| 摘 要： | 背景与目的:观察缺氧诱导对非小细胞肺癌细胞株A549凋亡及其Survivin 基因表达变化的影响.材料与方法:利用COCl2构建缺氧诱导模型,采用MTT法观察不同浓度CoCI2(0、50、100、200、400 μmol/L)作用A549细胞以及相同浓度CoOl2(200 μmol/L)作用不同时间(4、12、24 h)后,A549细胞增殖的变化,实验同时设对照组;荧光显微镜观察细胞核的形态变化;RT-PCR法检测A549细胞Survivin mRNA表达水平.结果:CoCl2作用A549细胞后,其生长抑制率呈现一定的时间、剂量依赖性,且随着CoCl2浓度的增加细胞的Survivin mRNA表达水平呈下降趋势.结论:缺氧能抑制AM9细胞增殖,并诱导其凋亡;Survivin基因表达水平的下降与缺氧诱导的细胞凋亡有关. |
