BackgroundHepatocellular carcinoma (HCC) is the third-leading cause of cancer-related mortality with poor prognosis and treatment. More effective strategies should be studied in HCC.MethodsAfter treated with ruscogenin, the cell proliferation was assessed by CCK-8 method. Cell migration and invasion were estimated using wound healing and transwell assays. Pathological changes of lung tissue were observed by HE staining and IHC methods. MMP-2, MMP-9, uPA, VEGF and HIF-1α levels were measured using ELISA, RT-qPCR and WB tests. PI3K/Akt/mTOR pathway related molecules were detected using WB analysis.ResultsThe results indicated the hypotoxicity of ruscogenin. Meanwhile, ruscogenin showed obvious interruption on the cancer cell migration and invasion, and inhibition on the metastatic foci in pulmonary tissue. Significantly, ruscogenin decreased the levels of MMP-2, MMP-9, uPA, VEGF and HIF-1α, down-regulated the phosphorylation of Akt, mTOR.ConclusionThe present study indicated a novel use of ruscogenin in suppressing HCC metastasis by reducing the expression of MMP-2, MMP-9, uPA, VEGF and HIF-1α via regulating the PI3K/Akt/mTOR signaling pathway.
