N(6)-methyladenosine modification: A vital role of programmed cell death in myocardial ischemia/reperfusion injury

Abstract

N(6)-methyladenosine (m6A) modification is closely associated with myocardial ischemia/reperfusion injury (MIRI). As the most common modification among RNA modifications, the reversible m6A modification is processed by methylase ("writers") and demethylase ("erasers"). The biological effects of RNA modified by m6A are regulated under the corresponding RNA binding proteins (RBPs) ("readers"). m6A modification regulates the whole process of RNA, including transcription, processing, splicing, nuclear export, stability, degradation, and translation. Programmed cell death (PCD) is a regulated mechanism that maintains the internal environment's stability. PCD plays an essential role in MIRI, including apoptosis, autophagy, pyroptosis, ferroptosis, and necroptosis. However, the relationship between PCD modified with m6A and MIRI is still not clear. This review summarizes the regulators of m6A modification and their bioeffects on PCD in MIRI.

Keywords: Myocardial ischemia/reperfusion injury; Programmed cell death; m(6)A modification.
