Project description:Noroviruses have been widely recognized for their importance as causative agents of non-bacterial gastroenteritis. Mouse norovirus is the only representative of the norovirus genus, family Caliciviridae, able to grow in cell culture. The aim of this study is to describe the differences in the expression profiles of MNV-1 and mock-infected macrophages (RAW 264.7 cells), in order to better understand the response of the host cell to norovirus infection.

Project description:IFNg is a pro-inflammatory and pro-atherogenic cytokine that leads to macrophage activation. Adenosine has well-documented anti-inflammatory properties. We used microarrays to compare the global gene expression profile in mouse macrophages stimulated with IFNg alone and those cells treated with IFNg and adenosine. We determined that adenosine suppressed the expression of many IFNg-regulated pro-inflammatory cytokines, chemokines, and other pro-atherogenic genes. Keywords: treatment response RAW 264.7 cells were treated for 4 hours with either IFNg or IFNg plus adenosine. Following treatment, total RNA was extracted and treatment groups were pooled from 2 separate experiments for hybridization of Affymetrix microarrays.

Project description:Purpose: The goal of this study is to compare NGS-derived wild type and Hnrnpul1 knockout (Hnrnpul1-/-) RAW 264.7 cells transcriptomes with or without LPS stimulation. Methods: Sequancing was performed by Novogene China Co. Ltd. RNA profiles of wild type and Hnrnpul1-/- RAW 264.7 cells as well as LPS stimulated (10 h) wild type and Hnrnpul1-/- RAW 264.7 cells were generated by deep sequencing using Illumina Novaseq 6000. Index of the reference genome was built using Hisat2 v2.0.5 and paired-end clean reads were aligned to the reference genome using Hisat2 v2.0.5. featureCounts v1.5.0-p3 was used to count the reads numbers mapped to each gene. And then FPKM of each gene was calculated based on the length of the gene and reads count mapped to this gene. Method of TMM was used to normalize the readcount. Negative binomial distribution model was used to calculate the P value, and FDR was calculated by the method of Benjaminiand Hochberg. Results: Using an optimized data analysis workflow, we mapped about 40 million sequence reads per sample to the mouse genome (GRCm38/mm10). Comparing to wild type RAW 264.7 cells, 237 genes were up-regulated and 181 genes were down-regulated in Hnrnpul1-/- cells. At 10 h following LPS stimulation, 341 genes were up-regulated and 288 genes were down-regulated in Hnrnpul1-/- cells. Genes were pre-ranked according to log2FoldChange(KO/WT) followed by GSEA and 6 gene sets were significantly enriched. Significantly differential genes were undergone GO analysis (biological process) and biological process including cell-cell adhesion, positive regulation of cell activation and regulation of response to external stimulus were enriched. Conclusions: Lacking Hnrnpul1 promotes the expression of inflammatory cytokines in LPS stimulated RAW 264.7 cells.

Project description:Human peripheral blood mononuclear cells were cultured in presence of H37Ra strain at 37oC, 5%CO2. Cellular aggregates were collected at 24h, and RNA extracted and hybridized to Affymetrix microarrays (HG-U133). Raw data from microarray experiments was analyzed with dCHIP and SAM programs to determine the significance of changes at the biological context. PBMCs were exposed in triplicate to H37Ra strain. PBMCs from the same donor were cultured in triplicate at the same conditions than treated samples. RNA was extracted from each sample and hybridized to Affymetrix Human arrays.

Project description:We have searched genome-wide binding sites of mouse group V secretory phospholipase A2 (gV sPLA2) in Raw 264.7 cells. Since we previously had technical problems in immunoblotting analysis and immunoprecipitation of the gV sPLA2 protein due in part to unavailability of a specific antibody against mouse gV sPLA2 and other issues, we used a monoclonal antibody against the Myc-tag to analyze gV sPLA2 knockdown (KD) RAW 264.7 cells with re-constitutive expression of Myc-tagged gV sPLA2 or Myc-tagged gV sPLA2-H48Q, lacking catalytic activity, as well as gV sPLA2 KD RAW 264.7 cells transfected with empty vector. Among the significant peaks, the region corresponding to -375 ~ +6 from the transcriptional start site of the Pgk1 (phosphoglycerate kinase 1) gene was the strongest binding peak in the nucleus of both gV sPLA2 KD cells expressing Myc-tagged gV sPLA2 and gV sPLA2 KD cells expressing Myc-tagged gV sPLA2-H48Q. Meanwhile, the Pgk1 gene was not identified as a significant peak in the nucleus of gV sPLA2 KD cells transfected with empty vector.
