Strain Information
Type Coisogenic; Mutant Strain; Targeted Mutation; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Mating System Heterozygote x Heterozygote (Female x Male) 10-OCT-12 Species laboratory mouse Donating Investigator Nancy C. Andrews, Children's Hospital/HHMI Description
The divalent metal transporter DMT1, encoded by Slc11a2, is essential for iron and micronutrient uptake in the gut and other tissues. These mice possess loxP sites on either side of exons 6 through 8 of the targeted gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When these mutant mice are bred to mice that express Cre recombinase, resulting offspring will have exons 6 through 8 deleted in the cre-expressing tissues.When bred to a strain with Cre recombinase expression in hippocampal neurons, this mutant mouse strain may be useful in studies of the role of iron in neurodevelopment, neurobiology and neurodegenerative diseases.
Development
A targeting vector containing a floxed NEO-CD(cytidine deaminase) cassette was utilized in the construction of this mutant. This selection cassette was inserted downstream of exon 8 of the targeted gene, and another loxP site was inserted upstream of exon 6. The construct was electroporated into 129S4/SvJae derived J1 embryonic stem (ES) cells which were transiently transfected with a Cre recombinase vector to remove the selection cassette. ES cells that had successfully undergone Cre-mediated recombination and no longer retained the cassette but did retain the loxP-flanked exons 6-8 were injected in C57BL/6 blastocysts. The resulting chimeric animals were crossed to 129S6/SvEvTac mice, and then backcrossed to 129S6/SvEvTac for more than 10 generations.

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 Information
