We have examined whether oxidized low-density lipoprotein (ox-LDL) affects the function of tissue-factor-pathway inhibitor (TFPI), an anti-coagulant regulator in the extrinsic pathway of coagulation, in cultured human umbilical vein endothelial cells (HUVEC). Treatment of culture medium of HUVEC with ox-LDL, but not with native or acetylated LDLs, drastically decreased the reactivity of TFPI to...
Oxidized LDL cholesterol (ox-LDL) is considered to be a key factor of initiating and accelerating coronary heart disease CHD diabetes Mellitus DM , associated with several mechanisms one them Oxidative stress. The aim this study was find the association between ox- ,HDL-C TG LDL-C arylesterase risk in different age groups males females difference these factors can explain sex how much changes l...
Hyperlipemia and oxidized LDL (ox-LDL) are important independent cardiovascular risk factors. Ox-LDL has been shown to stimulate vascular smooth muscle cell (VSMC) proliferation. However, the effects of hyperlipemia and the molecular mechanisms mediating hyperlipemia and ox-LDL effects on VSMC growth are poorly understood. The helix-loop-helix (HLH) transcription factor, Id3, is a redox-sensiti...
In this study we assessed whether low density lipoproteins (LDL) isolated from minced aortic atherosclerotic plaques obtained at autopsy (A-LDL) shared structural and functional properties with LDL oxidized by incubation with Cu2+ for 8-18 hours at 20 degrees C (Ox-LDL). Although both A-LDL and Ox-LDL represented monomeric particles about the size of LDL, both differed from LDL in that they sho...
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 ...
We and other groups have recently demonstrated that oxidized low density lipoprotein (Ox-LDL) induces proliferation of macrophages in vitro. Since previous immunohistochemical studies demonstrated that macrophages and macrophage derived foam cells proliferated in situ in atherosclerotic lesions, it seems reasonable to expect that the Ox-LDL-induced macrophage proliferation might be linked to th...
Stroke is the leading cause of mortality and long term disability among adults in industrialized countries. Oxidative stress is an independent risk actor by inducing production of oxygen free radicals in ischemic stroke. Because a relationship may be associated between ox-ldl and paraoxanase, the aim of this study was to investigate the association between ox-ldl and paraoxanase in ischemic str...
Oxidized low-density lipoprotein (ox-LDL) is assumed to be a major causal agent in hypercholesteraemia-induced atherosclerosis. Because the proliferation of lipid-loaden macrophages within atherosclerotic lesions has been described, we investigated the dependence of macrophage proliferation on the inhibition of inducible nitric oxide synthase (iNOS) by hypochlorite oxidized LDL. Ox-LDL induces ...
Oxidized low-density lipoprotein (ox-LDL)-induced macrophage foam cell formation and apoptosis play critical roles in the pathogenesis of atherosclerosis. Thioredoxin-1 (Trx) is an antioxidant that potently protects various cells from oxidative stress-induced cell death. However, the protective effect of Trx on ox-LDL-induced macrophage foam cell formation and apoptosis has not been studied. Th...
BACKGROUND We have recently demonstrated a lectin-like receptor for oxidized (ox)-LDL (LOX-1) in human coronary artery endothelial cells (HCAECs). This receptor is upregulated by ox-LDL. The present study examined the significance of LOX-1 in monocyte adhesion to HCAECs and endothelial injury in response to ox-LDL. METHODS AND RESULTS HCAECs were incubated in the presence of antisense oligode...
