Project description:Translational research is commonly performed in the C57B6/J mouse strain, chosen for its genetic homogeneity and phenotypic uniformity. Here, we evaluate the suitability of the white-footed deer mouse (Peromyscus leucopus) as a model organism for aging research, offering a comparative analysis against C57B6/J and diversity outbred (DO) Mus musculus strains. Our study includes comparisons of body composition, skeletal muscle function, and cardiovascular parameters, shedding light on potential applications and limitations of P. leucopus in aging studies. Notably, P. leucopus exhibits distinct body composition characteristics, emphasizing reduced muscle force exertion and a unique metabolism, particularly in fat mass. Cardiovascular assessments showed changes in arterial stiffness, challenging conventional assumptions and highlighting the need for a nuanced interpretation of aging-related phenotypes. Our study also highlights inherent challenges associated with maintaining and phenotyping P. leucopus cohorts. Behavioral considerations, including anxiety-induced responses during handling and phenotyping assessment, pose obstacles in acquiring meaningful data. Moreover, the unique anatomy of P. leucopus necessitates careful adaptation of protocols designed for Mus musculus. While showcasing potential benefits, further extensive analyses across broader age ranges and larger cohorts are necessary to establish the reliability of P. leucopus as a robust and translatable model for aging studies.

Project description:The prevalence of some autoimmune diseases (AID) is greater in females compared with males, notwithstanding that disease severity is often greater in males. The reason for this sexual dimorphism (SD) is unknown, but may reflect negative selection of Y chromosome (ChrY) bearing sperm during spermatogenesis or male fetuses early in the course of conception/pregnancy. Previously, we showed that the SD in experimental autoimmune encephalomyelitis (EAE) is associated with copy number variation (CNV) in ChrY multicopy genes. Here, we test the hypothesis that CNV in ChrY multicopy genes influences the paternal parent-of-origin effect on EAE susceptibility in female mice. We show that C57BL/6J consomic strains of mice possessing an identical ChrX and CNV in ChrY multicopy genes exhibit a female biased sex-ratio and sperm head abnormalities, consistent with X-Y intragenomic conflict arising from an imbalance in CNV between homologous ChrX:ChrY multicopy genes. These males also display paternal transmission of EAE to female offspring and differential loading of miRNAs within the sperm nucleus. These findings provide evidence for a genetic mechanism at the level of the male gamete that contributes to the SD in EAE and paternal parent-of-origin effects in female mice, raising the possibility that a similar mechanism may contribute to the SD in MS.
