Abstract

The invention relates to a plasmid-type adenovirus vector pAd-PPARGC1A (peroxisome proliferator-activated receptor gamma coactivator 1 alpha) and a construction method thereof, and belongs to the technical field of gene engineering. The construction method is as below: inserting a Qinchuan cattle PPARGC1A gene under a CMV promoter of a pAdTrack-CMV shuttle plasmid to construct a recombinant shuttle plasmid pAdTrack-CMV-PPARGC1A; linearizing by PmeI and transforming E.coli BJ5183 competent bacteria containing pAdEasy-l adenovirus backbone plasmids; carrying out homologous recombination on the pAdTrack-CMV-PPARGC1A and the pAdEasy-1 in bacteria, by using an efficient homologous recombination system of an E.coli BJ5183 endogenous Cre recombinase; naming a correct recombinant adenovirus plasmid after pAd-PPARGC1A; linearizing the pAd-PPARGC1A by Pac I and exposing inverted terminal repeats (ITR); and transfecting HEK-293A cells by the liposome to produce recombinant virus particles. The present invention has advantages of ensuring biological safety of the recombinant adenovirus vector, promoting efficient expression of the gene and benefiting expression of the gene for subsequent detection.

Description

technical field [0001] The invention belongs to the technical field of genetic engineering and relates to a plasmid-type adenovirus vector pAd-PPARGC1A and a construction method thereof, in particular to a plasmid-type adenovirus vector containing a cattle PPARGC1A gene and a construction method of the plasmid-type adenovirus vector. Background technique [0002] The AdEasyTM system is a shortcut system constructed by T.C.He et al. (1998) to replace the traditional adenovirus recombination system. In this system, recombinant adenoviruses can be produced in only two steps: first, the expression cassette is loaded into the shuttle vector, and then inserted into the adenoviral genome by homologous recombination. The most effective way to insert foreign genes into adenovirus is through homologous recombination, because: 1) adenovirus DNA is a large linear molecule containing almost all restriction enzyme sites; [0003] 2) The genome is too large (36kb) and difficult to manipul...
