The process of EMT involves cancer cells losing their epithelial characteristics, including cell adhesion, cell tight junctions, strong cytoskeleton structures, and E-cadherin (CDH1) and β-catenin (CTNNB1) expression levels followed by an increase in mesenchymal characteristics (fibroblast-like shape, upregulation of fibronectin (FN) and N-cadherin (CDH2)) [7]. This evidence concerns the gene FN1 and cancer.
