丹参-人参组分配伍对肺癌A549增殖、凋亡和骨架的影响

中药组分配伍抗肿瘤研究是近年来治疗恶性肿瘤的新方向。该研究通过正交设计优选丹参-人参活性组分抗肺癌A549的有效配伍,并探讨其对肺癌A549细胞增殖、凋亡和骨架的影响。研究发现,正交设计优选出丹参-人参组分配伍抗肺癌的最佳组合为丹参总酚酸、人参总皂苷和人参多糖的最佳配伍剂量为5,10,5 mg·L-1。并利用CCK-8法结合实时细胞分析技术检测丹参-人参组分配伍对肺癌细胞增殖的量效和时效关系,结果显示丹参-人参组分配伍能以时间和剂量依赖性的方式显著抑制肺癌A549细胞的增殖。进一步采用流式细胞术分析丹参-人参组分配伍对肺癌细胞凋亡的影响和高内涵细胞成像系统分析丹参-人参组分配伍对肺癌细胞骨架蛋白F-actin表达的影响,结果显示丹参-人参组分配伍能够显著诱导肺癌A549细胞凋亡和显著降低肺癌A549细胞骨架的面积,且呈一定的剂量依赖性。综上表明丹参-人参组分配伍能抑制肺癌A549细胞的增殖和生长,具有治疗肺癌的应用前景,其机制与诱导肿瘤细胞凋亡及减少微丝形成相关。

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 V-FITC/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.
