discussions in comparison to the control of wy14643, sandoz58-035, c9 and t11-cla, epa increased the pparα mrna levels (p = 0.024, p = 0.041, p = 0.043, and p = 0.004, respectively), even though, la had no significant effect on the pparα mrna expression (p = 0.489). materials and methods this experimental study investigated the effects of c9, t11-conjugated linoleic acid (c9, t11-cla). alpha li...

background and objective: familial hypercholesterolemia (fh) is an autosomal trait, which is caused by mutations in low density lipoprotein receptor (ldlr) gene. fh penetrance is about 100% and worldwide prevalence for heterozygous subjects is almost 1 in 500 and for homozygous 1 in 1,000,000. the patients are at risk of premature coronary heart disease (chd) due to defective ldlr and hence cho...

Human epithelioid carcinoma A-431 cells are known to express unusually large numbers of receptors for the polypeptide hormone epidermal growth factor. The current studies demonstrate that this cell line also expresses 5- to 10-fold more low density lipoprotein (LDL) receptors per cell than either human fibroblasts or Chinese hamster ovary (CHO) cells. As visualized with an LDL-ferritin conjugat...

The uptake and degradation of cholesterol-rich remnant lipoproteins, referred to as beta-VLDL, are shown in the present study to be mediated by LDL receptors (apoB,E(LDL) receptors), not by unique beta-VLDL receptors. Human blood monocytes cultured for 5-7 d bound apoB- and/or apoE-containing lipoproteins from different species with affinities equivalent to those demonstrated for the receptors ...

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is an enzyme that plays a key role in regulating the circulating low density lipoprotein cholesterol (LDL-C). Among PCSK9 variants, while gain-of-function mutations aggravate degradation of LDL receptors, leading to familial hypercholesterolemia (FH), whereas loss-of-function increase receptor levels, lower and prevent coronary heart disease...

A six-year-old girl with severe hypercholesterolemia and atherosclerosis had two defective genes at the low-density-lipoprotein (LDL) receptor locus, as determined by biochemical studies of cultured fibroblasts. One gene, inherited from the mother, produced no LDL receptors; the other gene, inherited from the father, produced a receptor precursor that was not transported to the cell surface and...

The distribution of LDL receptors within subcellular compartments of isolated rat adipose cells and the effects of insulin on their expression have been assessed. By immunoblotting with specific anti-rat LDL receptor antibodies, LDL receptors were 2.3- and 4.5-fold enriched in endoplasmic reticulum-rich high-density microsomes (HDM) and Golgi complex-rich low-density microsomes (LDM), respectiv...
