FENG Tao, et al. Construction of a recombinant adenovirus vector containing HBX gene[J]. Journal of Chongqing Medical University, 2004,(3):273-275. DOI: 10.13406/j.cnki.cyxb.2004.03.006.
Objective:To establish a recombinant adenovirus vector carrying HBX gene for investigation of the functions of HBX gene on the hepatocellular carcinoma.Methods:HBX gene was amplified from genomic DNA of HBV by polymerase chain reaction(PCR) technique
and subcloned to plasmid pHAHA to construct recombinant plasmid pHAHA-HBX.subcloned HAHA-HBX into a shuttle vector pAdTrack-CMV.After being identified by endonuclease
and subsequently cotransformed into E.coli.293 cells with an adenoviral backbone plasmid
e.g.pAdEasy-1.Results:HBX gene was cloned from HBV genome by PCR successfully
and proved by sequence determination.A vector producing cell line 293/HBX was established.An HBX gene integration was detected by PCR in the recombinant adenovirus vectors.Conclusion:A recombinant adenovirus vector containing HBX gene was successfully constructed.
