Construction and identification of recombinant adenovirus carrying human TIMP-1shRNA gene

Genet Mol Res. 2015 Jan 16;14(1):199-208. doi: 10.4238/2015.January.16.3.

Abstract

The aim of this study was to construct the recombinant adenovirus carrying human TIMP-1shRNA gene expression system for preliminary identification to lay the foundation for the further study of gene therapy. Using the Adeno-X system, the recombinant adenovirus plasmid pAdeno-X green fluorescent protein (GFP)-tissue inhibitor of metalloprotease (TIMP)-1 small hairpin (1shRNA) was constructed by including the target gene fragment of the TIMP-1shRNA shuttle plasmid pShuttle2-GFP-TIMP-1shRNA and the backbone plasmid pAdeno-X by homologous recombination in Escherichia coli. Recombinant plasmids were transfected into HEK293A cells to package the recombinant adenovirus rvAdeno-XGFP-TIMP-1shRNA. The recombinant adenovirus was identified by polymerase chain reaction, and the viral titer and infection efficiency were detected using GFP. Polymerase chain reaction and restriction endonuclease digestion demonstrated that rvAdeno-XGFP-TIMP-1shRNA had been successfully constructed, which has a strong ability to infect the kidney. The TIMP-1shRNA adenovirus expression vector was successfully constructed using homologous recombination methods.
