ZEB1 expression is a hallmark of claudin-low breast tumors (Morel et al., 2012; Fougner et al., 2019; Stemmler et al., 2019; Pommier et al., 2020) and ZEB1 counteracts the onset of oxidative stress in response to oncogene-induced replicative insults (Morel et al., 2017). Here, ZEB1 is linked to breast neoplasm.
