چکیده

objective(s):resveratrol (res) is a polyphenol compound that has been shown a promising cardioprotective effect. however, some reports have yielded conflicting findings. herein, we investigated the anti-atherosclerotic effects of res in apolipoprotein e (apo e)-deficient mice on a high cholesterol diet. materials and methods: firstly, atherosclerosis was induced by feeding a high cholesterol diet to apo e-deficient mice. then, we examined its effects on weight control, and serum interleukin-6 (il-6) levels and used histopathological methods to analyze morphology and inflammatory marker of atherosclerotic lesions in mice orally supplemented with high (25 mg/kg/day) and low (5 mg/kg/day) doses of res for 8 weeks. results: mice with high dose of res had reduced epididymal fat pads, and lower serum il-6 levels compared with those of control mice. moreover, res in high doses also decreased the low-density lipoprotein cholesterol (ldl-c) levels and atherogenic index (ldl-c/hdl-c) in the mice. dissection of high-dose res-treated mice revealed a marked reduction in fat deposition, percentage of mice with atherosclerotic lesion, and intima/media ratio in the aortic areas.theexpressions of macrophage-specific marker f4/80 and cardiovascular inflammatory marker nf-κb in atherosclerotic vessels were both diminished in the atherosclerotic vessels of high-dose res-supplementated apo e-deficient mice. conclusion: these results suggest that res prevented the effects of a high cholesterol diet onthe rate of accretion in atherosclerosis progression by reducing the ldl-c levels and suppressing atherosclerotic inflammation. res can therefore be valuable in the development of new anti-atherosclerotic agents.

Effect of apolipoprotein E phenotype on diet-induced lowering of plasma low density lipoprotein cholesterol.

The National Cholesterol Education Program (NCEP) has recommended that dietary total fat, saturated fat, and cholesterol intake be reduced to < or = 30% of calories, < 10% of calories, and < 300 mg/day, respectively (Step 1 diet) in the general population to reduce plasma low density lipoprotein (LDL) cholesterol levels and heart disease risk. We examined the LDL cholesterol-lowering response t...

Allergic lung inflammation promotes atherosclerosis in apolipoprotein E-deficient mice.

Inflammation drives asthma and atherosclerosis. Clinical studies suggest that asthmatic patients have a high risk of atherosclerosis. Yet this hypothesis remains uncertain, given that Th2 imbalance causes asthma whereas Th1 immunity promotes atherosclerosis. In this study, chronic allergic lung inflammation (ALI) was induced in mice by ovalbumin sensitization and challenge. Acute ALI was induce...

Resveratrol Protects Rabbits Against Cholesterol Diet-Induced Hyperlipidaemia.

The excessive consumption of high cholesterol diet has been associated with an increased incidence oflipidaemia. Lipidaemia is enhanced by formation of oxidative stress, lipid peroxidation and hyperglycaemia. The aim ofthese experiments was to investigate the protective effect of resveratrol co-administered with cholesterol diet inducedhyperlipidaemia in rabbits. Thirty rabbits divided into six...

Overexpressed lipoprotein lipase protects against atherosclerosis in apolipoprotein E knockout mice.

Lipoprotein lipase (LPL) is known to play a crucial role in lipoprotein metabolism by hydrolyzing triglycerides; however its role in atherogenesis has yet to be determined. We have previously shown that low density lipoprotein receptor knockout mice overexpressing LPL are resistant to diet-induced atherosclerosis due to the suppression of remnant lipoproteins. Plasma lipoproteins and atheroscle...
