The 14-gene EMT classifier was used in our previous study [19] to define the EMT states of NSCLC tumors, including three mesenchymal markers (ZEB1, VIM, and FN1) and 11 epithelial markers (CDH1, EPCAM, ESRP1, ESRP2, DDR1, CTNNB1, CD24, CLDN7, KRT8, KRT19, and RAB25). This evidence concerns the gene CLDN7 and non-small cell lung carcinoma.
