Cholesteryl ester transfer protein expressed in lecithin cholesterol acyltransferase-deficient mice.
OBJECTIVE Regulation of plasma cholesteryl ester transfer protein (CETP) concentration was studied in lecithin-cholesterol acyltransferase (LCAT)-knockout mice. METHODS AND RESULTS LCAT-knockout mice were cross-bred with CETP transgenic mice. The offspring (n=63) were classified for LCAT genotype and plasma CETP levels (no CETP, low CETP, and high CETP). High density lipoprotein (HDL) decreas...
Human (Hu) lecithin-cholesterol acyltransferase (LCAT) is a key enzyme in the plasma metabolism of cholesterol. To assess the effects of increased plasma levels of LCAT, four lines of transgenic mice were created expressing a Hu LCAT gene driven by either its natural or the mouse albumin enhancer promoter. Plasma LCAT activity increased from 1.2- to 1.6-fold higher than that found in control mo...
BACKGROUND Lecithin:cholesterol acyltransferase (LCAT) catalyzes the formation of plasma cholesteryl ester, plays a key role in high-density lipoprotein metabolism, and has been believed to be critical in the process of reverse cholesterol transport (RCT). METHODS AND RESULTS The role of LCAT in RCT from macrophages was quantified with a validated assay involving intraperitoneal injection in ...
Plasma lipoprotein metabolism is influenced by several factors that may act by regulating the expression of proteins involved in lipoprotein metabolism, such as lecithin:cholesterol acyltransferase (LCAT). We determined the influence of several hormones and hypolipidemic drugs on hepatic LCAT gene expression and plasma LCAT activity. Liver LCAT mRNA levels were resistant to regulation by the ho...
Lecithin:cholesterol acyltransferase (LCAT) catalyzes plasma cholesteryl ester formation and is defective in familial lecithin:cholesterol acyltransferase deficiency (FLD), an autosomal recessive disorder characterized by low high-density lipoprotein, anemia, and renal disease. This study aimed to investigate the mechanism by which compound A [3-(5-(ethylthio)-1,3,4-thiadiazol-2-ylthio)pyrazine...
We established five monoclonal antibodies that reacted with human LCAT and recognized different epitopes on LCAT. These are mouse anti-human LCAT monoclonal antibodies designated 36487, 36454, 36442, 36405, and 36486, which react with the peptides corresponding to human LCAT amino acid residues R159-E179, M258-S273, S274-S294, D352-S376, and N415-E440, respectively. We also successfully used tw...
Guiding and encouraging farmers to adopt low-carbon agricultural technologies is highly significant for reducing greenhouse gas emissions, mitigating climate change, achieving production development food security. This study used survey data from 1843 grain in 14 provinces of China empirically analyze the impact non-farm employment experience risk preferences on farmers’ technology (LCAT) adopt...
BACKGROUND Mutations in the LCAT gene cause lecithin:cholesterol acyltransferase (LCAT) deficiency, a very rare metabolic disorder with 2 hypoalphalipoproteinemia syndromes: classic familial LCAT deficiency (Online Mendelian Inheritance in Man No. 245900), characterized by complete lack of enzyme activity, and fish-eye disease (Online Mendelian Inheritance in Man No. 136120), with a partially d...
OBJECTIVE To better understand the role of lecithin:cholesterol acyltransferase (LCAT) in lipoprotein metabolism through the genetic and biochemical characterization of families carrying mutations in the LCAT gene. METHODS AND RESULTS Thirteen families carrying 17 different mutations in the LCAT gene were identified by Lipid Clinics and Departments of Nephrology throughout Italy. DNA analysis...
Lecithin:cholesterol acyltransferase (LCAT) is the enzyme responsible for cholesterol esterification in plasma. Mutations in the LCAT gene leads to two rare disorders, familial LCAT deficiency and fish-eye disease, both characterized by severe hypoalphalipoproteinemia associated with several lipoprotein abnormalities. No specific treatment is presently available for genetic LCAT deficiency. In ...
