Resveratrol activates Sirtuin 1 (SIRT1), a nicotinamide adenine dinucleotide-dependent deacetylase which modulates metabolic homeostasis and improves several pathophysiological features present in diseases of ageing. In particular, it has been shown that SIRT1 activation improves endothelial dysfunction and suppresses vascular inflammation, two central pathophysiological processes involved in the initiation and progression of cardiovascular disease. The downstream targets of SIRT1 activation in this context, however, remain poorly defined. Therefore, in this study, we aimed to characterize mechanistically how SIRT1 activation regulates the endothelial vasoprotective phenotype.
