title: [Construction of recombinant adenovirus vector carrying human TIMP-1 cDNA and its expression in vitro].
abstract: The full-length cDNA of hTIMP-1 was obtained from a surgical patient with HCC by the method of RT-PCR. Then it was cloned into the adenoviral shuttle plasmid pAdTrack-CMV, and subsequently cotransformed into competent BJ5183 cells with the adenoviral backbone plasmid pAdEasy-1. Thereupon, a recombinant adenoviral plasmid containing full-length cDNA of hTIMP-1 was generated by homologous recombination in E. coli. The adenoviruses (AdhTIMP-1) were packaged and amplified in adenoviral packaging cells HEK 293. Then the viral titer was checked by green fluorescent protein (GFP), and the expression of hTIMP-1 was detected by the techniques of Western blot and RT-PCR. The recombinant adenovirus vector carrying human TIMP-1 was successfully constructed and expressed in vitro and may pave the way for further application in liver gene therapy.
