Project description:ABSTRACT: The cactus mouse (Peromyscus eremicus) is a desert-specialized rodent that experiences both chronic and acute dehydration in the Southwestern United States. Our previous research has generated substantial transcriptomic data on P. eremicus kidneys, testes, epididymis, and vas deferens in individuals exposed to hydrated and dehydrated conditions; however, the study described here is the first to describe a seminal vesicle proteome for this species. We have produced a seminal vesicle proteome from P. eremicus with free access to water and mice that were acutely dehydrated to generate a dataset that is comprehensive for both alternative water-availability states experienced by this species. We have also provided gene ontologies for this proteome using PANTHER. This proteome will provide a crucial resource for future studies characterizing the genetic and proteomic responses of reproductive tissues to drought in this rodent. Furthermore, an enhanced understanding of survival and reproductive responses (and adaptations) to dehydration is particularly relevant to clinical work aiming to minimize adverse human impacts as climate change continues to increase the incidence of drought.

Project description:Exploring the physiological responses and multi-tissue gene expression in water deprived Peromyscus eremicus
Project description:Whole transcriptome RNA sequencing in primary fibroblasts of outbred Peromyscus maniculatus was generated to explore the degree of coordination in gene expression.
Project description:We used RNA-seq to compare transcriptional profiles from the embryonic tails from E12.5–E15.5 Peromyscus maniculatus. Samples are from two ecotypes, forest (P.m.nubiterrae) and prairie (P.m.bairdii) with different numbers of caudal vertebrae.
Project description:Genetic variation is known to contribute to the variation of animal social behavior, but the molecular mechanisms that lead to behavioral differences are still not fully understood. Here, we investigate the cellular evolution of the hypothalamic medial preoptic area (MPOA), a brain region that plays a critical role in social behavior, across two sister species of deer mice (Peromyscus maniculatus and P. polionotus) with divergent social systems. These two species exhibit large differences in mating and parental care behavior across species and sex. Using single-nucleus RNA-sequencing, we build a molecular atlas of the MPOA for males and females of both Peromyscus species.
Project description:We used RNA-seq to estimate allelic expression bias in the embryonic tails of E12.5 and E14.5 Peromyscus maniculatus nubiterrae x bairdii. Samples are from F1 hybrids between forest (P.m.nubiterrae) and prairie (P.m.bairdii) with different numbers of caudal vertebrae.
