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

Phenotype

Homozygous phenotype: ROSA NOTCH3-455 mice are viable, fertile, with the CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy)-associated C445R mutation inserted into the Gt(ROSA)26Sor locus. Expression of the mutated human NOTCH3 is blocked by an upstream loxP-flanked STOP sequence. When bred to cre expressing mice, the STOP sequence is deleted in the tissues of offspring where Cre recombinase is present, resulting in mutated human NOTCH3 expression and expression of nuclear-enhanced green fluorescent protein (GFP). Expression in vascular smooth muscle cells is characterized by cell degeneration and the presence of granular osmiophilic deposits. These mice allow inducible expression of a human mutation associated with ischemic stroke.

Heterozygous phenotype: Not evaluated, however, heterozygote phenotype is expected to be similar to homozygote phenotype.

Strain of Origin: 129S6/SvEvTac

Strain genetic background: 129S

Strain Development: A targeting vector was designed with a splice acceptor site, a loxP-flanked PGK neomycin cassette, a human NOTCH3 cDNA encoding a CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy)-associated mutation and an IRES-nuclear EGFP sequence at was inserted into the GT(ROSA)26Sor locus. The CADASIL mutation is an amino acid substitution from cysteine to arginine at amino acid 455 (C455R). The construct was introduced into 129S6/SvEvTac -derived W4 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting "455" chimeric animals were crossed to 129S2/SvEv mice. The mice were crossed to 129S2/SvEv for an unknown number of generations. Upon arrival, mice were bred to 129S1/SvImJ for at least 1 generation to establish the colony.

Suggested Control Mice: Wild-type littermates

Colony and Husbandry Information

Special Considerations

While maintaining a live colony, these mice are bred as homozygotes.

Health Status Report

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email csmmrrc@jax.org.

Order Request Information

Availability Level

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

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.

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.
