During the acquisition of EMT characteristics, cancer cells lose the expression of genes that promote cell-cell contact, such as E-cadherin and the miR-200 family, and gain the expression of mesenchymal markers, such as vimentin, fibronectin, and N-cadherin, leading to enhanced cancer cell migration and invasion [6]–[8] and to confer drug resistance characteristics on cancer cells [9]. This evidence concerns the gene FN1 and cancer.
