Abstract:
Objective: To investigate in vitro the biological characteristics of AdCD80-infected human lung cancer cells on the basis of generation of replication-deficient hB7-1(CD80) recombinant adenovirus. Methods: Human CD80 gene was transduced into lung cancer cells mediated by recombinant adenovirus and then the expression of the gene was detected by PCR and agarose gel electrophoresis. The biological characteristics of the above cells were analysed with electron microscope, FACS and etc. Results: The titers of rAd reached to 10 10 PFU/ml and more than 90% Anip973 lung cancer cells could be infected by 30 MOI rAd. The growth curve and cloning efficiency of rAdCD80-infected Anip973 cells showed no significant difference compared with that of the control cells. The cell proliferation cycle of rAdCD80-infected 973 cells showed no change through FACS test. Having been infected by rAdCD80, the surface structure and ultrastructure of 973 cells had a little change. Conclusion: These results will lay foundation for tumor vaccines.
