The EMT is an important step in tumor migration and invasion, and it is characterized by the loss of the epithelial properties of cells, such as adhesion and the expression of the epithelial marker E-cadherin, and the acquisition of mesenchymal properties, such as increased cell motility and the up-regulation of the mesenchymal markers N-cadherin and vimentin [10]. The gene discussed is CDH1; the disease is neoplasm.
