Potential mechanisms accounting for the high cardiovascular death rates observed in Asian-Indians are dyslipidemia and insulin resistance. Polymorphisms in the APOC3 promoter (-455 T/C and -482 C/T) were frequently encountered in young Asian-Indians and they correlated with reduced concentrations of apolipoprotein A-I.
Three patients with recurrent vascular catheter-related bacteremia were successfully treated by allowing a solution of minocycline and ethylenediaminetetraacetate (EDTA) to dwell in the lumen of the indwelling catheter or by coating polyurethane catheters with minocycline/EDTA and flushing the lumen daily with the same solution. In vitro and in vivo(More)
PURPOSE OF REVIEW To review gene regulation of HDL-cholesterol and discuss molecular abnormalities in HDL candidate genes that may lead to human pathologic states. RECENT FINDINGS The inverse association between HDL-cholesterol and vascular disease, especially coronary heart disease, has long been recognized, but understanding gene regulation of HDL in(More)
BACKGROUND Despite the growing epidemic of the metabolic syndrome (MetS), few studies have evaluated genetic polymorphisms associated with the MetS phenotype. One candidate, APOC3, modulates lipid and lipoprotein metabolism and the promoter polymorphisms C-482T/T-455C are associated with loss of insulin downregulation. METHODS One hundred twenty two(More)
The ATP-binding cassette transporter, ABCA1, is a member of the ABC superfamily of proteins involved in the active transport of substrates across cellular membranes. Recent studies have implicated mutations in ABCA1 as the cause of Tangier disease (TD) and familial hypoalphalipoproteinemia (FHA). To evaluate the molecular basis of low high density(More)
High levels of high-density lipoprotein cholesterol (HDL-C) occur with cholesteryl ester transfer protein (CETP) deficiency. However, the extent to which CETP deficiency states may be associated with protection against coronary artery disease (CAD) has been controversial. We evaluated a Greek pedigree with high levels of HDL-C and no history of premature(More)
Although popular diets focus on weight loss and their favorable biochemical and physiological effects, fewer investigations have evaluated the biological impact of these diets during weight maintenance. To study this issue, three popular diets-Atkins, South Beach, and Ornish-were tested in a randomized and counterbalanced crossover study between January and(More)
Low HDL-cholesterol (HDL-C) concentrations are inversely correlated with cardiovascular disease, and previous studies have demonstrated that variants in the ATP-binding cassette transporter, ABCA1, are responsible for a proportion of HDL-C deficiency states. We identified a novel variant in ABCA1 in a kindred with decreased HDL-C. This variant was not(More)
The recent discovery of an ATP-binding cassette transporter, ABCA1, as an important regulator of high density lipoprotein (HDL) metabolism and reverse cholesterol transport has facilitated the identification of novel variants associated with HDL cholesterol deficiency states. We identified a subject with HDL cholesterol deficiency (4 mg/dl) who developed(More)
Recent studies have implicated mutations in the ATP-binding cassette transporter A1, ABCA1, as a cause of Tangier disease (TD) and familial hypoalphalipoproteinemia (FHA). We investigated a proband with very low levels of high-density lipoprotein cholesterol (HDL-C, 6 mg/dL) and a history of premature coronary heart disease (CHD). Sequencing of the ABCA1(More)
