Orders by weight:
- Carries a genomic deletion of a region of mouse chromosome 7 that corresponds to human chromosome region 15q13.3.
- In humans, hemizygous deletion of chromosome 15q13.3 confers high risk of schizophrenia, autism, and epilepsy in human patients
- Schizophrenia related phenotype: EEG characterization revealed auditory processing deficits similar to those observed in schizophrenia. They have impaired long-term spatial reference memory and decreased performance in the novel object recognition task.
- Epilepsy related phenotype: Human 15q13.3 deletion mice show changes in neuronal excitability in acute seizure assays, with increased propensity to develop myoclonic and absence-line seizures; decreased propentisty for clonic and tonic seizures.
- Useful as a model of schizophrenia-like pathology and studying the underlying biology of schizophrenia, epilepsy, and other neural circuit defects associated with 15q13.3 deletion in humans
Taconic cannot accept orders by weight for this model. Please note that shipments may contain animals with a larger weight variation.
Origin: The Df(h15q13)/+ mouse line was developed for H. Lundbeck A/S at Taconic Biosciences GmbH (Cologne, Germany). Two targeting vectors were generated using bacterial artificial chromosome clones from the C57BL/6J RPCI-23 library and transfected into TaconicArtemis C57BL/6N Tac embryonic stem cell line. The first vector introduced a loxP site upstream of the Chrna7 gene. The second vector introduced a loxP site downstream of the Fan1 gene. Homologous recombinant clones were isolated and the 1.28 megabase region on mouse chromosome 7 between the loxP sites was removed using in vitro Cre-mediated recombination. Hemizygotic embryonic stem cells were injected into blastocysts isolated from impregnated BALB/c female mice and transferred to pseudopregnant NMRI female mice. Chimeric male pups were selected by coat color and mated with wild-type C57BL/6 female mice. Finally, a chimera with germline transmission was selected for expansion breeding. The colony was maintained by mating wild-type C57BL/6N mice with hemizygous Df(h15q13)/+ mice.
