Detailed Description

Mice homozygous for the Nfkb1^tm1Bal targeted mutation are viable and fertile. Homozygous mutant mice exhibit defective B cell responses, defective responses to infection, and also defects in basal and specific antibody production.

Development

Exon 6 of the Nfkb1 gene was disrupted by insertion of a vector containing the neo resistance gene. The construct was electroporated into 129P2/OlaHsd-derived E14 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts. The resulting chimeric animals were bred to crossed to C57BL/6J.

General Note	Effect of reconstitution with Nfkb1^tm1Bal homozygous hematopoietic cells on atherogenesis in atherosclerosis prone mice To assess the role of NFKB1 in atherogenesis, mice homozygous for a mutation of the low density lipoprotein receptor (Ldlr^tm1Her) were lethally irradiated and transplanted with bone marrow from Nfkb1^tm1Bal homozygous mice and 4 weeks later placed on a high-fat diet for 10 weeks. Aortic root lesion area of mice with NFKB1-deficient hematopoietic cells was 41% smaller than in control mice. Whereas control lesions contained primarily large foam cells, lesions of mice reconstituted with NFKB1-deficient bone marrow contained large numbers of small, inflammatory cells and very few foam cells. 3-fold as many cells attached to the lesion cap in transplanted mice. Most cells in control lesions were macrophages, while in transplanted mice there was a preponderance of T and B lymphocytes. Macrophages induced to differentiate in culture from NFKB1-deficient bone marrow exhibited differences compared to control macrophages in the secretion patterns of several cytokines following lipopolysaccharide (LPS) stimulation. Whereas control macrophages expressed high levels of scavenger receptor class A (SR-A) in response to LPS, this response was greatly attenuated in mice with NFKB1-deficient hematopoietic systems; uptake of oxidized low density lipoprotein (oxLDL) was similarly diminished, although neither parameter differed between transplant and control macrophages in the absence of stimulation. J:87639
Molecular Note	Insertion of a PGK-neomycin resistance cassette into exon 6 disrupted the gene. Exon 6 encodes the p105 precursor of the p50 subunit of the encoded transcription factor. The authors predict that this allele produces a truncated polypeptide that cannot bind with DNA, or dimerize with itself or other kappaB binding motifs.

Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We 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.

The Jackson Laboratory's Genotype Promise

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.
