EMT occurs gradually through several cellular states expressing different levels of epithelial and mesenchymal markers and exhibiting features intermediate to those of epithelial and mesenchymal cells.46, 47, 48 Although EMT may require many factors other than DUSP6, DUSP6 was required for fibronectin and N‐cadherin expression and for partially inducing EMT in endometrial cancer cells. This evidence concerns the gene FN1 and endometrial cancer.
