摘要: 目的:探讨Taurolidine对小鼠黑色素瘤B16-4A5细胞的生长抑制及其诱导凋亡的作用机制。方法: MTT法检测Taurolidine对B16-4A5细胞生长的影响,流式细胞仪检测细胞凋亡,Western blotting检测Bcl-2家族蛋白表达水平,ApoTarget试剂盒检测caspase-9活性。结果:Taurolidine对小鼠B16-4A5细胞生长有显著的抑制作用,并能显著诱导细胞发生凋亡,其作用呈明显的量效和时间依赖性关系。Taurolidine能明显提高促凋亡蛋白(Bax和Bad)表达水平,抑制抗凋亡蛋白(Bcl-2)水平。结论: Taurolidine通过调节Bcl-2家族蛋白及激活caspase-9诱导小鼠B16-4A5黑色素瘤细胞凋亡,抑制细胞增殖。

Abstract: To investigate the effects of Taurolidine on the apoptosis of melanoma B16-4A5 cells in mice and its mechanism. Methods The cell growth, apoptosis, Bcl-2 family protein expressions and caspase-9 activity were assessed with MTT method, flow cytometry, Western blotting and ApoTarget kit, respectively. Results Taurolidine had significantly inhibitory effect on B16-4A5 cell growth, and induced the apoptosis in a dose- and time- dependent manner. Taurolidien increased the expression levels of Bax and Bad and decreased the expression level of Bcl-2, and further activated caspase-9. Conclusion Taurolidine can inhibit B16-4A5 cell growth and induce apoptosis by mediation of Bcl-2 family proteins and activation of caspase-9.
