摘      要：The latent Epstein-Barr virus (EBV) is found in the cells of many *** example,EBVis detectable in almost all cases,and in almost all tumor cells,of non-keratinizing nasopharyngeal *** the latent virus,which will result in its lytic replication and the death of tumor cells,is a potentialapproach for the treatment of EBV-associated *** this study,three recombinant adenoviruses wereconstructed to express the Zebra gene,an EBV gene responsible for switching from the latent state to ***-specific promoters were used in order to limit Zebra expression in EBV-positive cells,andreduce the potential side *** EBV promoters used were Cp,Zp and a dual promoter combining *** Zebra protein was detected in HEK293 cells as well as the EBV-positive D98-HR1cells infected with recombinant *** EBV lyric replication early antigen,EA-D,was also detected ininfected D98-HR1,implying the initiation of lytic *** the cell viability assay,Zebra-expressingadenoviruses had little effect on EBV-negative HeLa cells,while significantly reducing the cell viability andproliferation of D98-HR1 *** results indicate that EBV virus promoters can be used in adenovirusvectors to express the Zebra gene and induce EBV lytic replication in D98-HR1 cells.
