Inhibition of Cell Growth of Human Ovarian Cancer by Xiaoaiping Injection via Akt Signal Pathway

目的研究消癌平注射液对卵巢癌细胞株Caov-3增殖作用的影响,以探讨其抗癌机制。方法 MMT法检测消癌平注射液对Caov-3细胞增殖活性的影响;相差显微镜观察细胞形态变化;流式细胞术分析消癌平注射液对Caov-3细胞周期的影响;免疫印迹方法检测消癌平注射液对Caov-3细胞质中Akt、pAkt、p27蛋白表达的影响。结果消癌平注射液能以时间和剂量依赖方式抑制Caov-3细胞增殖,并诱导Caov-3细胞发生G0/G1期阻滞;随着消癌平注射液作用时间的延长,Caov-3细胞质中pAkt蛋白表达减少,p27蛋白表达增加。结论消癌平注射液通过抑制PI3K/Akt通路,使细胞周期发生阻滞,从而抑制细胞增殖。

Objective To study the effect of Xiaoaiping injection on Caov-3 human ovarian cancer cells and its mechanisms. Methods After treatment with Xiaoaiping injection, viability of Caov-3 cells determined by MTT method. Phase contrast microscopy was used to observed the morphological changes of Caov-3 cells. Cell cycle was assessed by FACS. Cell signaling pathway protein-Akt and pAkt, and cell cycle associated protein-p27 were measured by western blot. Results Xiaoaiping injection inhibited the growth of Caov-3 human ovarian cancer cells in a dose and time dependent manner. Xiaoaiping injection induced G0/G1 phase arrest of Caov-3 cells, accompanied by pAkt down-regulation and p27 up-regulation. Conclusion Xiaoaiping injection can inhibit the proliferation of Caov-3 human ovarian cancer cells by inhibiting PI3K/Akt signaling pathway.
