These mitochondrial cyclophilin knockout mice may be useful in studying mitochondrial-driven cell death, as well as brain and cardiac injury.

Mitochondria isolated from the livers, hearts, and brains of homozygous targeted mutant mice are resistant to swelling and permeability transition in vitro. Hepatocytes and fibroblasts are largely protected from Ca2+-overload and oxidative stress-induced cell death. Mice are protected from ischaemia/reperfusion-induced cell death in vivo. This strain may be useful in studies of mitochondrial-driven cell death.
The first three coding exons were replaced with a neomycin resistance cassette. A 129-dervived emabryonic stem (ES) cell line was used to create the mutation. Chimeras were crossed to C57BL/6 and the strain was maintained on a mixed C57BL/6 and 129 genetic background by the donating laboratory.
|Allele Name||targeted mutation 1, Jeffery D Molkentin|

When maintained as a live colony, homozygotes or heterozygotes may be bred. Homozygotes are smaller than wildtype mice and are prone to obesity as they age.
When using the Ppif<sup>-</sup> mouse strain in a publication, please cite the originating article(s) and include JAX stock #009071 in your Materials and Methods section.

The average number of mice provided from recovery of our cryopreserved strains is 10. The total number of animals provided,
their gender and genotype will vary. We will fulfill your order by providing at least two pair of mice, at least one animal of
each pair carrying the mutation of interest. Please inquire if larger numbers of animals with specific genotype and genders
are needed. Animals typically ship between 10 and 14 weeks from the date of your order. If a second cryorecovery is needed in
order to provide the minimum number of animals, animals will ship within 25 weeks.
The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.
Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.
