The results displayed that the cell proliferation indexes were significantly decreased in the miR-335-5p mimic group compared with the miR-NC group, importantly, CCRK can reverse this inhibitory effect of miR-335-5p on ccRCC cell proliferation (Figures 6(a), 6(b), 6(e), and 6(f)). The gene discussed is CDK20; the disease is nonpapillary renal cell carcinoma.
