VIM and cancer: Epithelial‐mesenchymal transition (EMT) is one of the most widely studied mechanisms not only in GC9 but also in pancreatic cancer,10 breast cancer,11 and lung cancer.12 EMT is a reversible process in which epithelial cells lose polarity and cell‐cell adhesion characteristics and acquire mesenchymal cell characteristics.13 EMT‐expressing cancer cells showed decreased expression of epithelial cell markers such as E‐cadherin and ZO‐1, while expression of mesenchymal cell markers such as vimentin and N‐cadherin increased.
