Description
Mice homozygous for this ENU-induced F345I hypomorphic allele (Chaos3) are viable, fertile, and overtly indistinguishable from normal littermates. Homozygous, but not heterozygous, mice have slightly reduced wildtype protein levels in mouse embryonic fibroblasts (MEFs). Whereas Chaos3 heterozygotes show mildly elevated (2- to 5-fold) micronucleus frequencies compared with wildtype, homozygotes have an approximate 20-fold increase with over 7% of erythrocytes containing micronuclei. MEFs from homozygous mice exhibit mild defects (cell proliferation, S phase and G2/M populations), and are highly susceptible to chromosome breakage following treatment with the DNA replication inhibitor aphidicolin. On a congenic C3HeB/FeJ background, greater than 80% of homozygous females exhibit mammary adenocarcinomas with a mean latency of 12 months, while males have no tumor incidence. These Chaos3 mice provide a novel, non-transgenic model of breast cancer, and may be useful for studying of diagnostic pre-cancer cell markers, chromosomal instability and cell cycle checkpoint responses.

Development
Male C57BL/6J mice (Stock No. 000664) were treated with multidose N-ethyl-N-nitrosourea (ENU) and then bred to C3HeB/FeJ (Stock No. 000658). The resulting male pups were then bred to C3HeB/FeJ females to obtain second generation mice, which were subsequently intercrossed to obtain third generation mice. A mutagenesis screen was then performed to select mice for chromosome instability (as assessed by micronucleus levels in erythrocytes). One of these mutants in which the tendency to form micronuclei segregated in a monogenic, autosomal recessive manner was termed Chaos3 (or chromosome aberrations occurring spontaneously 3). Further studies revealed that Chaos3 is a hypomorphic allele of Mcm4, containing a T to A transversion at nucleotide 1033 of the coding region that defines an amino acid change from phenylalanine to isoleucine at residue 345 (F345I). These mice have been backcrossed to C3HeB/FeJ for at least 8 generations prior to arrival at The Jackson Laboratory.

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.
