Thus, we studied the expression and mutations of 20 main m6A regulators (eight m6A writers: METTL3, METTL14, WTAP, RBMX, RBM15, RBM15B, VIRMA, and ZC3H13; two m6A erasers: FTO and ALKBH5; and ten m6A readers: YTHDF1, YTHDF2, YTHDF3, YTHDC1, YTHDC2, HNRNPA2B1, EIF3A, IGF2BP1, IGF2BP2, and IGF2BP3) in data from patients with pancreatic cancer in TCGA and various public databases [13]. The gene discussed is YTHDC2; the disease is pancreatic neoplasm.
