familial defective apolipoprotein (apo) b 100 (fdb) causes early-onset coronary heart diseases (chd). it is produced by r3500q mutation of the apob gene resulting in decreased binding of ldl to ldl receptor. we screened the apo b gene for r3500q mutation in 130 hypercholesterolemic patients, among whom 30 patients met criteria of familial hypercholesterolemia (fh). the prevalence of r3500q alle...

BACKGROUND Studies of the genetic and environmental influences on apolipoproteins have been conducted, but few have used data from Japanese twins. The aim of this study was to quantify and compare the genetic and environmental causes of individual differences in the serum concentrations of apolipoproteins in Japanese middle-aged twins. METHODS Apo A-I, apo A-II, apo B, apo C-II, apo C-III, an...

We have isolated and partially characterized five populations of lipoproteins from the pool of immunoisolated apoA-I-containing lipoproteins obtained from normal human plasma. The first three populations, each containing apoA-I and apoE, were isolated completely by sequential, selected affinity immunosorption against apoA-I and apoE. The lipoproteins isolated by this strategy fall into three mo...

BACKGROUND Although the link between hyperuricemia and metabolic syndrome had been recognized, the association of the dyslipidemia among individuals with hyperuricemia remains not comprehensively assessed. METHODS Using NHANES III study, we examined the relation between serum lipid profiles and different serum uric acid levels, including serum total cholesterol, LDL cholesterol, triglycerides...

The structure of truncated human apolipoprotein A-I (apo A-I), the major protein component of high density lipoprotein, has been determined at 4-A resolution. The crystals comprise residues 44-243 (exon 4) of apo A-I, a fragment that binds to lipid similarly to intact apo A-I and that retains the lipid-bound conformation even in the absence of lipid. The molecule consists almost entirely of a p...

BACKGROUND The atheroprotective effects of systemic delivery of either apolipoprotein A-I (wtApoA-I) or the naturally occurring mutant ApoA-I Milano (ApoA-IM) have been established in animal and human trials, but direct comparison studies evaluating the phenotype of ApoA-I or ApoAI-Milano knock-in mice or bone marrow transplantated animals with selectively ApoA-I or ApoAI-Milano transduced macr...

OBJECTIVE To evaluate whether lipid profile (LP), apolipoprotein A-1 (apo A-I) and malondialdehyde (MDA) have any relationship with physical exercise by comparing the groups of footballers (FG) with sedentary individuals (CG) and their relatives (RFG and RCG). SUBJECTS AND METHODS Twenty individuals from FG and CG, 60 from RFG, and 57 from RCG were studied. RESULTS FG showed lower levels of...

background: alzheimer's disease as a neurodegenerative disorder is the commonest type of dementia. a growing number of genes have been reported as the risk factors, which increase the susceptibility to alzheimer's disease. apolipoprotein e ( apoe) , which its ε4 allele has been reported as a risk factor in late onset alzheimer's disease (ad), is the main cholesterol carrier in the brain. the ma...
