Expression and function of tetraspanin 1 in esophageal carcinoma.

ABSTRACT: The present study explored the expression of tetraspanin 1 (TSPAN1) in esophageal carcinoma (EC) and its association with clinicopathological factors. TSPAN1 small interfering RNA (siRNA) was designed to target the TSPAN1 gene in Eca-109 cells in order to explore the biological function of TSPAN1 in the proliferation and apoptosis of EC. The results demonstrated that the level of TSPAN1 expression in EC tissue was significantly increased compared with that in adjacent normal tissue (P<0.001). TSPAN1 expression was also associated with histological differentiation, depth of invasion, lymph node metastasis (all P<0.05) and Ki-67 (P<0.01). However, no association was observed between TSPAN expression and gender, age or location (P>0.05). In addition, silencing TSPAN1 markedly inhibited prolif
