The relative expression of miR-335-5p was significantly downregulated in the ccRCC group compared with the normal group (Figure 5(c)), and miR-335-5p expression was negatively correlated with the CCRK expression, which indicated that miR-335-5p could be a negative predictive factor in ccRCC. The gene discussed is CDK20; the disease is nonpapillary renal cell carcinoma.
