The proposed ligand binding domain of the low density lipoprotein (LDL) receptor consists of a 40-amino acid cysteine-rich unit that is repeated with some variation seven times. We describe here a mutant allele at the LDL receptor locus in which one of the seven repeats has been deleted. This mutation was found in a patient with the clinical syndrome of homozygous familial hypercholesterolemia....

Familial combined hyperlipidemia (FCHL) is a common inherited lipid disorder, affecting 1 to 2 percent of the population in Westernized societies. Individuals with FCHL have large quantities of very low density lipoprotein (VLDL) and low density lipoprotein (LDL) and develop premature coronary heart disease. A mouse model displaying some of the features of FCHL was created by crossing mice carr...

Background: Coronary artery disease today is a major contributor to mortality and morbidity from cardiovascular disease. The drug, interventional and surgical methods are used to treat coronary artery stenosis. Statins are the most commonly used drugs for stenosis and coronary artery disease. Low-density lipoprotein (LDL) The purpose of this study was to evaluate the effect of atorvastatin on L...

The very low-density lipoprotein (VLDL) receptor is a member of the low-density lipoprotein (LDL) receptor family. In vitro and in vivo studies have shown that VLDL receptor binds triglyceride (TG)-rich lipoproteins but not LDL, and functions as a peripheral remnant lipoprotein receptor. VLDL receptor is expressed abundantly in fatty acid-active tissues (heart, skeletal muscle and fat), the bra...

The aim of this study is to determine the prevalence of unrecognized dyslipidaemia and a specific correlation between lipid values and age, gender or ethnic origin in the study population. This retrospective cross-sectional study included 311 subjects who had their lipid profiles checked for the first time in a private hospital in Dubai in a six month - period. The analysis shows an increased p...

Abstract Familial hypercholesterolemia (FH) is a hereditary dislipidemia. Patients present with extremely high level of low-density lipoprotein cholesterol (LDL-C), which is due to mutation in the gene of LDL receptor. Homozygous patients (HoFH) whose incidence is 1 in 1.000.000 are at high risk of premature aortic valve stenosis, and coronary artery atherosclerosis. In homozygous individual...

Macrophages possess a number of surface receptors that are capable of mediating the internalization of lipoproteins. The low-density lipoprotein (LDL) receptor of human monocyte macrophages recognizes apolipoprotein B-100 and apolipoprotein E and is rapidly regulated in response to changes in intracellular cholesterol levels. In contrast, in J774 macrophages LDL receptor regulation is defective...

oxidation of low density lipoprotein (ldl) has been strongly implicated in the phathogenesis of atherosclerosis. the use of oxidants in dietary food stuff may lead to the production of oxidized ldl and may increase both the development and the progression of atherosclerosis. the present work investigated the effects of some elements including: copper (cu), iron (fe), vanadium (v) and titanium (...
