Statins are widely used in the treatment of dyslipidemia and associated cardiovascular abnormalities including atherosclerosis, hypertension and coronary heart disease. Needless to mention, statins have cholesterol-lowering effects by means of inhibiting 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase, a rate-limiting enzyme of cholesterol biosynthesis. Besides cholesterol-lowering effects, statins possess pleiotropic anti-inflammatory, anti-oxidant, anti-platelet and anti-fibrotic properties, which may additionally play imperative roles in statins-mediated cardiovascular protection. However, the precise mechanisms involved in the cardiovascular defensive potential of statins have not completely been elucidated. Intriguingly, a considerable number of studies demonstrated the potential modulatory role of statins on endothelial nitric oxide synthase (eNOS), a key enzyme involved in the regulation of …
