Project description:DBA/2J (D2) and C57BL/6J mice (B6) were infected intra-nasally with 2x10^3 FFU of influenza A H1N1 (PR8) virus. Lungs were collected from mock-infected controls or at day 1,2,3,4 post infection. Expression data were obtained from three independent experiments. We infected a highly susceptible mouse strain (D2) and a resistant strain (B6) with PR8 and performed a genome-wide expression analysis. We found genes expressed in lung epithelium that were specifically down-regulated in D2 mice, whereas a cluster of genes on chromosome 3 was only down-regulated in B6. In both mouse strains, chemokines, cytokines and interferon-response genes were up-regulated, indicating that the main innate immune defense pathways were activated. However, many immune response genes were up-regulated in D2 much stronger than in B6, and several immune response genes were exclusively regulated in D2. Thus, susceptible D2 mice showed a hyper-inflammatory response. This response is similar to infections with highly pathogenic influenza virus and may serve as a paradigm for a hyper-inflammatory host response to influenza A virus.

Project description:To gain insight into the host cell types, cellular and molecular pathways possibly involved in the differential permissiveness to pulmonary replication of M. tuberculosis, we carried out transcript profiling studies on M. tuberculosis-infected lungs from congenic and parental strains. We were particularly interested in two groups of transcripts. The first group consists of transcripts which expression in the lung is regulated in response to M. tuberculosis infection (global response to infection), and that is obtained by comparing transcripts profiles of infected vs. uninfected lungs. The second group of transcripts is associated with increased resistance to M. tuberculosis infection of B6 and D2.B6-Chr7 mice. That list consists in the overlap between the lists commonly expressed in response to infection between resistant B6 and D2.B6-Chr7 but that show a significant difference in modulation when compared to infected susceptible D2.<br><br> In these experiments, B6, D2 as well as the D2.B6-Chr19, and D2.B6-Chr7 congenic lines were infected with M. tuberculosis and lungs were harvested at day 30 and day 70, and RNA was prepared. Three independent RNA samples from each group were converted to labeled cDNAs and hybridized to Affymetrix oligonucleotides arrays (Mouse Genome 430 2.0 array). Hybridization results were analyzed with the Genesifter analysis program to characterize changes in gene expression.

Project description:MPP2, MPP3 and CLP populations were isolated by fluorescence-activated cell sorting (FACS) from the BM of B6 mice based on the surface expression of VCAM1, FLT3 and IL7Ra within LSK population. On average 100K cells were analyzed for each population in 3 independent biological experiments. We generated sequence libraries from these low RNA inputs using the SMARTer Stranded RNA-Seq and sequenced at high depth of coverage to generate ~2x120 M reads per biological replicate.

Project description:Purpose: The goal of the present study is to provide an independent assessment of the retinal transcriptome signatures of the C57BL/6J (B6) and DBA/2J (D2) mice and to enhance existing microarray datasets for accurately defining the allelic differences in the BXD recombinant inbred strains. Methods: Retinas from both B6 and D2 mice (3 of each) were used for the RNA-seq analysis. Transcriptome features were examined for both strains. Differentially expressed genes between the 2 strains were identified and bioinformatic analysis was performed to analyze the transcriptome differences between B6 and D2 strains, including Gene ontology (GO) analysis, Phenotype and Reactome enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. The RNA-seq data were then directly compared with one of the microarray datasets (DoD Retina Normal Affy MoGene 2.0 ST RMA Gene Level Microarray Database) hosted on GeneNetwork (www.genenetwork.org). Results: RNA-seq provided an in-depth analysis of the transcriptome of the B6 and D2 retina with a total of more than 30,000,000 reads per sample. Over 70% of the reads were uniquely mapped, resulting in a total of 18,100 gene counts for all 6 samples. 1,665 genes were differentially expressed, with 858 of these more highly expressed in B6 and 807 more highly expressed in D2. Several molecular pathways were differentially active between the two strains, including the retinoic acid metabolic process, endoplasmic reticulum lumen, extracellular matrix organization, and PI3K-Akt signaling pathway. The most enriched KEGG pathways were the pentose and glucuronate interconversions pathway, the cytochrome P450 pathway, protein digestion and absorption pathway and the ECM-receptor interaction pathway. Each of these pathways had a more than 4-fold enrichment. The DoD normal retina microarray database provided expression profiling for 26,191 annotated transcripts for B6 mouse, D2 mouse and 53 BXD strains. A total of 13,793 genes in this microarray dataset were comparable to the RNA-seq dataset. For both B6 and D2, the RNA-seq data and microarray data were highly correlated with each other (Pearson's r = 0.780 for B6 and 0.784 for D2). Our results suggest that the microarray dataset can reliably detect differentially expressed genes between the B6 and D2 retinas, with a positive predictive value of 45.6%, and a negative predictive value of 93.6%. Examples of true positive and false positive genes are provided. Conclusions: Retinal transcriptome features of B6 and D2 mouse strains provide a useful reference for a better understanding of the mouse retina. Generally, the microarray database presented on GeneNetwork shows good agreement with the RNA-seq data, while we note that any allelic difference between B6 and D2 should be verified with the latter.

Project description:CD69 is a transmembrane protein expressed on the surface of activated leukocyte. The ligand for CD69 and the intracellular signaling pathway of this molecule are yet unknown. It is widely used as a marker of activated lymphocyte, but its function in immune system is not known. We used micro-array to define genes whose expression is regulated by activation antigene CD69. CD4 T cells were isolated from the spleen of wt B6 and CD69-deficient B6 mice and in vitro activated with anti-CD3/anti-CD28 coated beads. On one groupe of wt B6 cells, CD69 was activated using a anti-CD69 and secoundary antibody. RNA extraction and hybridization on Affymetrix microarrays was performed for wt B6, CD69-activated wt B6 and CD69-deficient B6 CD4 T cells.

Project description:We inflicted TBI to wildetype (wt) mice in order to establish whether the anti-inflammatory agent cyclophosphamide can be used therapeutically. Cyclophosphamide was found to regulate distinct inflammatory cells such as activated microglia separate from invading phagocytes and dendritic cells. Cyclophosphamide postinjury selectively reduces antigen-presenting dendritic cells. Findings show feasibility of drug development to interfere with brain inflammation. TBI was carried out in injured wt B6 mice for postinjury treatment with cyclophospamide i.p. using saline as a control substance for comparison with injured but untreated mice. Total RNA was prepared from injured cerebral neocortex after three days. RNA samples were also from uninjured wt mice as reference for hybridization on Affymetrix microarrays.
