“…This result strongly supports the idea that both European and Oriental mice were involved in the history of laboratory mice. Indeed, several observations suggest the contribution of Oriental mice to the establishment of laboratory mice: (1) Genes such as HbbP in AU/Ssl [12,13,23,24,271, Akv in AKR [3,28], Fv-4 in FRG (G mice) [19,29], and C3-Ia in NC and NBR are common in Asiatic mice but rare in European mice. (2) Most inbred strains show strain-specific chromosomal distributions of faintly staining C-bands, while wild M. m. domesticus rarely has such faint C-banded chromosomes.…”

“…On the other hand, a number of biochemical loci controlled by nuclear genes have mostly shown alleles of the MUS type [11]. Subsequently, based on the whole genome sequence of C57BL/6, 79,000 SNPs were prepared to survey the genomic structures of various CIS and WIS strains [27].…”

Unique Inbred Strain MSM/Ms Established from the Japanese Wild Mouse

Most laboratory mice belong to a species of house mouse, Mus musculus. So far, at least three subspecies groups have been recognized; domesticus subspecies group (DOM) distributed in western Europe, musculus subspecies group (MUS) distributed in eastern Europe and northeast Asia, and castaneus subspecies group (CAS) found in southwest and southeast Asia including southern China. These subspecies are estimated to have branched off roughly one million years ago. Genetic comparison between subspecies' groups and common inbred strains (CIS) have revealed that the genetic background of CIS is derived mainly from DOM. This shows the importance of non-DOM wild mice as valuable genetic resources. We started to establish our unique strain, MSM/Ms, from MUS in Japan in 1978. In the beginning, we kept wild mice trapped in Mishima in large plastic buckets. In 1979, breeding by sister-brother mating started. The MSM/Ms inbred strain was established in 1986 and 21 years later it reached F 100 . During breeding, no significant fluctuations in litter size and sex ratios have been observed. Extensive genetic analyses of chromosome C-banding pattern, biochemical markers and microsatellite DNA (MIT) markers of this strain have demonstrated the characteristics of MUS. A phylogenetic tree constructed from MIT markers has confirmed the MUS nature of MSM strain. Taken together with its genetic remoteness from CIS, MSM appears to maintain many valuable alleles for investigation of biological functions and diseases. Some of these alleles have avoided selection during breeding as either fancy mice or laboratory mice. The MSM-specific genetic traits discovered to date are discussed.

“…Recent genetic studies have demonstrated that modern subspecies of Mus musculus, such as M. m. domesticus, M. m. musculus, and M. m. castaneus, diverged from ancestral mice at least 1 million years ago (Moriwaki et al 1979, Minezawa et al 1981, Sage 1981, Yonekawa et al 1981, Ferris et al 1983, Bonhomme et al 1984. The Japanese wild mouse, M. m. molossinus, is now considered to be a hybrid between M. m. musculus and M. m. castaneus from data on the polymorphism of mtDNA and other genetic considerations (Suzuki et al 1986, Yonekawa et al 1988.…”

New evidence fortrans-species evolution of theH-2 class I polymorphism

et al. 1989

A serological survey using alloantisera specific for the H-2 class I antigens in Japanese wild mice. Mus musculus molossinus, revealed a high frequency of the H-2Kf antigen. This antigen has also been found in European wild mice, M. m. domesticus and M. m. musculus. In this survey, the H-2Kf antigen was characterized through the use of ten newly isolated monoclonal antibodies raised against cells of a Japanese wild mouse, and by Southern blot analysis using an H-2K locus-specific probe which hybridizes with the 3' end of the gene. The serologically identified H-2Kf antigens revealed several minor variations in reactivities to the monoclonal antibodies. However, all the antigens examined could be clearly separated into two types with respect to the restriction fragment length polymorphism (RFLP) pattern. The first type, found together with a single, characteristic RFLP pattern, was always associated with the presence of reactivity to one particular monoclonal antibody MS54. The second type, found to represent different RFLP patterns, is associated with the absence of reactivity to MS54. This concordance between the presence of an antigenic determinant and a particular RFLP was observed not only within Mus musculus subspecies but also in a different species: M. spretus, carrying the same antigenic determinant, gave an identical RFLP to that of the other MS54-positive Mus musculus subspecies. The data suggest that the antigenic determinant specific for MS54 is an ancient polymorphic structure which has survived the long period of diversification of Mus species (approximately 2-3 million years) without alteration, and is associated with a stable DNA structure at the 3' end of the H-2K gene.
