AbstractAIM:To construct recombinant adenovirus expression vector containing Epstein-Barr virus (EBV) latent membrane protein 2A (LMP2A) and investigate the effects of LMP2A on the proliferation of human gastric cancer cell line.
METHODS: The target gene LMP2A was amplified by reverse transcription-polymerase chain reaction (RT-PCR), and the recombinant adenovirus vector carrying LMP2A gene was constructed with AdEasy system. The recombinant adenovirus vector pAd-2A was transfected into HEK293 cells with lipofectamine 2000 to package recombinant adenovirus, and then gastric cancer cells SGC with negative EBV were infected by recombinant adenovirus. The expression of LMP2A and its effect on the proliferation of SGC cells were analyzed by PT-PCR, MTT assay, fluorescence activated cell sorting (FACS) and confocal microscopy.
RESULTS:The recombinant adenovirus vector pAd-2A was successfully constructed and identified by PCR, restrictive enzyme analysis, and DNA sequencing ......
