The aim of the present study was to investigate the associations between total adiposity, body fat distribution, and plasma lipoprotein levels within groups of women defined on the basis of apolipoprotein E phenotypes, in order to verify whether apoE polymorphism could modify these associations. In women having only apolipoprotein E3 isoforms (n = 24), body fat mass, the waist: hip circumferenc...

Humans express a unique subset of high-density lipoproteins (HDLs) called trypanosome lytic factors (TLFs) that kill many Trypanosoma parasite species. The proteins apolipoprotein (apo) A-I, apoL-I, and haptoglobin-related protein, which are involved in TLF structure and function, were expressed through the introduction of transgenes in mice to explore their physiological roles in vivo. Transge...

coronary artery disease. We investigated the putative role of apolipoprotein E phenotypes in cerebral infarction. Methods: The apolipoprotein E phenotypes of 69 patients (mean±SD age, 72±+11 years) who had suffered completed stroke or a transient ischemic attack and 68 sexand age-matched control subjects free of cerebrovascular disease were determined by isoelectric focusing. The relative frequ...

A non-competitive sandwich enzyme-linked immunosorbent assay for apolipoprotein C-I was developed. Sheep antibody to this apolipoprotein C-I, purified by affinity chromatography, was used for coating the wells of a microtiter plate and as a conjugate with alkaline phosphatase. The linear range of the assay was from 80 ng to 15 ng. It was sensitive down to 5 ng. The intra-assay variation coeffic...

In a prospective epidemiologic study in company employees in Westfalia aimed at improving early diagnosis of coronary heart disease in 3069 men and 1387 women, concentrations of HDL-apolipoprotein A-I and HDL-cholesterol were measured and the results were correlated with several risk factors of coronary heart disease. A negative correlation between hypertriglyceridaemia and HDL-cholesterol (r =...

BACKGROUND Dyslipidemia does not occur in all HIV-infected or antiretroviral therapy-experienced patients suggesting role of host genetic factors but there is paucity of data on association between dyslipidemia and gene polymorphisms in Zimbabwe. OBJECTIVE To determine association of lipoprotein levels and apolipoprotein B polymorphisms in HIV-infected adults. METHOD Demographic data were c...

BACKGROUND High-density lipoprotein (HDL) protects against arterial atherothrombosis, but it is unknown whether it protects against recurrent venous thromboembolism. METHODS AND RESULTS We studied 772 patients after a first spontaneous venous thromboembolism (average follow-up 48 months) and recorded the end point of symptomatic recurrent venous thromboembolism, which developed in 100 of the ...

Age-related macular degeneration (AMD) causes visual impairment in the elderly. In non-neovascular AMD, studies involving human subjects have suggested potential involvement of aberrant lipid metabolism. However, there have been no reports on gene expression patterns in animal models of non-neovascular AMD with abnormal lipid metabolism such as apolipoprotein E knockout and human apolipoprotein...

Apolipoprotein E is commonly present in systemic amyloid deposits. To investigate the possibility of using apolipoprotein E immunotargeting in the diagnosis and treatment of amyloidosis, we examined whether anti-apolipoprotein E monoclonal antibody was bound to murine amyloid deposits in vivo and whether it influenced amyloidogenesis. This study utilized a radiolabeled monoclonal antibody speci...

An oligonucleotide "melting" procedure was developed whereby we can monitor for a sequence heterogeneity in the gene for apolipoprotein E production. Two oligonucleotides were synthesized, one recognizing the common epsilon 3 allele but not the common epsilon 2 allele, the other recognizing the epsilon 2 allele but not the epsilon 3 allele. Samples from 15 subjects with different apolipoprotein...
