Abstract Background Fascin induces membrane protrusions and cell motility. Fascin overexpression was associated with poor prognosis, and its downregulation reduces cell motility and invasiveness in esophageal squamous cell carcinoma (ESCC). Using a stable knockdown cell line, we revealed the effect of fascin on cell growth, cell adhesion and tumor formation. Methods We examined whether fascin is a potential target in ESCC using in vitro and in vivo studies utilizing a specific siRNA. We established a stable transfectant with downregulated fascin from KYSE170 cell line. Results The fascin downregulated cell lines showed a slower growth pattern by 40.3% (p In vivo, the tumor size was significantly smaller in the tumor with fascin knockdown cells than in mock cells by 95% at 30 days after inoculation. Conclusions These findings suggest that fascin overexpression plays a role in tumor growth and progression in ESCC and that cell death caused by its downregulation might be induced by cell adhesion loss. This indicates that targeting fascin pathway could be a novel therapeutic strategy for the human ESCC.
