Type JAX® GEMM® Strain - Targeted Mutation Type JAX® GEMM® Strain - Transgenic Mating System Noncarrier x Hemizygote (Female x Male) Species laboratory mouse Donating Investigator Eileen McGowan, Mayo Clinic College of Medicine Generation N1F0 (03-DEC-07) Strain Description
Mice hemizygous for this BRI-Abeta40 transgene are viable and fertile with a normal life span and no obvious behavioral abnormalities. Transgenic BRI-Abeta mRNA is expressed in a pattern characteristic of the mouse prion protein promoter; highest expression levels are detected in the cerebellar granule cells and hippocampus, followed by the cortex, pons, thalamus, and midbrain. Wildtype BRI protein is cleaved by furin or a furin-like protease near the COOH-terminus which releases a soluble 23 amino acid peptide. In the transgenic fusion protein, Abeta1-40 is fused to the C terminus of the BRI protein at the furin-like cleavage site such that cleavage results in efficient Abeta1-40 secretion into the lumen or extracellular space. Therefore, these mice specifically express the Abeta1-40 isoform in the absence of human amyloid beta protein precursor (APP) overexpression. In contrast to BRI-Abeta42 transgenic mice (Stock No. 007002), hemizygous BRI-Abeta40 mice expressing high levels of Abeta1-40 (80-120pm/gm at 3 months of age) neither develop overt amyloid pathology nor accumulate detergent-insoluble amyloid-beta. These mutant mice may be useful in neurological studies of Alzheimer's disease, neurodegeneration, and amyloid plaque formation.Strain Development
The BRI-Abeta40 transgene was generated with a mouse prion promoter upstream of a BRI-Abeta40 fusion construct. This fusion construct contained a cDNA sequence from human type 2 transmembrane protein (BRI or ITM2B) fused in-frame with a "wildtype APP695" cDNA sequence encoding amyloid-beta40 (Abeta40) at the furin-like cleavage site; the C-terminal 23 amino acid ABri peptide of BRI was replaced with the Abeta40 sequence. The transgene was injected into the pronuclei of single-cell embryos from C3B6F1 x B6 mice and then implanted into pseudopregnant females. A single founder line with the highest Abeta40 plasma levels, line 1d, was maintained on a mixed B6C3 background prior to arrival at The Jackson Laboratory.

| Molecular Note | The BRI-Abeta40 transgene was generated with a mouse prion promoter upstream of a BRI-Abeta40 fusion construct, containing a cDNA sequence from human type 2 transmembrane protein (BRI or ITM2B) fused in-frame with a "wildtype APP695" cDNA sequence encoding amyloid-beta40 (Abeta40) at the furin-like cleavage site; the C-terminal 23 amino acid ABri peptide of BRI was replaced with the Abeta40 sequence. A single founder line with the highest Abeta40 plasma levels (line 1d) was donated to The Jackson Laboratory. Transgenic fusion protein expression approximates levels of endogenous mouse APP expression and is expressed in patterns characteristic of the Prnp promoter, with highest expression in cerebellar granule cells and hippocampus. Full length Abeta fusion protein is most highly expressed with processed Abeta40 peptide expressed at lower levels. [MGI Ref ID J:101023] | ||

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.Ordering and Purchasing Information
