Expression data from RAW 264.7 macrophage

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.

Genome-wide maps of gV sPLA2 binding sites in Raw 264.7 cells

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.

Next Generation Sequencing of Wild Type and Hnrnpul1-/- RAW 264.7 Cells Transcriptomes

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.

LPS stimulation of Mouse (RAW 264.7) macrophages

Project description:Immunoresponsive gene 1 (IRG1) is one of the highest induced genes in macrophages under pro-inflammatory conditions and its function has been recently described: it codes for immune-responsive gene 1 protein/cis-aconitic acid decarboxylase (IRG1/CAD), an enzyme catalyzing the production of itaconic acid from cis-aconitic acid, a tricarboxylic acid (TCA) cycle intermediate. Itaconic acid possesses specific antimicrobial properties inhibiting isocitrate lyase, the first enzyme of the glyoxylate shunt, an anaplerotic pathway that bypasses the TCA cycle and enables bacteria to survive on limited carbon conditions. To elucidate the mechanisms underlying itaconic acid production through IRG1 induction in macrophages, we examined the transcriptional regulation of IRG1. Using a combination of literature information, transcription factor prediction models and genome-wide expression arrays, we inferred the regulatory network of IRG1 in mouse and human macrophages. 3 unstimulated (Control) and 3 LPS-stimulated RAW 264.7 macrophages
