Hsa-Let-7g miRNA Targets Caspase-3 and Inhibits the Apoptosis Induced by ox-LDL in Endothelial Cells
It has been well confirmed ox-LDL plays key roles in the development of atherosclerosis via binding to LOX-1 and inducing apoptosis in vascular endothelial cells. Recent studies have shown ox-LDL can suppress microRNA has-let-7g, which in turn inhibits the ox-LDL induced apoptosis. However, details need to be uncovered. To determine the anti-atherosclerosis effect of microRNA has-let-7g, and to...
OBJECTIVES To measure circulating levels of oxidized-low-density lipoproteins (ox-LDL) in patients with stable and unstable angina and controls, and to investigate their correlation with the extent of coronary artery disease (CAD) and the presence of complex plaques at coronary angiography. METHODS AND RESULTS Circulating ox-LDL were assessed, using ELISA, in patients with unstable angina (UA...
It is postulated that macrophage-derived foam cells accumulate in the arterial wall because they lose the ability to migrate after excessive ingestion of modified forms of low-density lipoproteins (LDL). To assess changes in locomotor force generating capacity of foam cells, we measured isometric forces in J774A.1 macrophages after cholesterol loading with oxidized (Ox-LDL) or aggregated (Agg-L...
BACKGROUND Oxidative modification of low density lipoproteins (LDL) convert these native particles into pathogenic, immunogenic and atherogenic particles. Factors enhance LDL oxidation are poorly understood, especially in conditions of hyperglycemia. The present study was conducted to investigate which metabolic conditions are associated with the promotion of LDL oxidation in different glycemic...
زمینه و هدف: چاقی و افزایش شاخصهای التهابی از جمله آمیلوئید A (SAA) و LDL اکسید شده (Ox-LDL)، از عوامل اصلی ابتلای به بیماریهای قلبی - عروقی است و فعالیتهای ورزشی اثر مثبتی در کاهش عوامل خطرزای این بیماریها دارد. هدف از پژوهش حاضر، ارزیابی اثر یک جلسه تمرین استقامتی روی چرخ کارسنج بر سطوح خونی SAA و Ox-LDL در مردان جوان چاق بود. مواد و روش کار: تعداد 22 مرد جوان در این مطالعه شرکت کردند که...
BACKGROUND/AIM The objective of our study was to analyze the lipid profile and some risk factors of atherosclerosis such as oxidized-low density lipoprotein (ox-LDL), small dense LDL (sd LDL) in the offspring of patients with premature coronary heart disease (CHD). POPULATION AND METHODS Children whose parents had early onset CHD were matched with age and sex pairs. Study and controls were an...
BACKGROUND This study aimed to determine the association of lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) activity in circulation and peripheral blood mononuclear cells (PBMCs) with inflammatory and oxidative stress markers in nonobese women and according to menopausal status. Lp-PLA(2) activity, a marker for cardiovascular risk is associated with inflammation and oxidative stress. ME...
Recent data suggest that the lectin-like oxidized low-density lipoprotein (ox-LDL) receptor-1 (LOX-1)/ox-LDL system may be involved in the pathogenesis of arthritis. We aimed to demonstrate the roles of the LOX-1/ox-LDL system in arthritis development by using LOX-1 knockout (KO) mice. Arthritis was induced in the right knees of C57Bl/6 wild-type (WT) and LOX-1 KO mice via zymosan injection. Sa...
C-reactive protein (CRP) is a cyclic pentameric protein whose major binding specificity, at physiological pH, is for substances bearing exposed phosphocholine moieties. Another pentameric form of CRP, which exists at acidic pH, displays binding activity for oxidized LDL (ox-LDL). The ox-LDL-binding site in CRP, which is hidden at physiological pH, is exposed by acidic pH-induced structural chan...
BACKGROUND Ethanol extract of propolis (EEP), rich in flavones, has been known for various biological activities including antioxidant, antiinflammatory and antibiotic activities. Our previous studies have shown that EEP protects endothelial cells from oxidized low-density lipoprotein (ox-LDL)-induced apoptosis and inhibits atherosclerotic lesion development. In this present study, we explored ...
