Project description:To evaluate the roles of DUOX2 in flagellin- induced inflammatory response in mouse nasal mucosa. Wild type (Duox2+/+) and Duox2 knockout (Duox2-/-) mice were stimulated with 1 M-NM-<g/ml of flagellin for 4h. 422 genes (> 2 fold) were up-regulated in nasal mucosa of Duox2+/+ that was treated with flagellin and the full list of genes is presented in Supplemental Table II. These genes included the following defense- and immune response-related genes : Cytokine/chemokine-related genes (CCL20, CCR2, CCR5, CXCL2, CXCL5, CXCL9, CXCL16, IL18RAP, TNFAIP2, IL1B EAR2, FPR1), Granulocyte-related genes (IL8RB, MPO, PRG2, PPBP, PRG3), interferon-related genes (IFITM6, IFI47), macrophage related genes (IL1B, S100A9), and T-cell mediated immune response related genes (H2-Q6, IL1F9). In addition, signal transduction (PPBP, OLFR60, P2RY10) and cell adhesion (SELL, SELP, ICAM1, DSG1A, DSG3, VCAM1) related genes were also increased by flagellin treatment. These genes were selected based on the biological processes and molecular functions of their gene ontology. However, the increase of inflammation and immune response related genes by flagellin treatment were diminished in the nasal mucosa of the Duox2-/- mice compared with that of Duox2+/+ mice. Wild type (Duox2+/+) and Duox2 knockout (Duox2-/-) mice received either PBS (control) or flagellin (5 ug/ml) intranasally for 4h.

Project description:Purpose: Ipratropium bromide (IB) is able to ameliorate symptoms of allergic rhinitis (AR) by neuroimmunologic mechanism. We intended to explorer whether IB induced effect through modulating specific alteration of miRNA profiling or not. Methods: Nasal sRNAs (miRNAs) profiles of control mice and OVA-induced AR mice that were pre-treated with IB or normal saline before intranasal OVA challenge for 2 or 4 weeks were generated by high-throughput sequencing using Illumina Hiseq 2000.Raw data for sRNA (miRNA) profiles were processed to obtain corresponding clean data which were mapped to reference sequence(mm10) by TopHat(v2.0.9).The expression levels for these resulting mapped miRNAs were estimated by TPM (transcript per million),afterwards, the differentially expressed miRNAs were identified, and the candidate allergic-related miRNAs were further determined by RT-qPCR. Results: Using an optimized data analysis workflow,our data showed that in nasal mucosa of allergic mice with ipratropium bromide (IB) treatment 87 miRNAs are differentially expressed whereas in the nasal mucosa of non-allergic mice 113 miRNAs are differentially expressed, when compared with allergic mice treated with normal saline.IB treatment significantly up-regulated the levels of mmu-miR-124-3p/5p, -133b-5p, -133a-3p/5p, -384-3p, -181a-5p, -378a-5p, -3071-5p. RT-qPCR data further validated these miRNAs expression. Conclusions: Our study represents the detailed analysis of nasal mucosa miRNAs profiles of OVA-induced allergic mice treated with IB, generated by RNA-seq technology. Moreover, IB treatment orchestrated expression of allergic immune-related miRNAs of nasal mucosa in allergic mice, which may associate with ameliorated nasal allergic symptoms

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

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:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility. Gene expression was measured in whole testis from males aged 62-86 days. Samples include 190 first generation lab-bred male offspring of wild-caught mice from the Mus musculus musculus - M. m. domesticus hybrid zone.
