摘要
目的:研究低浓度N-甲基-N-硝基-N-甲基亚硝基胍对人羊膜FL细胞部分基因表达的影响,以助于阐明MNNG引起细胞应答反应的基因及其调控机制。方法:用ABI公司的高通量实时荧光定量PCR方法,检测FL细胞在0.2μmol/LMNNG处理后基因表达发生的改变。数据用ABI公司的SDS2.1软件分析。结果:MNNG处理后,在检测的95个基因中,29个基因表达发生改变,其中14个基因下调2倍以上,15个基因下调在1.5-2倍之间;其中有4个基因与细胞周期相关,6个基因与信号转导相关,6个基因与转录调节相关。结论:在低浓度MNNG攻击后,FL细胞的基因表达发生了显著的变化。
AIM: To study the gene expression changes of 95 genes in human FL cells after treatment with low concentration of N - methyl - N' - nitro - N - nitrosoguanidine (MNNG) in order to elucidate the response genes and regulatory mechanism of human FL cells exposed to MNNG. METHODS: C, ene expression of human FL cells treated with 0. 2μmol/L MNNG was detected by high throughput real- time PCR. Data were analyzed by SDS 2. 1 software. RESULTS:26 of 95 genes showed significant change in cells after MNNG treatment. The mRNA expression level demore than 2 fold in 14 of 26, and 1.5 to 2 fold in another 15 genes. There were 6 cell cycle related genes, 6 signal transduction related genes and 6 transcription regulation related genes in the 29 genes. CONCLUSION: There are significant alterations of gene profile in human FL cells after low concentration of MNNG attack.
