Regulation of Sirtuins in Sepsis-Induced Myocardial Damage: The Underlying Mechanisms for Cardioprotection

Abstract

Sepsis is defined as “a life-threatening organ dysfunction caused by a dysregulated host response to infection”. Although the treatment of sepsis has evolved rapidly in the last few years, the morbidity and mortality of sepsis in clinical treatment are still climbing. Sirtuins (SIRTs) are a highly conserved family of histone deacetylation involved in energy metabolism. There are many mechanisms of sepsis-induced myocardial damage, and more and more evidence show that SIRTs play a vital role in the occurrence and development of sepsis-induced myocardial damage, including the regulation of sepsis inflammation, oxidative stress and metabolic signals. This review describes our understanding of the molecular mechanisms and pathophysiology of sepsis-induced myocardial damage, with a focus on disrupted SIRTs regulation. In addition, this review also describes the research status of related therapeutic drugs, so as to provide reference for the treatment of sepsis.
