Figure 5. Expression, alteration frequency, and prognosis of the 10 risk genes. (A) Validation of the mRNA expression levels of the ten risk genes in PRCC tissues and normal renal tissues. (B) Validate signature genes by the blast with independent cases via the cBioportal database. (C) Association between gene expression and overall survival in PRCC evaluated using the Kaplan-Meier plotter database. Probe number, hazard ratio (HR), and log-rank P values are shown in each panel. *P < 0.05, **P < 0.01, ***P < 0.001.
