Based on our findings, we conclude that PI3K-Akt, Foxo, endocytosis, MAPK, Tight junction, and cytokine-cytokine receptor interaction pathways are among the most commonly altered pathways in renal cell carcinoma, and that MAP3K13, CHAF1A, FDX1, ARHGAP26, ITGBL1, C10orf118, MTO1, LAMP2, STAMBP, DLC1, NSMAF, YY1, TPGS2, SCARB2, PRSS23, SYNJ1, CNPPD1, and PPP2R5E are the major sources of alteration for these pathways. The gene discussed is PRSS23; the disease is renal cell carcinoma.
