  • This targeted mutation strain carries a replacement of the mouse Nr1i3 gene which encodes for the nuclear receptor CAR with the corresponding human orthologous gene.
  • Useful in prediction of CYP induction and therefore pharmacokinetics, drug toxicity, and efficacy in humans.

Origin:

The Humanized CAR Mouse was developed by Taconic in collaboration with CXR Biosciences. It was created through a knock in of a human CAR construct containing the genomic sequence from the translational start site on exon 2 to exon 9 onto the ATG of murine Car in C57BL/6NTac-derived ES cells. The expression of the human CAR receptor is driven by the mouse Car promoter. 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 the selection marker. Taconic received stock in 2009, and the line was embryo transfer derived. The colony was maintained by mating homozygotes.
