Abstract
In the present paper, the existence and location of the type series of the Japanese dancing mouse or waltzer, Muswagneri variety rotans Droogleever Fortuyn, 1912, are established, and a lectotype is designated. Available type specimens are measured, and some morphological parameters, sex, and general condition of the specimens are recorded. A literature survey was conducted, and an attempt is made to clarify the position of M.wagneri variety rotans in the taxonomy of Mus. A genetic analysis suggests that the type series of the Japanese dancing mouse represent a crossbred, or derivation of a crossbred, between the original Japanese dancing mouse of Musmusculusmolossinus Temminck 1844 origin and European fancy or laboratory mice of Musmusculusdomesticus Schwarz & Schwarz, 1943 origin. Much of their genome was replaced and occupied by Musmusculusdomesticus type genome, probably through extensive breeding with European mice.

Abstract
We analyzed 196 haplotype sequences from a gene-rich region (250 kb) that includes Mc1r, a gene involved in coat color regulation, to gain insight into the evolution of coat color variation in subspecies of the house mouse Mus musculus. Phylogenetic networks revealed haplotype groups from the major subspecies of M. m. castaneus (CAS), M. m. domesticus (DOM), and M. m. musculus (MUS). Using haplotype sequences assigned to each of CAS and MUS through phylogenetic analysis, we proposed migration routes associated with prehistoric humans from west to east across Eurasia. Comparing nucleotide diversity among subspecies-specific haplotypes in different geographic areas showed a marked reduction during migration, particularly in MUS-derived haplotypes from Korea and Japan, suggesting intensive population bottlenecks during migration. We found that a C>T polymorphism at site 302 (c.302C>T) in the Mc1r coding region correlated with a darkening of dorsal fur color in both CAS and MUS. However, C/C homozygous mice in MUS showed marked variation in lightness, indicating the possibility of another genetic determinant that affects the lightness of dorsal fur color. Detailed sequence comparisons of haplotypes revealed that short fragments assigned to DOM were embedded in CAS-assigned fragments, indicating ancient introgression between subspecies. The estimated age of c.302C>T also supports the hypothesis that genetic interaction between subspecies occurred in ancient times. This suggests that the genome of M. musculus evolved through gene flow between subspecies over an extended period before the movement of the species in conjunction with prehistoric humans.

Two Loci Contribute to Age-Related Hearing Loss Resistance in the Japanese Wild-Derived Inbred MSM/Ms Mice. Biomedicines 2022; 10:biomedicines10092221.

Abstract
An MSM/Ms strain was established using Japanese wild mice, which exhibit resistance to several phenotypes associated with aging, such as obesity, inflammation, and tumorigenesis, compared to common inbred mouse strains. MSM/Ms strain is resistant to age-related hearing loss, and their auditory abilities are sustained for long durations. The age-related hearing loss 3 (ahl3) locus contributes to age-related hearing in MSM/Ms strain. We generated ahl3 congenic strains by transferring a genomic region on chromosome 17 from MSM/Ms mice into C57BL/6J mice. Although C57BL/6J mice develop age-related hearing loss because of the ahl allele of the cadherin 23 gene, the development of middle- to high-frequency hearing loss was significantly delayed in an ahl3 congenic strain. Moreover, the novel age-related hearing loss 10 (ahl10) locus associated with age-related hearing resistance in MSM/Ms strain was mapped to chromosome 12. Although the resistance effects in ahl10 congenic strain were slightly weaker than those in ahl3 congenic strain, slow progression of age-related hearing loss was confirmed in ahl10 congenic strain despite harboring the ahl allele of cadherin 23. These results suggest that causative genes and polymorphisms of the ahl3 and ahl10 loci are important targets for the prevention and treatment of age-related hearing loss.
