Effects of Xiaoxianxiong Tang on biological behavior in lung cancer cell line A549

Obiective:To investigate the effects of Xiaoxianxiong Tang on the proliferation,invasion,apoptosis,and other cell biological behaviors of non-small cell lung cancer A549 cells.Methods:Human lung adenocarcinoma A549 cells were cultured in vitro,and the IC50 concentration and effective time of administration of Xiaoxianxiong Tang were determined by the CCK-8 assay to detect the inhibitory effect of Xiaoxianxiong Tang on A549 cells proliferation.The effect of the Xiaoxianxiong Tang on apoptosis was determined by flow cytometry;the apoptosis-related protein was detected via Western blot;the metastasis-related protein mRNA was detected by RT-PCR.Results:Xiaoxianxiong Tang significantly inhibited the proliferation viability,the invasive ability,and the clonogenic ability of A549 cells compared with the control group(P<0.001).Moreover,Xiaoxianxiong Tang significantly promoted the apoptosis of A549 cells(P<0.001).Xiaoxianxiong Tang significantly up-regulated Bax and down-regulated Bcl2 expression in A549 cells compared with the control group(P<0.01).The mRNA expression of MMP2 and MMP9 was significantly down-regulated by Xiaoxianxiong Tang compared with the control group(P<0.05).Conclusion:Xiaoxianxiong Tang has the effect of regulating the biological behavior of A549 cells,and Xiaoxianxiong Tang significantly inhibites the proliferation viability,colony formation,and invasion ability of lung cancer A549 cells.
