Homozygous: Not evaluated
Hemizygous: These transgenic mice express a mutant form of the human amyloid protein precursor bearing both the Swedish (K670N/M671L) and the Indiana (V717F) mutations (APPSwInd). Expression of the transgenic insert is directed by the human platelet-derived growth factor beta polypeptide (PDGFB) promoter. Hemizygotes express immunodetectable transgene product in cerebral neurons, with the highest level of expression occurring in the neocortex and hippocampus. Enzyme-linked immunosorbent assay (ELISA) analysis reveals approximate total amyloid beta peptides and 42 amino acid length amyloid beta peptides in neocortical and hippocampal tissue from mutant mice. At five to seven months of age diffuse amyloid beta peptides deposition in the dendate gyrus and neocortex forms. Amyloid deposition is progressive with all transgenic mice exhibiting plaques by age eight to 10 months. Video-EEG monitoring of 4 to 7 month old hemizygous transgenic mice, N10+ on the C57BL/6J background, reveals hippocampal hyperexcitability and cortical and hippocampal spontaneous nonconvulsive seizures. The mice are immobile, with no myoclonic behavior observed, during the non-convulsive electroencephalographic seizures. Pentylenetetrazole induced seizures have earlier onset, are more severe and result in more frequent deaths (50% develop fatal status epilepticus) than wild-type controls (Palop et al. Neuron 2007). 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. Pups born of carrier females have shown an increased mortality rate in our colonies. The Donating Researcher has observed an approximately 15% mortality rate in the first 6 months of life.
Strain of Origin: (C57BL/6J X DBA/2)F2
Strain genetic background: B6.Cg
Strain Development: A transgenic construct containing the mutant human amyloid protein precursor APPSwInd under the control of human platelet-derived growth factor beta polypeptide, simian sarcoma viral (v-sis) oncogene homolog, (PDGFB) promoter, was injected into C57BL/6 X DBA/2 F2 one-cell embryos. Heterozygous founder animals were bred to C57BL/6 X DBA/2 F1 mice. The resulting transgenic mice were then backcrossed for 12 generations on the C57BL/6J background.
Suggested Control Mice: Wild-ype littermates or C57BL/6J mice

Fee/unit (US $)
|Per Mouse||The firstname.lastname@example.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.
