Epitranscriptomic m6A modification in the stem cell field and its effects on cell death and survival.

The reversible N6-methyl-adenosine (m6A) modification of messenger RNAs (mRNAs) has generated much interest in the field of stem cell modulation in recent years. Meanwhile, mounting evidence has shown that many physiopathological processes concerning cell death and survival harbor this chemical mark. Our review provides an overview of the m6A epitranscriptomic field and the updated mechanisms of m6A decoration in stem cell regulation. Furthermore, we focus on the role of m6A in DNA damage and the immune response, cell apoptosis, autophagy, and senescence, followed by recent advancements in m6A-induced viral replication. The function of abundant RNA-binding proteins (RBPs) identified in m6A regulatory systems will also be discussed in this review, highlighting their far-reaching implications in cellular m6A machinery and disease treatment.
