To explicit whether PTPRG overexpression activated the oxidative phosphorylation of ccRCC cells, we detected the protein levels of ATP5A1, MTCOX2, ND1, SDHB, and UQCRC2, and we observed the increased expression of ND1, SDHB, ATP5A1, and especially MTCOX2 protein significantly (Figure 7(b)). The gene discussed is SDHB; the disease is nonpapillary renal cell carcinoma.
