Macrophage binding sites for oxidized LDL (Ox-LDL) include class A scavenger receptors (SR-As), the CD-36 molecule, and an additional but hitherto unidentified binding site. Because cell-surface glycosaminoglycans (GAGs) were previously shown to be involved in the cellular uptake of native LDL and lipoprotein(a), several strategies to assess the participation of heparan sulfate (HS) and chondro...
The addition of neutral sphingomyelinase from S. aureus to the medium of rat intestinal epithelial cell cultures (IEC-6) containing added human low density lipoprotein (LDL) resulted in two- to fivefold increases in LDL uptake and degradation. This overall effect was shown to be the combined result of sphingomyelinase activity on the composition of the LDL particle and a separate action directl...
BACKGROUND With the emergence of new lipid-lowering therapies, more patients are expected to achieve substantial lowering of low-density lipoprotein cholesterol (LDL-C). However, there are limited data examining the clinical experience of patients with low (<1.3 mmol/L) or very low (<0.65 mmol/L) levels of LDL-C. To provide information on patients with low LDL-C, we identified and characterized...
Low density lipoprotein (LDL) from patients with coronary heart disease (CHD) caused 78-286% increase in accumulation of cholesterol in human aortic subendothelial cells compared to 2-17% caused by LDL from normal subjects. Ricin-Sepharose affinity chromatography was used to separate LDL into two subfractions, one sialic acid-rich (SAR) and the other sialic acid-poor (SAP). SAP-LDL from CHD pat...
Plasma low density lipoprotein (LDL) transport kinetics were determined from the disappearance of 125I-LDL injected into age- and weight-matched groups of 13 normal subjects, 20 mild diabetics, and 8 moderately severe diabetic patients (fasting plasma glucose less than 150 and greater than 150 mg/100 ml, respectively). In mild diabetics, LDL apo-lipoprotein-B (apo-B) synthetic rate (SR) was sig...
Treatment of human aortic endothelial cells (EC) with minimally oxidized LDL (or minimally modified LDL, MM-LDL) produces a specific pattern of endothelial cell activation distinct from that produced by LPS, tumor necrosis factor-alpha, and interleukin-1, but similar to other agents that elevate cAMP. The current studies focus on the signal transduction pathways by which MM-LDL activates EC to ...
OBJECTIVES While genetic determinants of low density lipoprotein (LDL) cholesterol levels are well characterised in the general population, they are understudied in rheumatoid arthritis (RA). Our objective was to determine the association of established LDL and RA genetic alleles with LDL levels in RA cases compared with non-RA controls. METHODS Using data from electronic medical records, we ...
The objective of the present study was to evaluate the effect of a nutritional intervention promoting the Mediterranean food pattern in free-living conditions on LDL electrophoretic characteristics in a group of seventy-one healthy women, aged between 30 and 65 years. The 12-week nutritional intervention consisted of two courses on nutrition and seven individual sessions with a dietitian. The f...
