Abstract

Chemical modifications of RNA provide a direct and rapid way to modulate the existing transcriptome, allowing the cells to adapt rapidly to the changing environment. Among these modifications, N⁶-methyladenosine (m⁶A) has recently emerged as a widely prevalent mark of messenger RNA in eukaryotes, linking external stimuli to an intricate network of transcriptional, post-transcriptional and translational processes. m⁶A modification modulates a broad spectrum of biochemical processes, including mRNA decay, translation and splicing. Both m⁶A modification and the enzymes that control m⁶A metabolism are essential for normal development. In this review, we summarized the most recent findings on the role of m⁶A modification in maintenance of the pluripotency of embryonic stem cells (ESCs), cell fate specification, the reprogramming of somatic cells into induced pluripotent stem cells (iPSCs), and differentiation of stem and progenitor cells.
