Overview
Nomenclature: 129S6/SvEv-Stat1tm1Rds
- Contains a homozygous disruption of the Stat1 gene and complete lack of functional STAT1 proteins
- The JAK-STAT signaling pathway has been implicated in mediating biologic responses induced by many cytokines
- Homozygous mice develop normally
- Deficient immune cell response to alpha(α) and gamma(γ) interferons
- Extreme susceptibility to infections by microbial pathogens and viruses
- Could be used as sentinel animals for evaluating the health status of a mouse colony
- Accelerated and amplified development of chemically-induced and spontaneous tumors
- Useful in determining the role of a variety of cytokines in immune responses, the role of STAT1 protein in mediating interferon-dependent responses, and the roles of tumor cells and immune cells in mediating tumor cell destruction
Origin
The Stat1 mouse was developed in the laboratory of Robert Schreiber at the Washington University School of Medicine. The model was created by targeting the Stat1 gene in GS-1 ES cells and injecting the targeted cells into blastocysts. Heterozygotes for the mutation were produced from the chimeras and intercrossed to generate homozygotes. Taconic received stock in 1997. The mice were embryo transfer derived. The original Stat1 model (000679-M) differed from the Taconic 129S6 at two biochemical loci, Pgm1 and Gpi1. In January 2002, the original Stat1 line was backcrossed to the Taconic 129S6/SvEvTac, and animals were selected to match the Pgm1c and Gpi1b alleles of the 129S6. The selected heterozygotes were intercrossed to homozygosity. The line is maintained through incrossing of homozygous mice. This improvement makes the 129S6/SvEvTac a more perfectly matched control for the Stat1 model.

Packing Practices
Taconic standard practice is to recombine animals of different home cages and/or ages from a single model and sex during packing, except in specific cases where Taconic's animal welfare policy prohibits recombination due to aggression or other concerns. When an order is fulfilled with animals from more than one week of birth, this standard practice results in animals from a range of birth weeks packed together in a single TTC. When an order is fulfilled with animals from genotyped models, this standard practice results in animals from different home cages packed together in a single TTC.
Customers who wish to keep animals from different weeks of birth separated should place orders with the special instruction "Divide and label by age." Note that this special request can result in increased costs for additional Taconic Transit Cages, dividers and/or freight charges.
Taconic discourages other types of custom packing requests as they can have a negative impact on animal welfare. Learn more.
