Genetic Alterations
For iNOS knockout, donor deleted 585bp of promoter plus exons 1-4 while inserting neo cassette (Cell 81: 641, 1995). The transgenes were introduced by others into separate strains and brought together with the ko as described above. "Recessive" designation below refers to disrupted iNOS alleles.

    Strain Development
    First, donor backcrossed the original iNOS-/- C57BL/6129 mice (30) to C57BL/6 for 6 generations. Descendants of brother-sister matings of the latter mice were crossed with the SJL strain and their progeny interbred to derive iNOS-/- C57BL/6SJL mice. This step was based on evidence that that modifier genes from the SJL background were critical to avoid premature mortality in C57BL/6 mice bearing a mutant (K670N, M671L) human amyloid precursor protein (APP) transgene (31). Donor bred the iNOS-/- C57BL/6SJL mice with a strain called Tg2576 in which a hamster prion promoter drives the K670N, M671L APP transgene in the C57Bl/6SJL background (32), and also with transgenics in which the Thy1 promoter drives human presenilin-1 (hPS1) with the A246E mutation in the C57Bl/6SJL background (33). Donor interbred the progeny to establish three C57BL/6SJL sublines from littermates: (i) wild type mice (iNOS+/+ hAPP0/0 hPS10/0); (ii) mice with wild type iNOS alleles and the APP and PS1 transgenes, each of which was inherited from only one parent so as to avoid overdose (iNOS+/+ hAPP+/0 hPS1+/0); and (iii) mice with disrupted iNOS alleles and the APP and PS1 transgenes (iNOS-/- hAPP+/0 hPS1+/0).
