In the TCGA melanoma dataset, the top 312 genes with a positive correlation (down to Spearman r = 0.5) with the prototypic EMT marker ZEB1, were also positively correlated with SNAI1, NFATc2, CDH2, and AXL, but negatively with MITF and CDH1 (Supplementary Table S1). Here, AXL is linked to melanoma.
