Based on the construction of the PPI network and the identification of m7G methylation genes related to MGLL, as well as the analysis using the TCGA and GTEx databases, a total of 23 genes including MGLL were found to have differential expressions in ccRCC and normal tissues (p < 0.05) (Figures 3H and 5I). This evidence concerns the gene MGLL and nonpapillary renal cell carcinoma.
