紫甘蓝提取液对人乳腺癌细胞生长和迁移的抑制作用

目的:探讨紫甘蓝提取物对乳腺癌细胞MCF7生长和迁移的抑制作用。方法:应用MTT法检测不同浓度紫甘蓝提取物对MCF7增殖的抑制作用,并用倒置相差显微镜观察细胞形态,Annexin V-FITC/PI染色细胞后用流式细胞术检测不同浓度紫甘蓝提取物对MCF7凋亡的影响,采用Transwell法检测不同浓度紫甘蓝提取物对MCF7迁移的影响。采用SPSS16.0软件对实验结果进行统计学处理。结果:紫甘蓝提取物可抑制MCF7的增殖,并呈浓度依赖性和时间依赖性(P0.05),也使MCF7形态发生了异常变化,紫甘蓝提取物可诱导MCF7凋亡、抑制其迁移,且呈浓度-效应关系(P0.05)。结论:紫甘蓝提取物可抑制乳腺癌细胞MCF7生长和迁移。

Purple Cabbage Extract in Inhibition of Breast Cancer Cell Growth and Migration

To investigate the effect of purple cabbage extract (PCE) on breast cancer cell MCF7 growth and migration.Methods:The inhibition rate of MCF7 cells was assessed by MTT method,and the inverted phase contrast microscope was used to observe the cellular shape.Flow cytometry was utilized for measuring cell apoptosis after Annexin V-FITC/PI stained the cell.The transwell chamber was used to investigate cell migration.Results:PCE inhibited MCF7 cell proliferation in a concentration-and time-dependent manner (P<0.05).After incubated with PCE,the cells became shrinkage and turned round,arranged loosely and adhered not favorable gradually.PCE induced MCF7 cell apoptosis and inhibited cell migration in a concentration-dependent manner (P<0.05).Conclusion:PCE inhibits breast cancer cell MCF7 growth and migration.
