Generation Definitions
Donating Investigator Shizuo Akira,   Osaka University

A neo cassette replaces exons 2-5 of the lipocalin 2 (Lcn2) gene, abolishing gene expression. LCN2 is an iron-trafficking protein involved in apoptosis and the regulation of the innate immune systems response to bacterial growth and infection. Toll-like receptors on innate immune cells stimulate the production and secretion of LCN2 upon bacterial infection. LCN2 limits bacterial growth by iron sequestration, which is required by bacteria in order to replicate. Homozygous LCN2-deficient mice are viable and fertile and should be housed in a specific pathogen free (SPF) facility. Escherichia coli challenge causes an increase in bacterial burden in the liver and spleen along with physical signs of sepsis such as lethargy, hunched posture, and ruffled fur. E Coli infection caused no difference in leukocyte numbers, neutrophil infiltration, or tissue iron distribution. Also, after induction of accelerated nephrotoxic serum nephritis (NTS), LCN2 KO mice exhibit more glomerular damage with increased proteinuria and interstitial leukocyte accumulation than wildtype mice.

A targeting vector was designed to replace exons 2-5 of the lipocalin 2 (Lcn2) gene with a neomycin resistance (neo) cassette. The construct was electroporated into 129P2/OlaHsd-derived E14.1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts and the resulting chimeric males were bred to C57BL/6J females. These mice were backcrossed for at least 10 generations to C57BL/6J mice. Upon arrival at The Jackson Laboratory, mice were bred to C57BL/6J (Stock No. 000664) for at least one generation to establish the colony.

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.
