Origin:
The Humanized CYP3A4/3A7 Mouse model was developed by TaconicArtemis in collaboration with CXR Biosciences. The model was created by four consecutive rounds
of transfection in C57BL/6NTac-derived ES cells. First, mouse exon 1 and 2 of Cyp3a57 was replaced with a hygromycin cassette containing
a loxP, lox5171 and frt site through gene targeting. Second, a neomycin cassette with a loxP and f3 site was inserted into intron 4 of the Cyp3a59 gene
through gene targeting. Third, transfection of the ES cells with cre recombinase resulted in the deletion of the
Cyp3a57, Cyp3a16, Cyp3a41, Cyp3a44, Cyp3a11, Cyp3a25 and Cyp3a59 genes. Fourth, a modified human bacterial artificial chromosome carrying
CYP3A4 and CYP3A7 was inserted by cre-mediated recombination into the loxP and lox5171 sites in the mouse Cyp3a locus. The targeted ES cells were injected
into BALB/cJBomTac blastocysts and the resultant chimeras were backcrossed to a Flpe deleter strain on C57BL/6J to eliminate selection markers.
Taconic received stock in 2008, and the line was embryo transfer derived. The colony is maintained by mating homozygotes.
