Strain Description
These transgenic mice express all mRNA and protein isoforms of the human amyloid beta (A4) precursor protein APP containing the Familial Alzheimer's Disease (FAD) Swedish mutation K670N/M671L. Transgene expression (mRNA and full-length protein) is 2 to 3 fold the wild-type mouse App expression level in the hemizygous state in brain tissue as revealed by RT-PCR and Western Blot analysis. Transgene expression pattern mimics wild-type mouse gene expression patterns. This mutant mouse strain represents a model that may be useful in studies of the pathogenesis of Familial Alzheimer's Disease and possible therapeutic treatments.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. A publication (Lehman et al. 2003 Hum Mol Genet 12:2949) compares the well characterized B6-R1.40 strain (C57BL/6J congenic, see Stock No. 005300) with two additional congenic strains, D2-R1.40 (DBA/2J congenic, see Stock No. 006472) and 129S1-R1.40 (129S1/SvImJ congenic, see Stock No. 006409). While these three congenic strains have similar levels of holo-APP in brain tissue, the levels of brain APP C-terminal fragments (CTFs) vary depending upon genetic background. Brain and plasma levels of amyloid beta-40 and -42 are variable as well (B6-R1.40 > 129S1-R1.40 > D2-R1.40). In addition, the congenic strains exhibited dramatic alterations in the age of onset of amyloid beta deposition; in contrast to 14 month old homozygous B6-R1.40 mice, homozygous D2-R1.40 and 129S1-R1.40 mice do not develop amyloid beta deposits in the parietal or frontal cortex even by 20 months of age. The donating investigator further reports that the A-R1.40 strain (A/J congenic, see Stock No. 006555) exhibits levels of amyloid beta comparable to the B6-R1.40 strain, but with later onset. Therefore, APP processing and amyloid beta metabolism and deposition are modified by the genetic background. While the 129S1-R1.40 strain can be easily maintained as homozygotes, the donating investigator reports increased mortality in young homozygotes on the other genetic backgrounds, with D2-R1.40 and A-R1.40 more severely affected than B6-R1.40.

Strain Development
A 650 kb YAC transgene containing the entire human amyloid beta (A4) precursor protein (APP) gene, and approximately 250 kb of flanking sequence, was altered to include the Swiss mutation K670N/M671L associated with Familial Alzheimer's Disease (FAD). This transgene was injected into (129X1/SvJ x 129S1/Sv)F1-derived R1 embryonic stem (ES) cells. Founder animals (line R1.40) were established and bred to C57BL/6J for an unknown number of generations. The mice were next bred to DBA/2J for seven generations. After this, transgenic mice were bred to 129S1/SvImJ (Stock No. 002448) for at least 24 generations prior to arrival at The Jackson Laboratory. This transgene inserted on Chromosome 13.

Molecular Note The transgenic insertion comprises four to eight copies of a 650-kb YAC containing the entire 400-kb human amyloid precursor protein gene with the Swiss familial Alzheimer disease (FAD) mutation and approximately 250 kb of flanking human DNA. The double mutation (K670N/M671N) comprises a G-to-A transition converting the lysine codon at position 670 to an asparagine codon and an A-to-C transversion replacing the methionine at amino acid 671 with leucine. RT-PCR and western blot analysis revealed that hemizygous transgenic mice express all major human APP mRNA and protein isoforms in brain, in parallel with the corresponding mouse versions, at approximately three times the levels of the latter. Total brain levels of the Alzheimer disease- associated 42-amino acid amyloid-beta peptide detected by ELISA are 7-8-fold and 15-20-fold higher, respectively, in mice hemizygous and homozygous for the mutant gene than in hemizygotes for the wildtype human gene. Levels of a cell-associated, beta-secretase-generated 13.5 kDa C-terminal peptide containing the amyloid beta domain and of soluble amyloid beta peptides are significantly elevated in brains of mice with the mutant, versus wildtype, transgene, while alpha-secretase products are diminished.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
