OBJECTIVES: To investigate the mechanism of astragaloside IV (AS-IV) inhibiting the invasion and metastasis of vulvar squamous cell carcinoma (VSCC).
MATERIAL AND METHODS: MTT and plate colony-formation assays were used to examine the cell proliferation of VSCC (SW962 cell line). Transwell and scratch wound-healing assays were used to analyse cell migration and invasion. Western blot was used to detect the expression of relevant proteins in terms of cell proliferation, invasion and metastasis, as well as the TGF-β1/FAK/AKT signaling pathway.
RESULTS: The results showed that AS-IV inhibited the proliferation of SW962 cells in a concentration-dependent manner, as demonstrated by the upregulation of P53 and P21 expression and the downregulation of cyclin D1 expression. AS-IV decreased the ability of cell invasion and metastasis by the downregulation of MMP-2 and MMP-9 expression. When TGF-β1 was added to SW962 cells, the expression of the N-cadherin and Vimentin were upregulated and that of the E-cadherin was downregulated. Subsequently, fibroblast-like elongated spindle-shaped cells appeared, which suggests that TGF-β1 could induce EMT in SW962 cells. Furthermore, the expression of p-FAK, p-AKT, MMP-2 and MMP-9 were upregulated. The expression of these proteins exhibited the opposite effect after AS-IV intervention. Cell invasion and metastasis were suppressed.
CONCLUSIONS: AS-IV inhibits cell invasion and metastasis in VSCC through the TGF-β1/FAK/AKT signalling pathway.
