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)). Here, ATP5F1A is linked to nonpapillary renal cell carcinoma.
