This strain does not carry mouse mammary tumor virus (MMTV). See JAX Notes, May 2000, #480. This strain is also homozygous for the retinal degeneration allele Pde6brd1. See article "Genetic Background Effects: Can Your Mice See?", JAX Notes Spring 2002, No. 485.Strain Description
C3H/HeOuJ mice are used as a general purpose strain in a wide variety of research areas including cancer and sensorineural, research. C3H/HeOuJ mice and all other C3H substrains at The Jackson Laboratory are homozygous for the retinal degeneration 1 mutation (Pde6brd1), causing blindness by weaning age. There is also a high incidence of hepatomas in C3H mice (reportedly 72-91% in males at 14 months, 59% in virgin females, 30-38% in breeding females). Despite the lack of exogenous mouse mammary tumor virus (MMTV), virgin and breeding females may still develop some mammary tumors later in life.Strain Development
The C3H parent strain was developed by LC Strong in 1920 from a cross of a Bagg albino female with a DBA male followed by selection for high incidence of mammary tumors. This high incidence resulted from exogenous mouse mammary tumor virus (MMTV) transmitted through the mother's milk. The Jackson Laboratory maintains four C3H substrains, C3H/HeJ (Stock No. 000659), C3H/HeOuJ (Stock No. 000635), C3HeB/FeJ (Stock No. 000658) and C3H/HeSnJ (Stock No. 000661) that are now free of exogenous MMTV. C3H/HeJ and C3H/HeOuJ mice previously carried MMTV but were rederived in 1999 during planned efforts to increase the overall health status of the mice and the virus not reintroduced. C3H/HeJ and C3H/HeOuJ substrains were separated in 1952 and are genetically very similar. However, a spontaneous mutation occurred in C3H/HeJ sometime between 1960 and 1968 at lipopolysaccharide response locus (mutation in toll-like receptor 4 gene, Tlr4lps) making C3H/HeJ mice endotoxin resistant while the other three C3H strains are endotoxin sensitive.

| General Note |
Pde6brd1, retinal degeneration 1, recessive. Formerly r, rd, rd1. A mutation causing retinal degeneration described by Bruckner (J:25576) and by Tansley (J:15333) in various stocks was later found to be present in many inbred strains (J:114). Keeler (J:5007) thought it to be identical with the rodless retina mutation he had described in 1924 (J:24999); the identity has recently been proven by analyses of DNA from Keeler's original slides (J:15231). Homozygotes are fully viable and fertile.Eyes develop normally up to 7 to 10 days after birth. At this stage the outer segment of the rod cell has begun to form, and in wild type mice it elongates rapidly during the 10th to 15th days. In Pde6brd1/Pde6brd1 mice the nascent outer segments and the rod cells degenerate rapidly so that by 15 days there is only a thin layer of rod cells left, and they have disappeared completely by 35 days (J:5250, J:5708). The inner nuclear layer and the retinal ganglion cells appear normal butmay show slight quantitative reduction (J:5812, J:5292). Although the eyes of Pde6brd1 homozygotes are devoid of normal rods, the mice have some visual capacity (J:5980). About 3% of cones among the visual cells degenerate at a much slower rate than do rods, so that a few cones are still present at 18 months (J:5988). The surviving cones are postulated (J:25157) as the light receptors required for the persistence of circadian responses to dawn and dusk in Pde6brd1 homozygotes past the sstage when rods have disappeared (J:29236). In fusion chimeras between wild type and Pde6brd1 homozygous embryos, the Pde6brd1 mutant acts in the photoreceptor cells rather than in the pigment epithelium of the retina (J:5708). Action within photoreceptor cells is also implied by the long term survival of wild type rod cells transplanted into Pde6brd1 homozygote retinas (J:20769). At a stage before degeneration can be seen, a deficiency of cGMP-PDE, andan excess of cGMP, appears in rod photoreceptor cells (J:5332). The rate of retinal degeneration in mutants doubly homozygous for two retinal degeneration mutations (Pde6brd1 and RdsRd2) is intermediate between those of the two homozygotes (J:12044). The double homozygote shows an intermediate level of mRNAs for the ß subunit of cGMP-PDE and for several other phototransduction related proteins, suggesting an interaction between Pde6brd1 and RdsRd2 (J:2579).

| Molecular Note | Two mutations have been identified in rd1 mice. A murine leukimia virus (Xmv-28) insertion in reverse orientation in intron 1 is found in all mouse strains with the rd1 phenotype. Further, a nonsense mutation (C to A transversion) in codon 347 that results in a truncation eliminating more than half of the predicted encoded protein, including the catalytic domain has also been identified in all rd1 strains of mice. A specific degradation of mutant transcript during or after pre-mRNA splicing is suggested. [MGI Ref ID J:11513] [MGI Ref ID J:4366] [MGI Ref ID J:51361] | ||

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.Ordering and Purchasing Information
