ABSTRACT
Cardiovascular diseases ( CVDs ) are the leading cause of death worldwide and pose a serious threat to human health. Silent information regulator 5 ( SIRT5 ) , which is widely distributed in cardiac myocytes, vascular smooth muscle cells and endothelial cells,as a novel deacylation-modifying enzyme,plays an important role in CVDs through deacetylation, desuccinylation and demalonylation. This review summarizes the pathophysiolog-ical mechanism of SIRT5 from the aspects of energy metabolism, regulation of inflammatory response and oxidative stress, apart from the role of SIRT5 in CVDs such as myocardial infarction, myocardial hypertrophy, arrhythmia, atherosclerosis and heart failure. This review also figures out the current research progress of SIRT5 -related inhibitors and agonists, so as to provide strategies for targeting SIRT5 to prevent and treat CVDs.
