Ribonucleic acid (RNA) is one of the fundamental molecules essential for gene expression in all known forms of life. Moreover, accumulated studies had identified diverse RNA modification (minor changes to the chemical composition of RNA molecules) and highlighted their biological significance for regulating gene expression. However, the precise role of distinct RNA modifications in various biological processes remain incompletely understood, waiting for further investigations. To fill in these knowledge gaps, this study utilized in vitro cultured cell model to dig deep into how N6-methyladenosine (m6A), the most abundant internal modification in eukaryotic messenger RNA (mRNA), regulates two critical developmental stages, pluripotency regulation and subsequent primordial germ cell (PGC) specification, in early mouse embryo. This study found that m6A is required for maintaining pluripotency via modulating Erk and Akt pathways while it also safeguards PGC lineage commitment via suppressing ERas-Akt pathway. In summary, these results uncover the pivotal role of signaling pathways in m6A mediated regulation during early embryogenesis. Furthermore, this study together with numerous future ones may lay out a conceptual foundation which could bring us closer to developing therapeutical approaches by targeting RNA modifications.
