As expected from previous data in melan‐a and B16F10 murine cells (Caramel et al, 2013; Dou et al, 2014), ZEB1 knockdown in A375 cells prevented tumor initiation in nude mice (Fig 6E), clearly demonstrating that ZEB1 is required for the tumorigenic capacity of melanoma cells. Here, ZEB1 is linked to melanoma.
