Furthermore, cell growth, colony formation, migration ability and the epithelial-mesenchymal transition markers of ESCC cells in which TACC3 were knocked-down were measured. The mRNA and protein levels of TACC3 were higher in ESCC specimens compared to non-tumorous esophageal epithelial tissues. IHC results revealed TACC3 expression was significantly correlated to differentiation ( p = 0.017) and lymphoid nodal status ( p = 0.028). The patients with high-expression of TACC3 had a significantly poor prognosis compared to those of low-expression ( p = 0.017), especially in the patients at stages I–II ( p = 0.028). Multivariate analysis indicated that TACC3 expression was an independent prognostic factor for ESCC patients ( p = 0.025). Knockdown of TACC3 inhibited the ability of cell proliferation, colony formation and migration. This study first identifies TACC3 not only as a useful biomarker for diagnose and prognosis of ESCC, but also as a potential therapeutic target for patients with ESCC.
