OBJECTIVE:To study the inhibitory mechanism of timosaponin B-Ⅱ(TB-Ⅱ) on the proliferation and migration of human lung cancer A549 cells. METHODS:A549 cells were treated with TB-Ⅱ [0(blank control),1,10 and 100 μg/ml] for 48 h,and total RNA and total protein were extracted respectively. Real time fluorescence quantitative-PCR and Western blot were used to detect mRNA and protein levels of IL-18. IL-18 in A549 cells was silenced by transfection;the expression of IL-18 mRNA and protein were compared among untransfection group,negative control group and transfection group;and then human lung can-cer A549 cells with silenced gene were treated with 10 μg/ml TB-Ⅱ for 24,48 and 72 h. The activity of cell proliferation was de-tected with CCK-8,and the change of cell migration ability was observed by streak method. RESULTS:Compared with blank con-trol,the expression of IL-18 mRNA and protein in A549 cells all increased after treated with TB-Ⅱ(P<0.05 or P<0.01),and were positively correlated with concentration. Compared with untransfection group,the expression of IL-18 mRNA and protein de-creased in transfection group(P<0.01). Compared with untransfected cell treated with TB-Ⅱ,the viability and migration ability of A549 cells with transfection gene increased after treated with TB-Ⅱ for 72 h(P<0.01). CONCLUSIONS:TB-Ⅱ can inhibit the proliferation and migration of A549 cells by up-regulating IL-18 gene expression.
