目的:探讨鹰嘴豆芽素A对宫颈癌细胞增殖及迁移能力的调控作用及其可能的分子机制。方法:体外培养Hela细胞,以不同质量浓度的鹰嘴豆芽素A处理宫颈癌Hela细胞,CCK-8法检测鹰嘴豆芽素A对宫颈癌细胞的增殖影响;划痕实验检测对细胞迁移的影响;RT-PCR法检测鹰嘴豆芽素A对Bcl-2 /Bax mRNA水平表达的变化。结果:鹰嘴豆芽素A能够抑制Hela细胞的增殖和迁移,呈现剂量和时间依赖性(P<0.05);质量浓度为10、20、40、80、160 μmol/L鹰嘴豆芽素A处理Hela细胞24 h、48 h后,抑制Hela细胞增殖和迁移速率明显上升,并且高于对照组(P<0.05);促凋亡蛋白Bax表达水平升高,抗凋亡蛋白Bcl-2表达水平降低,呈剂量依赖性。结论:鹰嘴豆芽素A能够抑制宫颈癌Hela细胞的增殖和迁移,其作用机制可能与下调Bcl-2,上调Bax有关。

[Abstract]
Objective: The study is to investigate the regulation of Biochanin A on proliferation and migration of cervical cancer cells and its possible molecular mechanism. Methods: Hela cells were cultured in vitro and treated with different concentrations of Biochanin A. CCK-8 assay was used to detect the effect of Biochanin A on the proliferation of cervical cancer cells, while the Scratch assay was used to detect the effect on cell migration. Besides, the expression of Bcl-2 /Bax mRNA was detected by RT-PCR. Results: Biochanin A could inhibit the proliferation and migration of Hela cells in a dose-dependent and time-dependent manner. At 10,0,40,0,160 μmol/L of Biochanin A, the inhibition rate of Hela cells increased significantly after 24,8 h, significantly higher than that of the control group. The expression of pro-apoptotic protein Bax increased, while the expression of anti-apoptotic protein Bcl-2 decreased in a dose-dependent manner. Conclusion: Hummus A can inhibit the proliferation and migration of Hela cells in cervical cancer, and its mechanism may be related to the down-regulation of Bcl-2 and up-regulation of Bax.
