摘要: 目的:探讨干扰素-γ(IFN-γ)对人肺癌A549细胞增殖和P21 分子的影响。方法:培养人肺癌A549 细胞, 与IFN-γ共孵育, 通过MTT 比色法观察IFN-γ对人肺癌A549 细胞增殖的影响, 同时通过免疫细胞化学法, 分析人肺癌A549 细胞中P21 蛋白表达的变化。结果:与对照组相比, IFN-γ组能够明显抑制细胞增殖且呈剂量依赖性, 同时免疫组化结果显示, IFN-γ可以上调P21 蛋白的表达。结论:IFN-γ可以增加P21 蛋白的表达, 抑制人肺癌A549 细胞增殖, 从而可能起到抗肿瘤的疗效。

Abstract: AIM: To observe the effect of IFN-γ on the A549 cell proliferation and the expression of P21 protein. METHODS: A549 cells were cultured and incubated with IFN-γ.MTT colorimetric method was used to observe the effect of IFN-γ on the A549 cell proliferation, and the change of P21 protein expression was observed by the immunocytochemistry.RESULTS: Compared with those of control group, the results of MTT showed that IFN-γ could reduce the A549 cell proliferation.From the experiment of immunocytochemistry, the expression of P21 protein increased significantly after treatment with IFN-γ.CONCLUSION: IFN-γ can induce the expression of P21 protein and inhibit the A549 cell proliferation and maybe provide the new idea for the therapy of lung cancer.

Key words: IFN-γ, A549 cells, apoptosis, lung cancer, immunotherapy
