we applied the univariate Cox regression analysis with p < 0.05 to select the prognostic‐related genes, and the results reveal that the expression of HDAC7, HDAC8, and HDAC10 are positively correlated with survival rates and the expression of HDAC5, HDAC11 are negatively correlated with survival rates in ccRCC patients (Figure 3A). The gene discussed is HDAC8; the disease is nonpapillary renal cell carcinoma.
