研究消癌解毒方抗乳腺癌细胞的活性及作用机制。方法 显微镜观察MDA-MB-231细胞形态,MTT法考察细胞的增殖抑制率,流式细胞术观察细胞周期,Western blot检测PI3K/AKT信号通路相关蛋白P53、P21、Cyclin B1、CDK1的表达。结果 与对照组相比,消癌解毒方给药组细胞减少,排列疏松,体积变小,形态变圆;消癌解毒方可以提高MDA-MB-231细胞的增殖抑制率(P<0.05~0.01),使肿瘤细胞的细胞周期阻滞于G2/M期(P<0.05~0.01),可以抑制与细胞周期相关的PI3K/AKT信号通路,上调P53、P21,下调Cyclin B1、CDK1蛋白的表达(P<0.05~0.01)。结论 消癌解毒方能阻滞MDA-MB-231细胞周期,抑制乳腺癌细胞的增殖,其机制可能与抑制PI3K/AKT信号通路有关。 |

OBJECTIVE To study the anti-proliferative activity and mechanism of Xiao'ai Jiedu decoction against breast cancer cell lines MDA-MB-231. METHODS The cell morphology was observed by microscope. MTT method was used to investigate the inhibitory rate of Xiao'ai Jiedu decoction against breast cancer cell lines MDA-MB-231. Flow cytometry analyzed the cell cycle distribution. Western blot detected the expression of Cyclin B1 and CDK1 and the expression of upstream signaling molecules P53, P21 in PI3K/AKT signaling pathway. RESULTS Compared with the control group, MDA-MB-231 cells of Xiao'ai Jiedu decoction group showed number-decreased, loosely arranged, morphology-smaller and rounder. Xiao'ai Jiedu decoction inhibited the proliferation of MDA-MB-231 cells(P<0.05, P<0.01). Xiao'ai Jiedu decoction down-regulated the expression of Cyclin B1 and CDK1, inhibited the PI3K/AKT signaling pathway, and up-regulated the expression of P53 and P21(P<0.05, P<0.01). CONCLUSION Xiao'ai Jiedu decoction can inhibit the proliferation of MDA-MB-231 breast cancer cells, perhaps related to inhibiting the PI3K/AKT signaling pathway. |
