Moreover, compared with patients in the low-risk group, ccRCC patients in the high-risk group exhibited higher expression of RPIA, G6PD, PSAT1, ENO2, HK3, and IDH1 and lower expression of PDK4, PGM2, PGK1, FBP1, OGDH, SUCLA2, and SUCLG2 (Figures 7(c) and 7(h)). Here, OGDH is linked to nonpapillary renal cell carcinoma.
