We analyzed the mRNA expression levels of 13 m6A-related genes (METTL3, METTL14, WTAP, RBM15, ZC3H13, KIAA1429, FTO, ALKBH5, YTHDC1, YTHDC2, YTHDF1, YTHDF2, HNRNPC) in TCGA database to identify the different expressed genes between ccRCC tissues and normal tissues. This evidence concerns the gene HNRNPC and nonpapillary renal cell carcinoma.
