The role of sirtuins in the regulation of reactive oxygen species in myocardial ischemia/reperfusion injury.

Myocardial ischemia/reperfusion (I/R) injury has high morbidity and mortality rates, posing a significant burden on society. There is an urgent need to understand its pathogenesis and develop effective treatments. Reactive oxygen species (ROS) are crucial for the development of myocardial I/R injury, and inhibiting ROS overproduction is one of the most critical ways to delay myocardial I/R injury. Sirtuins are a group of nicotinic adenine dinucleotide ( +)-dependent histone deacetylases whose members can regulate ROS by modulating various biological processes. Numerous studies have shown that Sirtuins play an essential role in the progression of myocardial I/R injury by regulating ROS. This study focuses on the relationship between myocardial I/R injury and ROS, Sirtuins and ROS, discusses the role of Sirtuins in regulating ROS in myocardial I/R, and summarizes the therapeutic modalities aimed at targeting Sirtuins to modulate ROS in myocardial I/R injury, thereby guiding future research endeavors.
