中文摘要:
      目的 探讨二烯丙基二硫(DADS)诱导人鼻咽癌CNEl细胞凋亡的生物学效应.方法 通过MTT法检测DADS对CNE1细胞生长的影响;用光学显微镜、流式细胞仪研究DADS诱导细胞凋亡的作用.免疫组织化学法检测细胞内Bcl-2、Bax蛋白的表达,Western blot法检测细胞内Caspase-3蛋白的表达.结果 DADS能抑制CNE1细胞的生长.DADS处理CNE1细胞后,细胞呈凋亡特征性改变.流式细胞分析显示DADS呈浓度依赖性诱导CNE1细胞凋亡.免疫组织化学结果表明DADS处理细胞后,Bax蛋白表达升高,Bcl-2蛋白表达下降.随药物浓度的增加Caspase-3蛋白表达增强.结论 DADS具有诱导CNE1细胞凋亡的作用,其机制可能与Bcl-2/Bax下降,促进Caspase-3活化有关.
英文摘要:
      Objective To study the effect of diallyl disulfide on CNE1. Methods The growth inhibition of CNE1 cells was measured by MTT.The effect of DADS on induction of apoptosis of CNE1 cells was studied by light microscopy and flow cytometry,respectively.Bcl-2,Bax were determined using immunohistochemical.Western blot analysis was performed to detect the expression of Caspase-3 protein. Results MTT assay showed that DADS inhibited the growth of CNE1 cells.Partial cells presented characteristic morphological changes...
