ZEB1 and non-small cell lung carcinoma: Paralleling our findings in NSCLC cell lines (Figure 2f), EMT-TFs and Vimentin were differentially expressed in these cells, for example, SNAI1, ZEB1/2 and Vimentin were expressed at low levels in BE088T but highly abundant in others (BE060T, BE069T, BE079T, BE084T and BE090T), stratifying the cells into two categories: one with basal EMT signaling and the other with an more activated EMT, indicative of more mesenchymal-like subpopulations within the cells (Figure 4b; Supplementary Table S3).
