Hepatic Lipase: a Comprehensive View of its Role on Plasma Lipid and Lipoprotein Metabolism.
نویسندگان
چکیده
Hepatic lipase (HL) is a key enzyme catalyzing the hydrolysis of triglycerides (TG) and phospholipids (PLs) in several lipoproteins. It is generally recognized that HL is involved in the remodeling of remnant, low-density lipoprotein (LDL), high-density lipoprotein (HDL) and the production of small, dense low-density lipoproteins (sd-LDLs).On the other hand, it is unclear whether HL accelerates or retards atherosclerosis. From the clinical point of view, HL deficiency may provide useful information on answering this question, but the rarity of this disease makes it impossible to conduct epidemiological study.In this review, we describe a comprehensive and updated view of the clinical significance of HL on lipid and lipoprotein metabolism.

Hepatic lipase, lipoprotein metabolism, and atherogenesis.
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...
متن کاملHepatic lipase expression in macrophages contributes to atherosclerosis in apoE-deficient and LCAT-transgenic mice.
Hepatic lipase (HL) has a well-established role in lipoprotein metabolism. However, its role in atherosclerosis is poorly understood. Here we demonstrate that HL deficiency raises the proatherogenic apoB-containing lipoprotein levels in plasma but reduces atherosclerosis in lecithin cholesterol acyltransferase (LCAT) transgenic (Tg) mice, similar to results previously observed with HL-deficient...
متن کاملLipid Metabolism and Thyroid Hormone : a Review
Thyroid hormone , secreted by thyroid gland have a profound effects on the lipid metabolism. It exerts its action mainly by its genomic action. It diffuses from the extracellular fluid across the plasma membrane and go directly into the nucleus. The cognate receptor binds to the thyroid hormone response element [TRE].It regulates the gene expression of key enzymes involved in lipid metabolism b...
متن کاملHepatic lipase: a pro- or anti-atherogenic protein?
Hepatic lipase (HL) plays a role in the metabolism of pro- and anti-atherogenic lipoproteins affecting their plasma level and composition. However, there is controversy regarding whether HL accelerates or retards atherosclerosis. Its effects on different lipoprotein classes show that, potentially, HL may promote as well as decrease atherogenesis. Studies in animals with genetically modulated HL...
متن کاملRegulation of plasma lipid homeostasis by hepatic lipoprotein lipase in adult mice[S]
LPL is a pivotal rate-limiting enzyme to catalyze the hydrolysis of TG in circulation, and plays a critical role in regulating lipid metabolism. However, little attention has been paid to LPL in the adult liver due to its relatively low expression. Here we show that endogenous hepatic LPL plays an important physiological role in plasma lipid homeostasis in adult mice. We generated a mouse model...
