We describe a disorder in which low-density lipoprotein (LDL)-cholesterol and apolipoprotein B are in low concentration (0.47 mmol/L and 0.28 g/L, respectively) and chylomicrons are still present in plasma after an 18-h fast. The d less than 1.006 fraction was isolated by flotation ultracentrifugation and the apolipoproteins were analyzed by electrophoresis, immunoblotting with anti-apolipoprot...

Radioiodinated apolipoprotein E, added in small amounts to rat serum, rapidly associates with the serum very low density lipoproteins and high density lipoproteins in proportion to their content of endogenous and apolipoprotein E. The labeled lipoproteins can be separated, without ultracentrifugation, by molecular sieve chromatography. When these labeled lipoproteins are injected intravenously ...

Many genes are hypothesized to be involved in determining an individual's risk for coronary artery disease (CAD). Recent efforts have focused on the genetic architecture of quantitative traits related to risk for CAD. Studies relating genetic variation in the structural gene for apolipoprotein E to plasma levels of apolipoprotein E illustrate strategies to begin to understand the genetic archit...

Although some previous studies have suggested that triglyceride, a major core lipid, plays a key role in the assembly and secretion of apolipoprotein B-containing lipoproteins from HepG2 cells, other reports have indicated the importance of cholesteryl ester, another core lipid. We attempted to better define the roles of triglyceride and cholesteryl ester in the assembly and secretion of apolip...

introduction: hyperlipidemia is a risk factor for atherosclerosis and cardiovascular diseases. nuts such as almonds are high in unsaturated lipids and antioxidants. some studies indicate that nuts have beneficial effects on cardiovascular system. therefore, the aim of this study was evaluation of the effectiveness of shelled almonds on reduction of blood lipid and lipoprotein levels in hyperlip...

background: we aimed here to investigate the association between alleles and genotypes of apoe and age-related macular degeneration (amd) development. materials and methods: after ophthalmological examination, 120 patients with confirmed amd and 120 healthy controls were enrolled in the study. the polymorphic segment of apoe gene was pcr-amplified and sequenced to determine the frequency distri...

High density lipoproteins of rat blood plasma were labeled in vitro with radioiodinated apolipoprotein E and biologically with [3H]cholesteryl esters. These two components, present in high density lipoproteins separated from serum of normal or cholesterol-fed rats by molecular sieve chromatography, were removed slowly from perfused livers and the labeled apolipoprotein E was also removed slowly...

We describe here two patients, M. P. and S. L., with recessive abetalipoproteinemia. Analysis of restriction fragments of DNA from both patients using cDNA probes spanning the entire apolipoprotein B gene revealed no major insertions or deletions. Further, as defined by restriction fragment length polymorphism, abetalipoproteinemia, in these patients, did not appear associated with particular a...

b a ckground: the objective was to investigate the relationship between serum interleukin-18 (il-18), pentraxin 3 (ptx3), and high-sensitivity c-reactive protein (hs-crp) levels with body mass index (bmi) and abdominal obesity and also the interaction between genetic variants of apolipoprotein a-ii (apo a-ii) and obesity on the levels of these factors in type 2 diabetes patients (t2d). m ethods...

multiple sclerosis (ms) is a chronic inflammatory disorder of the central nervous system, with a complex etiology that includes a strong genetic component. the chromosome 19q 13 region surrounding the apolipoprotein e (apoe) gene has shown consistent evidence of involvement in ms. in a cross-sectional study, to show the apoe genotype and allele frequency in the ms population of iran in comparis...
