Results exhibited that the protein levels of ENO2, PFKP, PLIN2, TRIB3, RIMKLA, PLOD2, GMPPA, and HYI were higher in ccRCC, while the protein levels of METAP1 and GALNT7 were lower and the protein level ITPKB remained the same, in comparison with normal kidney tissues (Fig. 11C). Here, GMPPA is linked to nonpapillary renal cell carcinoma.
