Overview

Also Known As:D1Lac, DBA1 Lac

DBA/1LacJ mice have been widely used in studies of collagen-induced arthritis, although recent in-house studies suggest that the response to collagen induction in the DBA/1LacJ strain is not as robust as indicated by earlier studies. DBA substrains of mice, derived from DBA which is the oldest inbred strain of mice, have been widely used in many areas of research including age-related hearing loss.

Important Note

This strain is homozygous for Cdh23^ahl, the age related hearing loss 1 mutation, which on this background results in progressive hearing loss with onset after 10 months of age.

Detailed Description

Historical reports indicate DBA/1J and DBA/1LacJ mice immunized with type II collagen develop a severe polyarthritis mediated by an autoimmune response. Recent in-house studies suggest that the response to collagen induction in the DBA/1LacJ strain is not as robust as indicated by earlier studies. Arthritis models such as B10.RIII-H2^r H2-T18^b/(71NS)SnJ (Stock No. 000457) and BUB/BnJ (Stock No. 000653) can be used as alternatives to DBA/1LacJ. Similar to the human condition, mice with collagen-induced arthritis display synovitis and erosions of cartilage and bone. In addition, susceptibility in both humans and mice is linked to the expression of specific MHC class II molecules. DBA/1 mice show a low susceptibility to developing atherosclerotic aortic lesions (20 to 350 um2 atherosclerotic aortic lesions/aortic cross-section) following 14 weeks on an atherogenic diet (1.25% cholesterol, 0.5% cholic acid and 15% fat).

Development

The DBA inbred strain is the oldest of all inbred strains of mice. Dr. CC Little began inbreeding in 1909 from a mouse colony segregating for coat color. During 1929 and 1930 crosses were made among substrains, and several new substrains were established including DBA/1 and DBA/2. DBA/1 and DBA/2 differ at a large number of loci (including the MHC H2 haplotype) which most likely results from residual heterozygosity in the strain when the substrains were separated.

In 1955, mice were transfered from The Jackson Laboratory to Laboratory Animal Center (Lac), Carshalton, UK. In 1981, embryos from the Frozen Embryo Bank at Lac were sent to Les at The Jackson Laboratory.

Cdh23^ahl

Allele Symbol: Cdh23^ahl

Allele Name	age related hearing loss 1
Allele Type	Spontaneous
Allele Synonym(s)	Cdh23^753A; mdfw
Gene Symbol and Name	Cdh23, cadherin 23 (otocadherin)
Gene Synonym(s)
Strain of Origin	multiple strains
Chromosome	10
Molecular Note	Genetic complementation tests have shown allelism between the mdfw (modifier of deaf waddler) locus and the ahl locus. Further analysis has shown this is caused by a G to A transition at coding nucleotide position 753 of Cdh23 (SNP rs257098870). This hypomorphic allele changes splice donor site G-GT to A-GT, causing frame skipping of exon 7. This is predicted to delete part of the 2nd and 3rd ectodomains and cause reduced message stability. Twenty-seven strains classified with ahl and carrying the 753A allele include: CD-1, RBF/DnJ, PL/J, AKR/J, RF/J, BALB/cBy, A/WySnJ, P/J, SENCARA/PtJ, DBA/1J, ALS/LtJ, C58/J, C57BLKS/J, 129P1/ReJ, C57BR/cd, SKH2/J, BUB/Bn, MA/MyJ, LP/J, 129X1/SvJ, NOR/LtJ, A/J, C57BL/6, NOD/LtJ, DBA/2J, ALR/LtJ, C57L/J. Strains classified with ahl that DO NOT carry this mutation include: 129S1/SvImJ, C3H/HeSnJ, I/LnJ, YBR/Ei, MRL/MpJ.

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