Description
These transgenic mice express the human huntingtin protein containing a 133 CAG repeat expansion and a mutation in exon 13 conferring resistance to caspase-6 cleavage to the gene product. Expected caspase-6 cleaved fragments are not detected in brain lysates by Western blot analysis. Transgenic mice have brain weight and striatal volume similar to wildtype controls and do not exhibit neuronal loss at 12 months of age when compared to transgenic mice that express human huntingtin protein containing a 128 CAG repeat (FVB-Tg(YAC128)53Hay/J Stock No. 004938). These transgenic mice have activity levels and motor function similar to wildtype controls, and are resistant to neuron excitotoxicity. Immunohistochemical analysis of striatal brain sections reveals delayed nuclear localization of mutant huntingtin protein in these transgenic mice at 9 months of age. Between 9 and 12 months of age, an increase of nuclear huntingtin is observed. Homozygotes are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This mutant mouse strain represents a model that may be useful in studies of Huntington’s disease. This strain can serve as the control for the FVB-Tg(YAC128)53Hay/J (Stock No. 004938).

Development
A YAC containing a full-length human huntingtin gene was modified with a 133 CAG repeat expansion in exon 1 and a mutation in exon 13, at position 586, which encodes the caspase-6 cleavage site. The resulting construct (YAC353G6) was injected into FVB/NJ pronuclei. Founder line W7 (C6R7) was subsequently established. The mice were then backcrossed to FVB/NJ for 17 generations before arriving at The Jackson Laboratory.

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.
