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...

We determined the common polymorphism of apolipoprotein E (E2, E3, and E4), apolipoprotein B Xba I polymorphism, and apolipoprotein C-III Sst I polymorphism in almost all Finnish centenarians alive in 1991 (n = 179/185). Plasma lipid and lipoprotein levels in different apolipoprotein genotypes were also measured. In comparison with younger Finnish populations studied previously, the frequency o...

The expression of apolipoprotein E in cultured neonatal rabbit aortic smooth muscle cells was examined. Northern blot analysis determined that there was a single RNA transcript of approximately 1.2 kb. Moreover, a polyclonal antibody against rabbit apolipoprotein E was prepared in a goat and used in immunoprecipitations to demonstrate that the cultured cells secreted apolipoprotein E into the m...

It is becoming increasingly accepted that removal of cellular cholesterol occurs by at least two pathways, one involving the well-described aqueous diffusion mechanism and another promoted by lipid-free apolipoproteins. We compared the contribution of apolipoprotein-dependent and -independent pathways, taking into consideration the influence of cellular metabolism, on cholesterol efflux promote...

The apolipoprotein E ε4 gene is the most important genetic risk factor for sporadic Alzheimer's disease, but the link between this gene and neurodegeneration remains unclear. Using array tomography, we analysed >50000 synapses in brains of 11 patients with Alzheimer's disease and five non-demented control subjects and found that synapse loss around senile plaques in Alzheimer's disease correlat...
