Effects of Artesunate and Its Mechanism on MCF-7 Cells

    摘要
  • 摘要: 目的探讨青蒿琥酯(Artesunate,ART)对乳腺癌细胞MCF-7抑制作用及其机制。方法ART处理细胞3天后,采用MTT比色法检测细胞增殖功能,观察细胞形态、结构的改变,免疫细胞化学检测bax、nm23、PCNA、VEGF、bcl-2蛋白的表达情况。结果ART对乳腺癌细胞MCF-7的抑制作用呈明显浓度依赖性,可导致细胞形态、结构的改变;免疫细胞化学结果显示20μmol/L青蒿琥酯作用两种细胞72小时后,可上调bax、nm23,下调PCNA、VEGF蛋白的表达,bcl-2蛋白表达无明显变化。结论ART有抑制MCF-7细胞增殖的作用,其机制可能与上调bax、nm23,下调PCNA、VEGF蛋白的表达有关。

     

    Abstract: Objective To study the effects of artesunate(ART)and its mechanism on MCF-7 cells. Methods After treated MCF-7 cells with ART for 3 days,the proliferation of MCF-7 cells were examined with MTT-assay,meanwhile the morphological change and the expression of PCNA,bcl-2,bax and nm23 was observed. Results MCF-7 cells were treated with ART for 3d,led to a obviously dose dependent inhibition.ART could change the morphology and ultra structure of MCF-7 cells significantly.Immunocytochemical staining indicated treatme...
