ZEB1 expression was found to be significantly elevated in cancer tissues compared with normal counterparts (P < 0.05, Figure 1(a)), and ZEB1 was obviously up-regulated in CC cell strains (HeLa, Caski, C-33A, and AV3) compared with HUCEC (P < 0.05, Figure 1(b)), suggesting the involvement of ZEB1 in the onset and development of CC. Here, ZEB1 is linked to cancer.
