Oxidation of low-density lipoprotein (LDL), the major cholesterol-carrying protein in human blood plasma, is now commonly implicated as an initiator of atherosclerosis [1]. Oxidation of the lipid moiety appears to be a key event in the process preceding the modification of apolipoprotein B-100, eventual uptake of the lipoprotein by macrophages and the formation of foam cells [2]. A key piece of...
The hypothesis that oxidized LDL (ox-LDL) is necessary, if not obligatory, in the development of atherosclerotic lesions was formulated .20 years ago with the seminal observation that uptake of native LDL by macrophages did not result in foam cell formation. In contrast, uptake of ox-LDL via scavenger receptors resulted in the unregulated accumulation of lipid.1 Since then, multiple studies in ...
[Purpose] This study examined the effects of a 12-week exercise program on plasma level of oxidized low-density lipoprotein cholesterol in obese elderly women, who are at increased risk of heart disease morbidity. [Subjects and Methods] Twenty participants were assigned into either a control (n = 10) or a supervised exercise program (n = 10) group. The 12-week exercise intervention was performe...
Oxidized LDL (OxLDL) is a proatherogenic lipoprotein, accumulating in the vascular wall and contributing to the pathogenesis of vascular dysfunction early in the development of atherosclerosis. Enhanced serum levels of OxLDL, as well as antibodies against its epitopes, are predictive for endothelial dysfunction and coronary heart disease. While enhanced oxidative stress is one factor triggering...
Oxidized low-density lipoprotein (ox-LDL) is critical to atherosclerosis in hyperlipidemia. Bone marrow (BM)-derived endothelial progenitor cells (EPCs) are important to preventing atherosclerosis, and significantly decreased in hyperlipidemia. This study was to demonstrate ox-LDL and hyperlipidemia could exhibit similar effect on EPC population and the role of reactive oxygen species (ROS). RO...
