Description
The targeted allele (PS1M146VKI) causes a mutation of the mouse Psen1 gene that results in expression of a presenilin-1 protein with the human familial Alzheimer's disease-linked mutation PS1M146V. The neo cassette was deleted from the targeted allele (using a CMV-Cre transgenic line of mice). Published findings indicate that this alteration should not influence the level of expression of mutant PS1. Northern blot analysis and RT-PCR determined mRNA expression of the targeted mutant allele is normal. Homozygous PS1M146VKI mice produce only the mutant gene product. Mice that express this targeted allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Neurodegeneration seen in wild-type mice caused by excitotoxin kainate treatment is increased and accelerated in this mutant strain. Cultured cells expressing the mutant protein exhibit perturbed neuronal calcium homeostasis. This mutant mouse strain represents a model that may be useful in studies of familial Alzheimer's disease in humans.

Development
A targeting vector containing neomycin resistance and herpes simplex virus thymidine kinase genes was utilized in constructing this mutant. A mutagenized DNA sequence of exon 5 of the mouse Psen1 gene was targeted for the Psen1 allele. The construct was electroporated into 129X1/SvJ x 129S1/Sv-derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric male animals were bred to C57BL/6 females to produce mice heterozygous for the mutation. These mice were then bred to a CMV-cre transgenic strain to delete the neo cassette from the targeted allele.

Molecular Note		Point mutations were introduced into the coding region of exon 5 that altered the codons corresponding to amino acids 145 and 146 from isoleucine and methionine to valine and valine, respectively. A lox-P flanked neomycin cassette was also introduced into exon 4. F2 mice exhibited the expected polymorphism of the targeted allele when genomic DNA was amplified with exon 5 specific primers and the products were digested with the appropriate restriction enzyme. Northern blot analysis of total brain RNA using a Psen1 specific antibody showed that the targeted allele was expressed at normal physiological levels in homozygous mutant mice. [MGI Ref ID J:51950]

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.

"PRODUCTS" means biological materials supplied by JACKSON, and their derivatives. "RECIPIENT" means each recipient of MICE, PRODUCTS, or services provided by JACKSON including each institution, its employees and other researchers under its control. MICE or PRODUCTS shall not be: (i) used for any purpose other than the internal research, (ii) sold or otherwise provided to any third party for any use, or (iii) provided to any agent or other third party to provide breeding or other services. Acceptance of MICE or PRODUCTS from JACKSON shall be deemed as agreement by RECIPIENT to these conditions, and departure from these conditions requires JACKSON's prior written authorization.

In case of dissatisfaction for a valid reason and claimed in writing by a purchaser within ninety (90) days of receipt of mice, products or services, JACKSON will, at its option, provide credit or replacement for the mice or product received or the services provided.

No Liability

In no event shall JACKSON, its trustees, directors, officers, employees, and affiliates be liable for any causes of action or damages, including any direct, indirect, special, or consequential damages, arising out of the provision of MICE, PRODUCTS or services, including economic damage or injury to property and lost profits, and including any damage arising from acts or negligence on the part of JACKSON, its agents or employees. In purchasing or receiving MICE, PRODUCTS or services from JACKSON, purchaser or recipient, or any party claiming by or through them, expressly releases and discharges JACKSON from all such causes of action or damages, and further agrees to defend and indemnify JACKSON from any costs or damages arising out of any third party claims.

MICE and PRODUCTS are to be used in a safe manner and in accordance with all applicable governmental rules and regulations.

The foregoing represents the General Terms and Conditions applicable to JACKSON’s MICE, PRODUCTS or services. In addition, special terms and conditions of sale of certain MICE, PRODUCTS or services may be set forth separately in JACKSON web pages, catalogs, price lists, contracts, and/or other documents, and these special terms and conditions shall also govern the sale of these MICE, PRODUCTS and services by JACKSON, and by its licensees and distributors.

Acceptance of delivery of MICE, PRODUCTS or services shall be deemed agreement to these terms and conditions. No purchase order or other document transmitted by purchaser or recipient that may modify the terms and conditions hereof, shall be in any way binding on JACKSON, and instead the terms and conditions set forth herein, including any special terms and conditions set forth separately, shall govern the sale of MICE, PRODUCTS or services by JACKSON.
