[Effects of component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on cell proliferation, apoptosis and skeleton in lung cancer A549 cells].

This study aims to optimize the most effective component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on lung cancer A549 using the orthogonal design method,and to investigate its effects of the component formula on cell proliferation,apoptosis and cytoskeleton in lung cancer A549 cells. The orthogonal design method was introduced to optimize the most effective component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on lung cancer A549 cells. CCK-8 assay and Real-time cell analysis were adapted to analyze the effect of component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on A549 cells viability at different time and dose. Cell apoptosis was measured by Annexin VFITC / PI double staining and flow cytometry. Cell skeleton protein F-actin was detected by high content screening( HCS). The optimizing component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma for total salvianolic acid,total saponins of panax ginseng and ginseng polysaccharide doses were 5,10,5 mg·L-1. CCK-8 assay and Real-time cell analysis demonstrated that the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma treatment could significantly decrease the A549 cell viability in both dose-and time-dependent manner compared with control group( P 0. 01). Moreover,the increase of cell apoptosis was detected by Annexin V-FITC / PI double staining and flow cytometry when cells treated with the component formula,which indicating that the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma could induce A549 cell apoptosis in a time-dependent manner compared with control group( P 0. 01). Furthermore,compared with control group,a significant decrease in A549 cell skeleton area was found in the component formula-exposed cells in the dose-dependent manner( P 0. 01). In summary,the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma inhibits A549 cell proliferation by inducing cell apoptosis and decreasing cell microfilament formation. All of these results will be helpful to reveal antitumor mechanism of the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma,which provides a basis for the exploration of antitumor mechanism of the component formula on lung cancer.
