Transgene
description
Transgene Type:    Transgenic (Humanized sequence, Inserted expressed sequence)
Mutation:    Insertion
 
Tg(APP695)3Dbo expresses 1 gene
 
Mutation detailsThe transgene is composed of a cDNA encoding a chimeric APP protein regulated by the mouse prion promoter. The chimeric APP molecule was created by replacing sequences encoding the Abeta domain of a 695 amino acid isoform of the murine sequence with the cognate sequences of the human gene (mutations K595N, M596L). The human mutations are found in familial Alzheimer's disease. Transgene expression was observed in the brain and heart by Western blot analysis using a monoclonal antibody recognizing the human Abeta region. (J:80782)

Notes
Three transgenic lines were generated and designated by the authors lines Q2-2, E1-2 (Tg(Prnp-App/APPswe)E1-2Dbo) and C3-3.

This line was generated from founder number C3-3.

Transgenic mice develop amyloid deposits in brain tissue by 18-20 months of age.

Transgenic mice that are also transgenic for Tg(PSEN1)5Dbo express both human presenilin 1 (A246E variant) and a chimeric amyloid precursor protein (APPSwe) under direction of the mouse prion protein promoter. Elevated levels of the AB1-42(43) peptide are detected in brain homogenates. By nine months of age, histological examination of brain tissue from these mice reveals numerous amyloid deposits resembling those observed in the brains of patients with Alzheimer's disease (AD). The number of amyloid deposits increases dramatically between the ages of 10 and 12 months.
