ZEB1 and carcinoma: Of note, while the ectopic expression of ZEB1/ZEB2 has been associated with attenuated cell proliferation in carcinoma models (Mejlvang et al, 2007), we did not observe any proliferation defect upon ZEB1 expression in melanoma cells, further highlighting cell‐type‐specific functions of ZEB1 and ZEB2 in melanoma compared to carcinoma, as we previously reported (Caramel et al, 2013; Puisieux et al, 2014).
