YTHDC2 and neoplasm: Next, we analyzed the mRNA expression differences of m6A regulatory genes in tumor and normal tissues, as well as in different stages of tumors (Fig. 2D), with ELAVL1, FMR1, HNRNPA2B1, IGF2BP3, YTHDC2, YTHDF2, EIF3A, RBMX, RBM15, and WTAP showing stage-specific expression (Fig. S1D).
