摘要 目的探讨人和小鼠的IG-1R、PRKCZ基因启动子区DNA甲基化检测的方法。方法用亚硫酸氢钠处理人外周血白细胞基因组DNA及小鼠骨骼肌组织中DNA标本,以修饰后的DNA为模板,对人和小鼠两个不同基因分别设计合适的引物对启动子区进行Touch-Down PCR扩增,PCR产物进行克隆测序。结果在利用合适的引物对修饰后DNA模板进行扩增时均能扩增出目的片段,克隆测序结果显示IGF-1R、PRKCZ基因启动子区甲基化的胞嘧啶碱基C不变,而非甲基化的胞嘧啶碱基C转变为胸腺嘧啶碱基T。结论成功的建立了人和小鼠IGF-1R、PRKCZ基因启动子区甲基化的检测方法,为进一步探讨这两种基因启动子区甲基化与相关疾病的关系奠定基础。
