The recent investigations have extensively focused on the importance of sirtuins, as a highly conserved family of gene products, particularly SIRT3 in various biological and pathological processes. SIRT3, the mitochondrial NAD+-dependent deacetylase has been demonstrated to target a broad range of proteins involved in the oxidative stress, ischemia-reperfusion injury, mitochondrial metabolism homeostasis and cellular death. The critical function of SIRT3 in myocardial infarction (MI), which is one of the complex phenotype of coronary artery disease and a result of interaction between various genetic and environmental factors, as well as in cardiac repair and remodeling post-MI have attracted more attention in the recent years. Therefore, in this review, we will summarize important literature about the involvement of SIRT3 in cardiac remodeling/repair following MI and its potential underlying mechanisms.
Keywords: Cardiac remodeling/repair; Coronary artery disease; Myocardial infarction; Sirtuins.
