Then, we extracted the expression of 19 m6A-related regulators (METTL3, VIRMA, METTL14, ZC3H13, RBM15, RBM15B, WTAP, HNRNPC, YTHDC1, HNRNPA2B1, YTHDC2, IGF2BP1, YTHDF1, IGF2BP2, YTHDF2, IGF2BP3, YTHDF3, ALKBH5, and FTO) from The Cancer Genome Atlas (TCGA) (https://portal.gdc.cancer.gov/). Here, YTHDF2 is linked to cancer.
