In order to produce transgenic mice carrying the latent membrane protein(LMP) gene of Epstein-Barr virus(EBV) and to study the oncogenic role of LMP gene in vivo, three different transgenic vectors carrying the LMP gene were constructed. In pBR322-MT-LMP vector, the promoter of LMP gene is the regulation region of mouse metallothionein-I gene. In pMci3-LMP shuttle vector, the promoter of LMP gene is the replication origin(oriP) of EBV. In pMV-LMP-c-myc retroviral vector, the long terminal repeat (LTR) of mouse sarcomavirus serves as the promoter of LMP gene. The characterization and usefulness of these three transgenic vectors are also discussed.
为了培育携带爱泼斯坦 - 巴尔病毒(EBV)潜伏膜蛋白(LMP)基因的转基因小鼠,并在体内研究LMP基因的致癌作用,构建了三种携带LMP基因的不同转基因载体。在pBR322 - MT - LMP载体中,LMP基因的启动子是小鼠金属硫蛋白 - I基因的调控区。在pMci3 - LMP穿梭载体中,LMP基因的启动子是EBV的复制起点(oriP)。在pMV - LMP - c - myc逆转录病毒载体中,小鼠肉瘤病毒的长末端重复序列(LTR)作为LMP基因的启动子。还讨论了这三种转基因载体的特性和用途。
