Patients with esophageal squamous cell cancer are often diagnosed with advanced
diseases that respond poorly to chemotherapy. Overexpression of eIF4E leads to
enhance the translation of key malignancy-related proteins and enabling tumor
growth and chemoresistance in a variety of human malignancies, but whether it has
a role in ESCC remains obscure. We hypothesized that eIF4E promoted ESCC
tumorigenesis and facilitated the development of acquired resistance to the
cisplatin-based chemotherapy. In this study, we showed that eIF4E expression was
increased significantly in clinical ESCC tissues and and ESCC cell lines and its
expression level was correlated with lymph node metastasis, TNM stage, as well as
overall and disease-free survival of ESCC. We also showed here that knockdown of
eIF4E in EC9706 would dramatically reduced cell proliferation, colony formation,
migration and invasion, apoptosis in vitro as well as in vivo, and vice versa.
Moreover, "weak mRNAs" were demonstrated to be regulated by eIF4E in ESCC, which
might interpret the above function. Overexpression of eIF4E decreased the
efficacy of cisplatin-induced cell growth inhibition in ESCC cell line and
xenograft model (P < 0.05). eIF4E knockdown by shRNA increased cisplatin-induced
cytotoxicity in ESCC cell lines, and enhanced chemosensitivity to cisplatin in
xenograft tumor models. Furthermore, we found that the PI3K/AKT pathway and
Bcl-2/Bax ratio might be responsible for the eIF4E-induced cisplatin resistance
in ESCC. Our data collectively show association of eIF4E expression with
chemotherapeutic response in ESCC, and suggest that therapeutically targeting
eIF4E may be a viable means of improving chemotherapy response in ESCC.
