Although not all the EMT markers were similarly altered, partial EMT was confirmed in each cancer cell type, with an increase in several mesenchymal traits including N-cadherin (CDH2), Snail (SNAIL1), Slug (SNAIL2), ZEB1 and vimentin, and/or a reduction in ZO-1 and E-cadherin (CDH1) as documented by mRNA quantification (Fig. 5b and Supplementary Fig. 5a, b) and protein immunodetection (Fig. 5c and Supplementary Fig. 5c, d). This evidence concerns the gene SNAI2 and cancer.
