Overexpression of Twist2 induced the EMT phenotype including downregulation of E-cadherin, and upregulation of N-cadherin and β-catenin in human ovarian cancer cells, suggesting that Twist2 might promote β-catenin release from the E-cadherin/β-catenin complex through inhibition of E-cadherin. This evidence concerns the gene CDH1 and ovarian cancer.
