Construction and identification of human p16 gene recombinant adenovirus

Objective To construct the recombinant adenovirus encoding human p16 gene for future gene therapy.Methods The human p16 gene fragment was cloned into the shuttle plasmid pAdTrack-CMV to form the transfer vector by the method of homogenous recombination in bacteria.Then the recombinant adenovirus was transfected into 293T cells using Lipofectine DOTAP.The target gene was detected by polymerase chain reaction(PCR).The titer and its infection rate were determined using the green fluorescent protein(GFP) expression in the shuttle plasmid.Results Restriction endonuclease and PCR analysis confirmed that the human p16 gene was successfully inserted into the adenovirus vector.The titer of the recombinant adenovirus was 6.1×10~(10)pfu/ml.The adenovirus has a strong effect on human fibroblast cells.Conclusion The recombinant adenovirus containing human p16 gene was successfully constructed by the method of homogenous recombination in bacteria.
