Strain Description [Including phenotype, strain background, strain development and suggested control mice]

Phenotype

Homozygous phenotype: Not evaluated
Hemizygous phenotype: Double transgenic mice are viable and fertile. At 6 months of age, double-transgenic mice show visible amyloid plaque deposition but are indistinguishable from nontransgenic animals in all cognitive measures. By 18 months, amyloid deposits were much higher in APPswe/PS1dE9 mice with statistically significant but mild decreases in cholinergic markers (cortex and hippocampus) and somatostatin levels (cortex). Performance of older double-transgenic mice is impaired in all cognitive tasks, and deficits in episodic-like memory tasks correlate with total amyloid-beta peptide loads in the brain. Mutant mice, hemizygous for each transgene, and on the C57BL/6J background (N6), have altered EEG (decreased cortical theta activity and increased beta and gamma activity). EEG differences are detected as early as 7 month of age (Wang et al. Brain Res 2002).

Strain of Origin: C3B6

Strain genetic background: B6.Cg

Strain Development: Mutant amyloid precursor protein (APPswe) transgenic mice (line C3-3) express a chimeric mouse/human APP-695 with mutations linked to familial Alzheimers disease (KM 593/594 NL). The C3-3 line was backcrossed to C57BL/6J mice for 10 generations. Presenilin 1 (PSEN1) transgenic mice (line S-9) express human PSEN1 carrying the exon-9-deleted variant (PSEN1dE9) associated with familial Alzheimer's disease. Originally created on a hybrid strain background (C3H/HeJ;C57BL/6J), the S-9 line was backcrossed to C57BL/6J for six generations. Both are under the control of the mouse prion protein (PrP) promoter, directing transgene expression predominantly to CNS neurons. APPswe/PS1dE9 double transgenic mice were produced by mating APP-695 line C3-3 males to PS1dE9 line S-9 females, and then backcrossing double transgenic males to C57BL/6J mice for >10 generations before arriving at The Repository.

Suggested Control Mice: Wild-ype littermates

Colony and Husbandry Information

Special Considerations

When maintaining a live colony, The Jackson Laboratory will maintain this line by mating (APP695/0, +/+) females with (+/+, PSEN1/0) males (or reciprocal). The transgenes are not linked (only 1 in 4 pups is a double transgenic); and the integration site is unknown.

Conditions of Distribution [Including applicable technology transfer agreements]

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

The donor or their institution limits the distribution to non-profit institutions only.

Fees

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

Non-Profit
Per Mouse The csmmrrc@jax.org may assess additional fees for any special requests (e.g., specific age or weight of mice, etc.).

1 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

3 An aliquot contains a sufficient number of embryos (in one or more vials and based on the transfer success rate of the MMRRC facility) to transfer to at least two recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
