Some m6A regulators are preferred to negatively related to most of the stemness factors such as METTL14, RBM15, and WTAP in BLCA; METTL14, RBM33, YTHDC1, YTHDC2, ZC3H13, and ZCCHC4 in BRCA; ALKBH5, FTO, and RBFOX2 in COAD; YTHDC2 in LUAD; CBLL1, HNRNPC, IGF2BP2, METTL16, and YTHDC1 in LIHC; FTO in LAML; METTL14 and YTHDC2 in PAAD; RBFOX2 in PCPG; FTO and RBFOX2 in STAD; and FMR1, FTO, IGF2BP2, IGF2BP3, METTL14, RBFOX2, and RBM15B in TGCT (Supplementary Figure S8). This evidence concerns the gene RBFOX2 and bladder transitional cell carcinoma.
