Analysis of the TCGA-KIRC database suggested that elevation of METTL3, IGF2BP1, IGF2BP2, and IGF2BP3 and decreased expressions of ALKBH5, FTO, METTL14, YTHDF2, YTHDC1, YTHDC2, ZC3H13, METTL16, KIAA1429, CBLL1, and RBM15 in ccRCC were associated with poor OS probability. Here, METTL3 is linked to nonpapillary renal cell carcinoma.
