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:We have shown that the expression of the endoplasmic reticulum stress sensor Creb3l1 increases in magnocellular neurones (MCNs) in the rat hypothalamus in response to increased physiological demands for protein synthesis. Here we adopted a multiomic strategy to investigate specific roles of Creb3l1 in MCN homeostasis. We first performed chromatin immunoprecipitation followed by genome sequencing (ChIP-seq) to identify Creb3l1 genomic targets in the water deprived MCN enriched hypothalamic preparation. We then compared ChIP-seq gene targets with water deprived and Creb3l1 knockdown supraoptic nucleus RNA sequencing transcriptome datasets. This has provided an integrated signalling-gene regulation network for this transcription factor illuminating changes to cell pathways and function, an approach that has led us to understand the physiological changes that occur in MCNs to cope with excessive protein demands.

Project description:The aims of our study were: 1) to elucidate physiological responses in three Miscanthus species and newly bred triploid hybrid in three water stress treatment conditions 2) utilise the induced physiological conditions for an in-depth transcriptome study on the molecular basis of water stress in Miscanthus spp.
Project description:Regardless of its anatomical site, adipose tissue shares a common energy-storage role but exhibits distinctive properties. Exploring the cellular and molecular heterogeneity of white adipose tissue (WAT) is crucial for comprehending its function and properties. In this study, we employed Single nucleus RNA sequencing (snRNA-seq) to test five representative depots including inguinal, epididymal, mesenteric, perirenal, and pericardial adipose tissues in mice under physiological conditions. By analyzing the contents of main cell categories and gene profiles of various depots, we identified their distinctive physiological properties.
