Histone Deacetylase-3 antagonizes Aspirin-stimulated Endothelial Nitric Oxide production by reversing Aspirin-induced lysine acetylation of Endothelial Nitric Oxide Synthase

摘要

RationaleLow-dose acetylsalicylic acid (aspirin) is widely used in the treatment and prevention of vascular atherothrombosis. Cardiovascular doses of aspirin also reduce systemic blood pressure and improve endothelium-dependent vasorelaxation in patients with atherosclerosis or risk factors for atherosclerosis. Aspirin can acetylate proteins, other than its pharmacological target cyclooxygenase (COX), at lysine residues. The role of lysine acetylation in mediating the effects of low-dose aspirin on the endothelium is not known.
