VIM and hypopharynx cancer: Because the possible involvement of γSMA was hypothesized in the context of epithelial-mesenchymal transition (Benzoubir et al. 2015), we tested the expression of both α/γSMA in cells of the FaDu line from hypopharyngeal cancer wounded by the scratch test, where we compared the expression of both proteins with mesenchymal marker vimentin (Vim).
