【摘要】 目的:探讨白细胞介素2(interleukin2,IL-2)对宫颈癌细胞系HeLaS3表达免疫球蛋白G(immunoglobulin G,IgG)的影响。方法:用免疫荧光-流式细胞术(flow cytometry,FCM)检测IL-2刺激后HeLaS3胞膜和胞内IgG表达变化;用Western blot检测IL-2刺激HeLaS3后IgG的表达变化;用同时能扩增IgG四个亚类的引物,以RT-PCR法,从mRNA水平检测IL-2刺激后,HeLaS3γ链转录水平的变化。结果:免疫荧光-FCM结果显示,IL-2刺激48h后HeLaS3胞膜和胞内IgG表达明显上调;Western blot结果显示IL-2刺激48h后HeLaS3胞内IgG表达水平明显上调;RT-PCR显示IL-2刺激48h后HeLaS3γ链转录水平有所上升。结论:IL-2能促进HeLaS3IgG的表达。更多还原

【Abstract】 Objective:To analyze the effect of interleukin 2(IL-2) on immunoglobulin G(IgG) expression in cervical cancer cell line HeLaS3.Methods:By immunofluorescence-flow cytometry(FCM),we detected membrane and cytoplasmic IgG expression variation of HeLaS3 after IL-2 stimulation.By western blot,we detected IgG expression variation of HeLaS3 after IL-2 stimulation.Meanwhile,by RT-PCR with primers designed to amplify four subclasses of IgG,we detected γ transcript variation in HeLaS3 after IL-2 stimulation at mRNA level.Results:The result of immunofluorescence-FACS showed that after IL-2 stimulation for 48 hours,membrane and cytoplasmic IgG expression elevated in HeLaS3.The result of Western blot showed after IL-2 stimulation for 48 hours,IgG expression elevated in HeLaS3.Meanwhile,the result of RT-PCR showed that γ1 transcript mildly elevated after IL-2 stimulation for 48 hours.Conclusion:IL-2 can promote IgG expression in cervical cancer cell line HeLaS3.更多还原
