H1299 lung adenocarcinoma cells exhibit a mesenchymal phenotype, marked by high vimentin expression levels and no E-cadherin expression, and these cells migrate as individual cells; in contrast, H1975 lung adenocarcinoma cells express both vimentin and E-cadherin, indicating an E/M phenotype, and these cells migrate collectively [38]. Here, VIM is linked to lung adenocarcinoma.
