Genetic Alterations

For the nitric oxide synthase (Nos2) knockout, 585 bp of the promoter and exons 1-4 were deleted while inserting a neo cassette (PMID:7538909). Two additional transgenes were brought together with the KO, where (A) the gold hamster prion protein (Prnp) promoter drives the expression of human amyloid beta (A4) precursor protein (APP, NCBI Gene:351) with the Swedish mutation (K670N/M671L), and (B) the human thymus cell antigen 1, theta (THY1, NCBI Gene:7070) promoter drives the expression of human presenilin 1 (PSEN1, NCBI Gene:5663) with the A246E mutation. In this particular strain, the KO allele is not present through coordinated interbreeding (i.e., wild-type).

    Strain Development
    First, the donor backcrossed the original inducible nitric oxide synthase 2 knockout mice ("iNOS", Nos2 - MGI:97361, C57BL/6;129S7 - PMID:7538909) to C57BL/6 for six generations. Descendants of brother-sister matings were crossed with the SJL strain, and their progeny were interbred to derive a mix of B6/SJL/129S7 mice (officially STOCK designation since genetic components of >2 inbred lines are present without further backcrossing to congenicity). 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 APP transgene ("hAPP", PMID:8810256). The B6/SJL/129S7 mice were mated with "Tg2576" mice, in which the hamster prion promoter drives the K670N/M671L APP transgene in the B6;SJL background (PMID:15450355 and 8810256), and with transgenics in which the human THY1 promoter drives human presenilin 1 ("hPS1", PSEN1) with the A246E mutation in the B6;SJL background (PMID:9539133). The donor interbred the progeny to establish three sublines from littermates:

    1. wild-type mice (iNOS+/+/hAPP0/0/hPS10/0) - MMRRC:11169
    2. 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) - MMRRC:11170
    3. mice with disrupted iNOS alleles and the APP and PS1 transgenes (iNOS-/-/hAPP+/0/hPS1+/0) - MMRRC:11171
    Suggested Control Mice

    Wild-type littermates - MMRRC:11169
