ZEB2 and carcinoma: There is substantial evidence to indicate that the zinc-finger transcriptional factors Snail and Slug, the two-handed zinc factors ZEB1/dEF1 and ZEB2/SIP1, and the basic helix-loop-helix transcription factors Twist and E12/E47 play major roles in epithelial carcinoma plasticity [38–41], and tumor progression and invasiveness [42–45].
