Figure 7. Correlation between risk genes expression and clinicopathological parameter of PRCC. (A) Boxplot showing that superior expression of UBE2C, DCB2, UBE2O, SIAH1, SKP2, and CDC20 were significantly related to advanced pathological grades, whereas low expression of CBLC and PRKN was significantly correlated with severe pathological features. (B) Boxplot showing that the expression of UBE2C, DCB2, SKP2, UBE2O, SIAH1, and CDC20 mRNA in PRCC samples are significantly correlated with severe pathologic staging and the expression of CBLC and PRKN at mRNA level were lower in patients with stage 4. *P < 0.05, **P < 0.01, ***P < 0.001, Abbreviations: ns: non-significance.
