Oxidized low-density lipoprotein in postmenopausal women.
BACKGROUND Oxidized low-density lipoprotein (oxLDL) leads to atherosclerosis and cardiovascular disease, the most frequent causes of death worldwide. After menopause, lipid and lipoprotein metabolism changes and women are at greater risk of cardiovascular disease compared to fertile women. The aim of this study was to determine the prevalence of serum oxLDL in postmenopausal women and to identi...
متن کاملplasma level of oxidized low- density lipoprotein in macroalbuminuric
accumulating evidence suggest that in patients with diabetes mellitus, increased rate of lipoprotein oxidation and oxidative stress have important role in diabetic angiopathy, including nephropathy. to evaluate the association of oxidized low- density lipoprotein (ox-ldl) with the development of diabetic nephropathy, plasma level of ox-ldl were measured in 70 diabetic patients with macro and 63...
متن کاملA macrophage receptor that recognizes oxidized low density lipoprotein but not acetylated low density lipoprotein.
The formation of cholesterol-loaded macrophage foam cells in arterial tissue may occur by the uptake of modified lipoproteins via the scavenger receptor pathway. The macrophage scavenger receptor, also called the acetylated low density lipoprotein (Ac-LDL) receptor, has been reported to recognize Ac-LDL as well as oxidized LDL species such as endothelial cell-modified LDL (EC-LDL). We now repor...
متن کاملNon-oxidative modification of native low-density lipoprotein by oxidized low-density lipoprotein.
The oxidative modification of low-density lipoprotein (LDL) has been implicated in the pathogenesis of atherosclerosis, although little is known as yet about the precise mechanism of oxidation in vivo. The studies presented here demonstrate that, in the absence of cells or transition metals, oxidized LDL can modify native LDL through co-incubation in vitro such as to increase its net negative c...
متن کاملOxidized low-density lipoprotein induces calpain-dependent cell death and ubiquitination of caspase 3 in HMEC-1 endothelial cells.
Oxidized low-density lipoprotein (oxLDL) is known to induce apoptosis in endothelial cells, and this is believed to contribute to the progression of atherosclerosis. In the present study we made the novel observation that oxLDL-induced death of HMEC-1 cells is accompanied by activation of calpain. The mu-calpain inhibitor PD 151746 decreased oxLDL-induced cytotoxicity, whereas the general caspa...
