RESUMEN

Aidi injection, a proprietary Chinese medicine, has been widely used for the treatment of cancer. However, its effects and potential mechanism in esophageal squamous cell carcinoma (ESCC) have not yet been characterized. The aim of the present study was to identify the mechanism underlying the anti­metastatic effects of treatment with Aidi. To test the effects and mechanism, EC9706 and KYSE70 cells were selected for in vitro experiments. In vivo, the anti­metastatic effects of Aidi injection on a nude mouse peritoneal metastasis model were examined, and the mechanisms were assessed with immunohistochemical staining. A cell proliferation assay demonstrated that treatment with more than 3 mg/ml Aidi for 24 or 48 h significantly inhibited the proliferation of EC9706 (P<0.01) and KYSE70 cells (P<0.05, P<0.01). Subsequent experiments assessed cell migration, invasion and vasculogenic mimicry (VM) formation, with 5­fluorouracil serving as a positive control. It was observed that treatment with Aidi inhibited cell migration, invasion and VM formation. Furthermore, it was identified that treatment with Aidi inhibited epithelial­mesenchymal transition (EMT) signaling and the expression of vascular endothelial growth factor A (VEGF­A) in EC9706 and KYSE70 cells, using western blotting. In the in vivo experiments, Aidi injection effectively suppressed tumor metastasis in the mouse tumor model. Additionally, the expression of vimentin and vascular endothelial growth factor was decreased, and the expression of cadherin­1 was increased in the tumor tissue. The present results suggested that treatment with Aidi may inhibit tumor metastasis in ESCC through the inhibition of EMT signaling and angiogenesis.
