Name: transgene insertion 885, David R Borchelt
Alteration at locus: Transgenic
Promoter: tetO (Synthetic)
Name: tetracycline operon
Alteration at locus: Transgenic
ES Cell Line: Not Applicable
Homozygous phenotype: Homozygote phenotype is expected to be similar to hemizygote phenotype.
Hemizygous phenotype: Hemizygotes for this tetO-APPswe/ind transgene are viable and fertile. These transgenic mice express a chimeric mouse/human amyloid precursor protein (APP695) bearing the Swedish (KM570/571NL) and Indiana (V617F) mutations associated with Alzheimer's disease (APP695swe/ind) under the control of a tetracycline-responsive promoter element (TRE; tetO). When hemizygotes are bred with another transgenic mouse expressing either reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA) under the regulation of a tissue-specific promoter, APP695swe/ind expression can be regulated in the appropriate tissue of the bitransgenic offspring with the tetracycline analog doxycycline (dox). These tetO-APPswe/ind transgenic mice may be useful in studies of Alzheimer's disease and other neurodegenerative tauopathies.
Strain of Origin: B6C3
Strain genetic background: B6.Cg
Strain Development: The mouse amyloid beta (A4) precursor protein (App) sequence was first modified to contain a humanized amyloid-beta (Abeta) domain. This mouse/human chimeric APP (called mo/huAPP695 or APP695) was further mutated to incorporate the Swedish (KM570/571NL) and Indiana (V617F) mutations associated with Alzheimer's disease. This APP695swe/ind sequence was placed downstream of the tetracycline-responsive promoter (TRE; tetO) promoter and mouse prion protein exons 1-2. The complete tetracycline-responsive APP695swe/ind transgene (tet-APPswe/ind) was injected into the pronucleus of fertilized eggs from (C57BL/6J x C3HeJ) F1 matings. Transgene positive founders (line 885) were bred to transgenic Camk2a-tTA mice on a B6;CBA mixed genetic background. After 3-4 generations of brother-sister matings, mice harboring only the tet-APPswe/ind transgene were selected and backcrossed to C57BL/6 for at least 10 generations prior to arrival at The Repository.
Suggested Control Mice: Wild-ype littermates

When maintained as a live colony, hemizygous mice are bred to C57BL/6J or wildtype siblings.
Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.
Fee/unit (US $)
|Litter||Recovered litter1; additional fees for any special requests.|
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.
