CDH2 and neoplasm: Key steps in tumor-associated EMT are down-regulation of E-cadherin by transcriptional repressors such as Snail1, ZEB1, and Twist, and induction of mesenchymal-specific gene expression, such as Vimentin, Fibronectin, and N-cadherin, which leads to the conversion of stationary epithelial cells into migratory mesenchymal cells[11, 12].
