Availability: Cryopreserved as heterozygous embryos
Zygosity genotype: Homozygous as live colony
Developed in collaboration with The Michael J. Fox Foundation, this model contains a deletion of the Park7 (Protein deglycase DJ-1) gene, encoding for the protein DJ-1. Mutations in DJ-1 have been linked to autosomal recessive early-onset Parkinson's disease (PD), making this model useful to further understand the role of DJ-1 in PD.
In humans, loss of function of Park7 leads to a form of early-onset Parkinson's disease. This occurs due to the role Park7 plays in protecting neurons from oxidative stress and cell death, making this an ideal model for the study of Parkinson's disease.
The Park7 DJ-1 KO rat model was originally created at SAGE Labs, Inc. in St. Louis, MO and distributed out of the Boyertown, PA facility. The line continues to be maintained through the original SAGE Labs animal inventory acquired by Envigo, then Envigo was acquired by Inotiv in 2021.
