    N6-Methyladenosine on mRNA Facilitates a Phase-Separated Nuclear Body That Suppresses Myeloid Leukemic Differentiation

    The authors found that YTHDC1 was the essential N6-Methyladenosine (m6A) reader in myeloid leukemia from a genome-wide CRISPR screen and that m6A was required for the formation of a nuclear body mediated by phase separation that maintained mRNA stability and controlled cancer cell survival and differentiation.
