Although vimentin was expressed in three of the six ALK-rearranged NSCLC cell lines tested, these cell lines were categorized as either having a mesenchymal-like phenotype (low E-cadherin and high vimentin levels) or an epithelial-like phenotype (high E-cadherin and low vimentin levels; Fig. 4a). The gene discussed is VIM; the disease is non-small cell lung carcinoma.
