摘要
目的:探讨美洲大蠊提取物(CⅡ-3)对两株人肺癌细胞(NCI-H446、NCI-H460)的细胞毒活性及细胞周期的影响。方法:采用改良MTT法检测了CⅡ-3对NCI-H446和NCI-H460人肺癌细胞的细胞毒活性,流式细胞术检测CⅡ-3对2株细胞凋亡、坏死率及细胞周期的的影响。结果:CⅡ-3对NCI-H446和NCI-H460细胞的IC50分别为(48.98±6.63)μg.mL-1、(33.00±10.57)μg.mL-1。对NCI-H446和NCI-H460细胞凋亡、坏死率的影响具有一定的剂量依赖性。对NCI-H446细胞,25,50μg.mL-1CⅡ-3诱导细胞的不同时期发生阻滞,75μg.mL-1CⅡ-3主要诱导细胞发生坏死;对NCI-H460细胞,20,80μg.mL-1CⅡ-3主要诱导细胞S期、G2/M期发生阻滞,40μg.mL-1CⅡ-3主要诱导细胞S期发生阻滞。结论:美洲大蠊提取物CⅡ-3对2株人肺癌细胞有一定的细胞毒活性,且对2株细胞的凋亡、坏死率和细胞周期分布有一定的影响。
Objective:To investigate the cytotoxicity and effect of cell cycle of Perplaneta americana extract(CⅡ-3) on two human lung tumor cell lines.Methods:The cytotoxicity of CⅡ-3 assessed with modified MTT assaying,and the apoptotic,necrotic rate and distibution of cell cycle were analysed by flow cytometry.Results:The IC50 values of CⅡ-3 on NCI-H446 and NCI-H460 were(48.98±6.63) μg·mL-1 and(33.00±10.57) μg·mL-1.The apoptotic,necrotic rate of two cell lines,there existed some dose-dependment manners.For NCI-H446,25,50 μg·mL-1 CⅡ-3 induced cell cycle arrests and 75 μg·mL-1 induced necrosis;For NCI-H460,20,80 μg·mL-1 CⅡ-3 induced S,G2/M arrests,and 40 μg·mL-1 induced S arrest.Conclusion:Periplaneta americana extract(CⅡ-3) exists some cytotoxicity,and affect the apoptosis,necrosis and distrbution of cell cycle of NCI-H446,NCI-H460.
