Strain Description
Presenilin-1 is the major gene responsible for early-onset familial Alzheimer's disease. Mice that are homozygous null for this gene die within minutes after being born. Externally, mice exhibit shortened tails that curve to the right, thickened necks, loose skin and hind limbs that curve towards the midline. Their weight is 15-20% that of wildtype. Gross skeletal malformations and central nervous system abnormalities are observed. Death presumably results from impaired respiratory mechanics due to ribcage deformities. Histological examination indicates that alveoli are marginally expanded. By embryonic day 9.5, there is a drastic reduction in neural progenitor cells. Later, the brain exhibits hemorrhages and symmetric cerebral cavitation. Cavitation occurs primarily in the ventrolateral region of the ventricular zone in the posterior portion of the brain.

Strain Development
A targeting construct containing a neomycin cassette was electroporated into ES cells. The construct was designed to disrupt exons 2 and 3. ES cells were injected into C57BL/6 blastocysts. Resulting animals generate aberrant mRNA splice products, but no protein is detected.

Strain of Origin129S7/SvEvBrd-Hprt1b-m2
ES Cell Line NameAB2.1
ES Cell Line Strain129S7/SvEvBrd-Hprt1
Gene Symbol and Name Psen1, presenilin 1
Chromosome 12
Gene Common Name(s) AD3; Ad3h; FAD; PS-1; PS1; S182; alzheimer disease 3 homolog; presenilin-1;
Molecular Note Exon 3 of the Psen1 gene, encoding the translation initiation codon, was deleted and replaced with a neomycin cassette. Northern blots of brain tissue from homozygous mutant mice showed a small amount of mutant Psen1 mRNA, smaller in size than wild type Psen1. IP-Western blotting detected no C-terminal protein fragment in homozygous mutant mice. The authors conclude that this mutant is a null allele. [MGI Ref ID J:40365]

Supply Details

Standard SupplyRepository-Cryopreserved. Must Be Recovered. Please refer to pricing and supply notes for further information.
Supply Notes Cryorecovery - Standard.
The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery.

Cryorecovery to establish a Dedicated Supply for greater quantities of mice.
One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services: Tel: 1-800-422-6423 or 1-207-288-5845; Email: jaxservices@jax.org.

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.
