KEGG pathways such as hsa00020 (citrate cycle (TCA cycle)), hsa00190 (oxidative phosphorylation), hsa00010 (glycolysis/gluconeogenesis) and hsa00620 (pyruvate metabolism) were correlated with the functions of the genes similar to Musashi-2 in ccRCC. This evidence concerns the gene MSI2 and nonpapillary renal cell carcinoma.
