As the pMCLacI/neo shuttle vector is a novel bi-functional mutation detection system, apart from be used in above transgenic animal study , it was also used in our study of MNNG-indued DNA damage and repair research.

• 由于本研究率先在突变检测系统中应用了具有双功能的pMCLacI/neo穿梭载体,在利用转基因动物技术建立突变检测系统及展开相关研究的同时，我们又利用基因敲除技术，定向敲除DNA损伤修复酶基因-MGMT，建立了一系列MGMT基因定向敲除的突变检测系统，及高表达MGMT的突变检测系统，并展开了相应的DNA损伤修复的研究。
