摘要: 检测甲基丙烯酸环氧丙酯 (glycidyl methacrylate,GMA)致人支气管上皮细胞 (16HBE)恶性转化相关DNA修复基因表达改变的情况,以探讨GMA致细胞癌变的机制。 方法: 采用“基因组稳定和DNA修复基因芯片”分析检测GMA诱导16HBE细胞恶性转化过程中,经鉴定具备恶性细胞表型特征的第30代转化细胞DNA修复基因表达的改变。 结果: GMA转化第30代细胞与同代龄对照细胞比较,在113个基因中有8个基因的表达有显著差异,其中7个基因表达上调 (ratio>2),分别是NBN、RAD50、RAD51、OGG1、XAB2、TOP3A、TNKS;NEIL2基因表达下调 (0

Abstract: To observe the expression change of malignant transformation- related DNA repair genes in human bronchial epithelial cells (16HBE) induced by glycidyl methacrylate (GMA). METHODS:The expression of DNA repair genes in 30th generation cells which had malignant cell phenotype was evaluated with the gene chip of “human genome stability/DNA repair microarray”. RESULTS:Compared with control cells in the 30th generation,eight genes screened from 113 genes showed different expressions in cells induced by GMA. Among the eight genes,there were 7 genes (NBN,RAD50,RAD51,OGG1,XAB2,TOP3A,TNKS) with increased expression (ratio>2)and 1 gene (NEIL2) with lower expression (0
