Intimal retention of cholesterol derived from apolipoprotein B100- and apolipoprotein B48-containing lipoproteins in carotid arteries of Watanabe heritable hyperlipidemic rabbits.
OBJECTIVE The arterial retention of apolipoprotein (apo) B100- and apoB48-containing lipoproteins was simultaneously determined in a rabbit model of human hypercholesterolemia using 3D confocal microscopy. METHODS AND RESULTS Lipoproteins containing apoB100 (LDL) and apoB48 (chylomicron remnants) were differentially conjugated with fluorophores and simultaneously perfused at equivalent concen...
متن کاملApolipoprotein E mimetic Peptide dramatically lowers plasma cholesterol and restores endothelial function in watanabe heritable hyperlipidemic rabbits.
BACKGROUND These studies were designed to determine whether the dual-domain peptide with a class A amphipathic helix linked to the receptor-binding domain of apolipoprotein (apo) E (Ac-hE-18A-NH2) possesses both antidyslipidemic and antiinflammatory properties. METHODS AND RESULTS A single bolus (15 mg/kg IV) of Ac-hE-18A-NH2 that contains LRKLRKRLLR (141- to 150-residue region of apo E) cova...
متن کاملHeterogeneity of N-linked sugar chains of apolipoprotein B-100 in Watanabe heritable hyperlipidemic and fasting rabbits.
We have elucidated the structures of N-linked sugar chains of human apolipoprotein (apo) B-100 (Arch Biochem Biophys 1989; 273:197-205). To investigate the role of the carbohydrate moieties of apolipoprotein B-100, we determined the structures of the N-linked sugar chains of apo B-100 purified from low density lipoprotein (LDL) of a Watanabe heritable hyperlipidemic (WHHL) rabbit and compared t...
متن کاملPartial ileal bypass reduces the production rate of low density lipoproteins in Watanabe heritable hyperlipidemic rabbits.
Partial ileal bypass surgery in homozygous Watanabe heritable hyperlipidemic (WHHL) rabbits resulted in a decrease of low density lipoproteins (LDL)-cholesterol from 14.2 +/- 2.4 to 7.0 +/- 1.2 mmol/l. To investigate the effect of partial ileal bypass on receptor-mediated and receptor-independent LDL catabolism, turnover studies were performed of radiolabeled native LDL and chemically modified ...
متن کاملAngiotensin II Destabilizes Coronary Plaques in Watanabe Heritable Hyperlipidemic Rabbits.
OBJECTIVE Increased plasma concentrations of angiotensin II (Ang II) have been implicated in many cardiovascular diseases, such as atherosclerosis, aortic aneurysms, and myocardial infarction, in humans. However, it is not known whether high levels of plasma Ang II affect coronary plaque stability and subsequent myocardial infarction. This study was designed to examine whether elevated plasma A...
