The correlation between high ZEB1 and low MITF expression was confirmed in a collection of 467 primary and metastatic melanomas from The Cancer Genome Atlas (TCGA; Cerami et al, 2012; Gao et al, 2013; The Cancer Genome Atlas Network, 2015) (P < 2.2E‐16; Fig 2A). The gene discussed is ZEB1; the disease is metastatic melanoma.
