[Advances in m A modification and its regulation of viral replication].

N -methyladenosine (m A) is a prevalent modification of RNA in eukaryotes and plays an important role in the process of mRNA translocation, stabilization and translation. m A exerts different influences on the viral replication cycle, and both viral replication and host immune response to the virus are affected by m A. In this review, we summarize recent studies on the mechanism of m A modification and its effects on viral replication and host immune response, in order to provide a reference for epigenetic regulation in the viral life cycle.
