Human coronary smooth muscle cells internalize versican-modified LDL through LDL receptor-related protein and LDL receptors.
Versican-like proteoglycans are the main component of the intimal extracellular matrix interacting with low density lipoprotein (LDL). The aim of this study has been to investigate the receptors involved in versican-modified LDL uptake by human vascular smooth muscle cells (VSMCs). We have found that versican-LDL interaction leads to the following: (1) monomeric LDL particles that are similar i...
متن کاملIncreased LDL cholesterol and atherosclerosis in LDL receptor-deficient mice with attenuated expression of scavenger receptor B1.
Scavenger receptor BI (SR-BI) is a multiligand cell-surface receptor that plays a central role in high density lipoprotein homeostasis in rodents. To investigate a role for SR-BI in atherosclerosis, mice with attenuated SR-BI expression were crossed with low density lipoprotein (LDL) receptor-deficient mice. Compound-homozygous mutants showed increased plasma cholesterol, surprisingly due prima...
متن کاملReactivity of direct assays for low-density lipoprotein (LDL) cholesterol toward charge-modified LDL in hypercholesterolemia.
BACKGROUND The aim of the present study was to compare 2 direct measurements for low-density lipoprotein cholesterol (LDL-C) with the Friedewald calculation (LDL-C [F]) in serum and their relationship with size-and charge-based LDL subfractions in serum ultracentrifugation fractions in patients with hypercholesterolemia (HC). METHODS AND RESULTS Serum samples from 283 HC patients who particip...
متن کاملACAT inhibition decreases LDL cholesterol in rabbits fed a cholesterol-free diet. Marked changes in LDL cholesterol without changes in LDL receptor mRNA abundance.
Rabbits fed low-fat, cholesterol-free diets containing casein as the sole protein source develop endogenous hypercholesterolemia (EH). To test the hypothesis that lipoprotein cholesteryl esters in EH rabbits are acyl coenzyme A:cholesterol acyltransferase (ACAT) derived, we treated EH rabbits with CI-976, a potent and selective ACAT inhibitor. In addition, since cholesterol and bile acid synthe...

able amounts of radiolabeled dextran in the plasma protein fraction [15]. Consequently, we do not think this mechanism plays a substantial role in producing the lower than expected dextran concentrations seen in the present study. The dextran we used had a mean molecular mass of 70 000 Da. Thus, some quantity of lower-molecular-mass dextran could have leaked out of the vascular space and distri...
