VIM and breast carcinoma: However, although these cadherins are unable to completely reverse the mesenchymal phenotype in invasive breast cancer cells (as evidenced by the maintenance of multiple actin stress fibers, focal adhesions, and the expression of vimentin [[29,30] and current work]), we show here that either E- or P-cadherin reduces the ability of 231 cells to infiltrate as single cells, by promoting an epithelial-like collective cell migration.
