简介
N 6-methyladenosine (m 6 A) RNA modification, a dynamic and reversible process, is essential for tissue development and pathogenesis. However, the potential involvement of m 6 A in the regulation of cardiomyocyte (CM) proliferation and cardiac regeneration remains unclear. In this study, we aimed to investigate the essential role of m 6 A modification in heart regeneration during postnatal and adult injury.
Methods and results: In this study, we identified the downregulation of m 6 A demethylase ALKBH5, an m6A “eraser” that is responsible for increased m 6 A methylation, in the heart after birth. Notably, ALKBH5 knockout mice exhibited decreased cardiac regenerative ability and heart function after neonatal apex resection. Conversely, forced expression of ALKBH5 via adeno-associated virus-9 (AAV9) delivery markedly reduced the infarct size, restored cardiac function and promoted CM proliferation after …
