In addition to Ndufa4l2, we performed immunoblotting of α-Enolase 1 (Eno1), a prognostic marker in clear cell renal cell carcinoma (29), and glucose-6-phosphate isomerase (Gpi1), independent adverse prognostic markers of ccRCC aggressiveness and progression-free survival (30). This evidence concerns the gene PIGQ and nonpapillary renal cell carcinoma.
