摘要: 目的 探讨TSA对人肺癌细胞系A549的作用及其对上皮间质转化(EMT)的调控机制。方法 用MTT实验分析TSA体外抑制A549细胞的增殖能力;用划痕实验检测细胞的迁移;用Western blot法检测EMT相关marker蛋白的表达。结果 TSA对A549细胞的增殖具有明显的抑制作用(p<0.01),TSA通过EMT途径抑制A549细胞的侵袭与迁移。结论 TSA可体外抑制A549细胞,其部分机制是通过抑制EMT途径实现的。

Abstract: Objective To investigate the effect of TSA on lung cancer cell A549 and its possible mechanism. Methods Proliferation ability of A549 cells was detected by MTT assay; Migration of A549 cells was measured by Wound healing assay; The expression EMT markers proteins level were detected by Western blot. Results TSA significantly inhibited the proliferation of A549 cells(p<0.01). TSA inhibited A549 cells invasion and migration via inhibition of EMT. Conclusion TSA may effectively inhibit the ability of proliferation and migration of lung cancer, and the mechnism may be explained by inhibition of EMT.
