These data were further underlined by the survival of RCC patients according to Kaplan–Meier curves [55], which showed a significantly lower overall survival in ccRCC patients with low levels of TGFBR2 in comparison to the ones with high expression of TGFBR2 (Supplementary Figure 4). The gene discussed is TGFBR2; the disease is nonpapillary renal cell carcinoma.
