Data from CPTAC showed that PPP2CA protein expression was higher in renal cancer tissues than in adjacent non-cancerous renal tissues (Fig. 3E), corroborating our experimental data showing significantly higher PPP2CA protein concentrations in ccRCC tissues (Fig. 3F-3G) and other renal cancer cell lines (Fig. 3H-3I) than in normal tissues. The gene discussed is PPP2CA; the disease is nonpapillary renal cell carcinoma.
