Migrating tumor cells lose the expression of the epithelial marker E-cadherin, a protein involved in the extensive cell adhesions to neighboring cells and the basement membrane and acquire mesenchymal markers, such as N-cadherin and vimentin, a protein overexpressed in most epithelial cancers, whose levels are correlated with tumor migration, invasion, and poor prognosis [9,10]. This evidence concerns the gene CDH1 and neoplasm.
