Type JAX® GEMM® Strain - Mutant Strain
Type JAX® GEMM® Strain - Targeted Mutation
Mating SystemHomozygote x Homozygote         (Female x Male)
Specieslaboratory mouse
Donating Investigator Richard Cummings,   University of Oklahoma
GenerationN5+N1F1 (25-APR-08)

Strain Description
Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical abnormalities. No gene product (mRNA or protein) is detected by in situ hybridization of dorsal root ganglia and facial motorneuron nucleus and Western blot analysis of adult muscle tissue. Neonate mice homozygous for the mutation have abnormal axon targeting to the caudal region of the olfactory bulb. Mutant mice have fewer neural progenitor cells in the subventricular zone of the forebrain, although the number of apoptotic cells are not affected. Homozygotes exhibit hypoalgesia with a diminished nocifensive withdraw response to thermal testing. Immunohistological analysis of dorsal root ganglia from homozygotes reveals abnormal proportions of axon subpopulations and a larger number of myelinated axons. Mutant mice have a longer recovery of motorneuron function after experimental nerve injury. This mutant mouse strain represents a model that may be useful in studies of pain reception, motorneuron regeneration, axonal growth and guidance and development of the nervous system.

This strain was transferred from the collection of the Consortium for Functional Glycomics.

Strain Development
A targeting vector containing neomycin resistance and herpes simplex virus thymidine kinase genes was used to disrupt 1.0kb of sequence that includes exon 2. The construct was electroporated into 129S6/SvEvTac derived CCE embryonic stem (ES) cells. Correctly targeted ES cells were injected into outbred MF-1 blastocysts. The resulting chimeric male animals were crossed to outbred MF-1 female mice. Heterozygotes were crossed to generate homozygotes. The mice were then bred to mice homozygous for a targeted mutation of Lgals3. The double mutant strain was then backcrossed to C57BL/6 for 5 generations. Upon arrival at The Jackson Laboratory, the second allele was removed by selective breeding. These mice carry only the Lgals1tm1Rob allele.

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.
