Mice that are homozygous for this Bid (BH3 interacting domain death agonist) targeted mutation resistant to hypoxia-ischemia (HI) injury, experimentally induced apoptosis, and oxygen toxicity under hyperoxic conditions. This mutant mouse strain may be useful in studies of mitochondiral activation in apoptosis, and ischemic cell injury and death.

Targeted (Null/Knockout) | Bid | BH3 interacting domain death agonist |
Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No gene product (protein) is detected by Western blot analysis of spleen and thymus tissue. Most homozygotes survive injection of anti-Fas antibodies while wildtype mice succumb to acute liver failure within hours. Mutant mice are resistant to hypoxia-ischemia (HI) injury, experimentally induced apoptosis, and oxygen toxicity under hyperoxic conditions. Homozygotes exhibit reduced lysosome permeability and diminished reactive oxygen species generation. Isolated neurons are resistant to oxygen/glucose deprivation induced cell death.
This mutant mouse strain may be useful in studies of mitochondiral activation in apoptosis, and ischemic cell injury and death.
A targeting vector containing a PGK-neo cassette was used to disrupt exons 1 and 2 and part of exon 3. The construct was electroporated into 129X1/SvJ derived RW-4 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. The resulting chimeric animals were crossed to C57BL/6 mice, and then backcrossed to C57BL/6 for 12 generations before arriving at The Jackson Laboratory.

Strain of Origin | 129X1/SvJ |
Chromosome | 6 |
Molecular Note | A 4.2 kb genomic fragment containing exons 1, 2 and part of 3 was replaced with a neomycin selection cassette inserted in reverse transcriptional orientation to the gene. The deleted sequences encode the BH3 domain of the protein. Western blot analysis on spleen and thymus samples derived from homozygous mice demonstrated that no detectable protein is produced from this allele. |

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
