Lecithin:cholesterol acyltransferase: symposium on 50 years of biomedical research from its discovery to latest findings J Lipid Res. Aug;61(8) doi: /jlr.S. COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated.
Purpose of review: We discuss the latest findings on the biochemistry of lecithin: cholesterol acyltransferase (LCAT), the effect of LCAT on atherosclerosis, clinical features of LCAT deficiency, and the impact of LCAT on cardiovascular disease from human studies.
Recent findings: Although there has been much recent Cited by: To review recent lecithin:cholesterol acyltransferas (LCAT)-based therapeutic approaches for atherosclerosis, acute coronary syndrome, and LCAT deficiency disorders. Lecithin cholesterol acyltransferase (LCAT) (EC), a lipoprotein-associated enzyme, is a key player in the reverse cholesterol transport (RCT) pathway, which promotes the transfer of excess cellular cholesterol Cited by: Cholesterol transport in circulation and its removal from tissues depends on the activity of lecithin cholesterol acyltransferase (LCAT).
LCAT is a soluble enzyme that converts cholesterol and. Abstract Low high-density lipoprotein-cholesterol (HDL-c) is the most remarkable lipid trait both in mild-to-moderate chronic kidney disease (CKD) patients as well as in advanced renal disease stages, and we have previously shown that reduced lecithin:cholesterol acyltransferase (LCAT.
Lecithin cholesterol acyltransferase (LCAT) is reported to be closely involved in reverse cholesterol transport (RCT), which is an anti-atherogenic process by which excess cholesterol.

33, No. ABSTRACT. The phospholipase A 2 and acyltransferase activities characteristic of human plasma lecithin: cholesterol acyltransferase have been evaluated in incubation mixtures of lipoprotein. A French pharmacist discovered lecithin in the mid th century. It is a key component of egg yolks.
Although it is often said to lower cholesterol, the European Food Safety Authority concluded in that there was inadequate proof to recommend lecithin. The polypeptide molecular weight of lecithin–cholesterol acyltransferase (LCAT) (45 ) was obtained by deducting the weight of carbohydrate moiety (25%, w/w) from the total molecular weight.
Lecithin:cholesterol acyltransferase (LCAT) is a key plasma enzyme in cholesterol and high density lipoprotein (HDL) metabolism. Transgenic rabbits overexpressing human LCAT had fold greater plasma LCAT activity that nontransgenic control rabbits.
This degree of overexpression was associated with a fold increase in the plasma HDL cholesterol. Lecithin cholesterol acyltransferase (LCAT) is a glycoprotein that has both a phospholipase A2 and an acyltransferase action. It is essential for the normal maturation, interconversion and rearrangements of all lipoprotein classes and is involved in reverse cholesterol transport.
Enhancement of LCAT (lecithin:cholesterol acyltransferase) activity has possibility to be beneficial for atherosclerosis. To evaluate this concept, we characterized our novel, orally administered, small-molecule LCAT activator DSa. Lecithin: cholesterol acyltransferase (LCAT)(EC ) is generally assumed to participate in reverse cholesterol transport, i.e., cholesterol transport from peripheral tissues to the liver.
The Lecithin Cholesterol Acyltransferase (LCAT) Reaction animation, featured on Chapter of OMMBID. Glycogen Degradation Animation The Glycogen Degradation animation. Lecithin:cholesterol acyltransferase (LCAT) is a key enzyme in the metabolism of high-density lipoprotein (HDL).
It is responsible for the synthesis of cholesteryl esters (CEs) in human plasma by catalyzing a reaction in which a fatty acyl residue from the sn-2 position of phosphatidylcholine is transferred to the 3-beta-hydroxy group of cholesterol.
We identified a novel missense mutation in the lecithin:cholesterol acyltransferase gene in a new case of lecithin:cholesterol acyltransferase (LCAT) deficiency. The patient was a year-old diabetic Japanese male who showed an extremely low level of serum high-density lipoprotein-cholesterol.
Plant phospholipase A has long been proposed to contribute to hydroxy fatty acid (HFA) enrichment, but the specifics of this process remain elusive. The current study showed that Physaria fendleri an. Although the major function of lecithin-cholesterol acyltransferase (LCAT) is cholesterol esterification, our previous studies showed that it can also hydrolyze platelet-activating factor (PAF).
a new serine esterase inhibitor, which had no effect on LCAT at this concentration. On the other hand, 1 m m ↵ * This research. Abstract. Lecithin–cholesterol acyltransferase (LCAT) is the major enzyme responsible for the esterification of free cholesterol on plasma lipoproteins, which is a key step in the reverse cholesterol.
Lecithin: cholesterol acyltransferase--from biochemistry to role in cardiovascular disease. Curr Opin Endocrinol Diabetes Obes. Recent research findings from animal and human studies have.
Human plasma contains lecithin:cholesterol acyltransferase (LCAT; EC ), which is the key enzyme responsible for esterification of free cholesterol to cholesteryl esters ().Small-sized, lipid-poor.
Lecithin:cholesterol acyltransferase (LCAT) has been purified from human plasma by sequential preparative ultracentrifugation, ion-exchange chromatography on DEAE-Sephacel, and affinity.
They had an almost complete lack of esterified cholesterol in plasma, and a high concentration of plasmafree cholesterol. The plasma concentrations of lecithin were high and of lysolecithin low.
These abnormalities were found to be associated with an absence of plasma lecithin: cholesterol acyltransferase. Sterol O-acyltransferase (also called Acyl-CoA cholesterol acyltransferase, Acyl-CoA cholesterin acyltransferase  or simply ACAT) is an intracellular protein located in the endoplasmic reticulum that forms cholesteryl esters from cholesterol.
Sterol O-acyltransferase catalyzes the chemical reaction. acyl-CoA + cholesterol ⇌ CoA + cholesterol. ent allelic mutations in the lecithin:cholesterol acyltransferase by guest, on June 2, Downloaded from Brousseau et al. Cor rection of hypoalphalipoproteinemia in LDLr deﬁciency. Lecithin cholesterol acyl transferase (LCAT) deficiency is associated with low high-density lipoprotein (HDL) and the presence of an abnormal lipoprotein called lipoprotein X (Lp-X) that contributes to end.
Book Description. Advances in Cholesterol Research presents a range of topics which, for the most part, have not been reviewed in recent years in books published on cholesterol.
The subject area can be divided into two main sections. The intracellular and extracellular dynamics of cholesterol. Familial LCAT deficiency is a genetic disorder caused by mutations in the LCAT gene.
The LCAT gene provides instructions for making an enzyme (protein) called lecithin-cholesterol acyltransferase (LCAT). This enzyme is involved in removing cholesterol.
A disorder of lipoprotein metabolism characterized by inadequate esterification of plasmatic cholesterol. Two clinical forms are recognized: complete LCAT deficiency and fish-eye disease.

High-density lipoprotein (HDL) is well-known for its cardioprotective effects, as it possesses anti-inflammatory, anti-oxidative, anti-thrombotic, and cytoprotective properties. Traditionally, studies and therapeutic approaches have focused on raising HDL cholesterol levels.
