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 μg/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.

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: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.
Project description:To explore the impact of nasal commensal viruses on the onset and progression of allergic rhinitis, We used single cell RNA sequencing (scRNA-seq) to analyze the diversity of CD45+ cells in the nasal mucosa of control and AR mice treated with Vehicle or Ribavirin.
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.
