摘要 目的:研究二甲基亚砜(DMSO)对人肺癌细胞凋亡的诱导作用。方法:用不同浓度的DMSO处理体外培养的人肺癌细胞A549,应用普通光镜、荧光显微镜、MTT分析方法和流式细胞技术(FCM)检测肺癌细胞凋亡的形态学变化、细胞存活率、凋亡百分率和细胞周期分布的变化。结果:DMSO诱导A549细胞核DNA凝缩和核片段化,最后形成凋亡小体;随着DMSO浓度的增加和处理时间的延长,细胞存活率明显下降,其IC50为3.2%;4%的DMSO处理细胞 12h,凋亡率高达33.0%;同时G0/1期细胞明显憎加,S期和G2/M期细胞明显下降。结论:DMSO可诱导人肺癌细胞凋亡,并使细胞受阻于G0/1期而进入凋亡程序。 Objective: In order to study the apoptosis inducing function of dimethyl sulfoxide (DMSO) in human lung cancer cells A549. Methods: Light-and fluorescence microscope, MTT assay and flow cytometry (FCM) were used to determine morphological changes, cell viability apoptosis rate and cell cycle distribution. Results: DMSO induced the chromatin condensation, nuclear fragmentation and the formation of apoptotic body at the concentrations. Cell viability decreased with raised concentrations and prolonged treatment of DMSO; the IC50 was 3.2%; apoptosis rate was 33. 0% when the cells Were treated with 4% DMSO for 12h, at the same time, the cells in G0/1 phase increased and the number of cells in S and G2iM phase decreased. Conclusion: DMSO induces apoptosis and blockes the cell cycle at G0/1 phase in human lung cancer cells A549.
