ZEB1 and nonpapillary renal cell carcinoma: Similarly, luciferase activity of ccRCC cells cotransfected with wild‐type ZEB1 3′‐UTR reporter vector (ZEB1‐wt) and miR‐205‐5p mimic was markedly impaired, but cotransfection with miR‐205‐5p inhibitor obviously increased luciferase activity in ccRCC cells.
