity and fasting serum lipoproteins were evaluated in 395 male Finnish coronary heart disease patients with HDL cholesterol concentrations </= 1.1 mmol/liter. The LIPC promoter polymorphism at position -514 was highly significantly associated with variation in HL activit...
