Targeting Endothelial SIRT1 for the Prevention of Arterial Aging

Cardiovascular diseases are the leading cause of morbidity and mortality in the elderly population all over the world. Arterial aging is the earliest manifestation and a key risk factor for age-induced cardiovascular abnormalities. The longevity regulator Sirtuin 1 (SIRT1) is abundantly expressed in the endothelium of the arteries and elicits potent protective functions against arterial aging. Targeting endothelial SIRT1 represents a promising approach for the prevention and treatment of cardiovascular diseases. This chapter provides an overview of SIRT1’s regulation and function in endothelial cells and discusses the potential applications of targeting endothelial SIRT1 for arterial aging-related cardiovascular diseases.
