Fatty liver is independently associated with alterations in circulating HDL2 and HDL3 subfractions.
F atty liver is associated with insulin resistance, atherosclerosis, and the metabolic syndrome (1–7) and predicts future cardiovascular events (4–8). The pro-atherogenic serum lipid profile in subjects with fatty liver is characterized by elevated levels of triglycerides, low HDL cholesterol, and an increase in small dense LDL particles (9–12). Regarding HDL, not only quantitative, but also qu...
full textisolation of hdl2 and hdl3 assessment of concentration of cholesterol
the major lipoprotein classes are heterogenous. human serum high-density-lipoproteins (hdl) are separated into two major subfractions (hdl2, d=1.063-1.125 g/ml, hdl3, d=1.125-1.210 g/ml) by a simple double precipitation method. there was a strong inverse relation between hdl-cholesterol (hdl-c) and subfractions hdl2-c and hdl3-c with atherosclerosis. this study demonstrated that hdl-c (p<0.001)...
full textBeyond HDL-cholesterol increase: phospholipid enrichment and shift from HDL3 to HDL2 in alcohol consumers.
The reduction of cardiovascular mortality associated with moderate alcohol consumption is chiefly thought to be mediated by an increase of high density lipoprotein cholesterol (HDL-CH). This study highlights additional qualitative changes of HDL that might augment this antiatherogenic effect. In 279 healthy men, alcohol and nutrient consumption were evaluated. Groups 1 (n=62), 2 (n=172), and 3 ...
full textAssociations between small dense LDL, HDL subfractions (HDL2, HDL3) and risk of atherosclerosis in Japanese-Americans.
AIM Small dense low-density lipoprotein (sdLDL) has been suggested to be more atherogenic than large buoyant LDL. High-density lipoprotein (HDL) consists of two major subfractions (HDL2, HDL3), and just as controversy remains regarding which of the two is the more powerful negative risk factor for atherosclerosis, associations between sdLDL and these HDL subfractions are unclear. METHODS We m...
full textTorcetrapib differentially modulates the biological activities of HDL2 and HDL3 particles in the reverse cholesterol transport pathway.
OBJECTIVE Therapeutic strategies to raise low plasma HDL-cholesterol levels, with concomitant normalization of the intravascular metabolism, physicochemical properties, and antiatherogenic function of HDL particles, are a major focus in atherosclerosis prevention. METHODS AND RESULTS Patients displaying Type IIB hyperlipidemia (n=14) and healthy controls (n=11) were recruited. After drug wash...
full textA dual-precipitation method evaluated for measurement of cholesterol in high-density lipoprotein subfractions HDL2 and HDL3 in human plasma.
The dual-precipitation method for measurement of cholesterol in high-density lipoprotein subfractions HDL2 and HDL3 (Warnick et al., Clin Chem 1982;28:1574) was compared with quantification of cholesterol in HDL2 and HDL3 by zonal ultracentrifugation (Patsch et al., J Lipid Res 1974;15:356-66). For 39 plasma specimens differing widely in their HDL subfraction cholesterol concentration, the coef...
