Silencing of N-cadherin in mouse mammary carcinoma cells led to decreased VE-cadherin expression and induced changes indicative of mesenchymal-epithelial transition, as indicated by re-induction of E-cadherin, localization of β-catenin at the cell membrane, decreased expression of vimentin and SIP1, and gain of epithelial morphology. The gene discussed is CDH1; the disease is breast carcinoma.
