Adenovirus Mediated BIMS Transfer Induces Growth Supression and Apoptosis in Raji Lymphoma Cells

doi: 10.3967/bes2014.101

摘要: Objective To transfer pro-apoptotic BIM directly into tumor cells bypass the complicated biological processes of BIM activation so as to reverse the chemoresistance of cancer cells. Methods BIMS was specifically amplified from HL-60 cells by RT-PCR, confirmed to be correct by sequencing and cloned into shuttle vector pAdTrack-CMV carrying a green fluorescence protein gene to generate a recombinant plasmid pAdTrack-CMV-BIMS. This plasmid and adenovirus backbone plasmid pAdEasy-1 were linearized and electroporated into E.coli BJ5183 host bacteria to mediate homologous recombination. The positive clone was identified by restrict endonuclease digestion. The recombinant pAdEasy-CMV-BIMS was transferred into HEK293 cells for packaging and amplification. The successful construction of recombinant human BIMS adenovirus (Ad-BIMS) was demonstrated by Western blot. To test whether Ad-BIMS has the capability of inducing apoptosis of tumor cells, Ad-BIMS was used to infect GC resistant Burkitt lymphoma Raji cells. Results After infected for 2-5 days, BIMS expression in Raji cells was detected by RT-PCR and Western blot. The significant growth retardation and apoptosis of Raji cells were also observed by MTT and flow cytometry. Conclusion These results indicated that BIMS might be a potential candidate of gene therapy for chemoresistant tumor cells.
