Additionally, MAPK14 knockdown inhibits the proliferation and migration of ccRCC cells, an effect that is partially reversed by CDC25B overexpression, suggesting that downregulation of MAPK14 and P‐MAPK14 inhibits the proliferation and migration of ccRCC by downregulating CDC25B. The gene discussed is MAPK14; the disease is nonpapillary renal cell carcinoma.
