Abstract: N6-methyladenosine (m6A) is a prevalent modification of RNA in eukaryotes,
bacteria, and viruses. It is highly conserved and can affect the structure, localization, and
biology functions of RNA. In recent years, multiple m6A methylation sites have been identified
in the viral RNA genome and transcripts of DNA viruses. This modification occurs commonly
during the primary infection and is dynamically regulated by a methyltransferase (writers),
demethylase (eraser) and m6A-binding proteins (readers) within the host cells. The abnormal
m6A modification not only affects the replication of pathogenic viruses and host immune
response but also contributes to the pathogenesis of virus-induced cancers. In this review, we
highlight recent advances on the mechanism of m6A modification on viral replication, host
immune response and carcinogenesis to provide a novel insight for epigenetic prevention of
viral infection and virus-driven carcinogenesis.
