Abstract

Abstract: PURPOSE: To investigate the effects of salinomycin on proliferative, migratory and invasive properties of tongue squamous cell carcinoma cells, and to explore its possible mechanism. METHODS: CCK8 assay was used to detect the effect of salicamycin and cisplatin on proliferative abilities of CAL-27 cells and EA.hy926 cells. The invasive and migratory ability was detected by Transwell assay. The protein expressions of E-cadherin, vimentin and β-catenin was evaluated by Western blot. SPSS20.0 software package was used to analyze the data. RESULTS: Salicamycin can effectively inhibit proliferation of CAL-27 cells, and the inhibitive ability of salicamycin on the proliferation was stronger than that of cisplatin. CAL-27 cells were treated by salinomycin (4 μmol/L) before invasive and migratory abilities were examined. Compared with control group, the number of invasive and migratory cells in the salinomycin-treated group was significantly decreased (P<0.05). Western blot analysis showed that the protein expression of vimentin and β-catenin was significantly down-regulated. The expression of E-cadherin was significantly increased with the increase of salicamycin concentration. CONCLUSIONS: The proliferative, invasive and migratory ability of CAL-27 cells can be inhibited by salinomycin, which may be related to the inhibition of epithelial-mesenchymal transitions.
