N6-methyladenosine (m6A) is one of the most abundant internal mRNA modifications, and it affects multiple biological processes related to eukaryotic mRNA. The majority of m6A sites are located in stop codons and 3′UTR regions of mRNAs. m6A regulates RNA metabolism, including alternative splicing (AS), alternative polyadenylation (APA), mRNA export, decay, stabilization, and translation. The m6A metabolic pathway is regulated by a series of m6A writers, erasers and readers. Recent studies indicate that m6A is essential for the regulation of gene expression, tumor formation, stem cell fate, gametogenesis, and animal development. In this systematic review, we summarized the recent advances in newly identified m6A effectors and the effects of m6A on RNA metabolism. Subsequently, we reviewed the functional roles of RNA m6A modification in diverse cellular bioprocesses, such as stem cell fate decisions, cell reprogramming and early embryonic development, and we discussed the potential of m6A modification to be applied to regenerative medicine, disease treatment, organ transplantation, and animal reproduction.
