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).
