We developed an EMT classifier based on the fold change of epithelial markers CDH1 (encoding E-cadherin) and JUP (encoding plakoglobin), and mesenchymal markers including SNAI1 (encoding snail homolog 1), TWIST1 (encoding twist-related protein1), CDH2 (encoding N-cadherin), ZEB1 (encoding zinc-finger E-box binding homeobox 1), and VIM (encoding Vimentin), allowing us to classify tumor samples as “Epithelial” or “Mesenchymal” according to their EMT score (see Methods). This evidence concerns the gene SNAI1 and neoplasm.
