Project description:Gfi1 is a transcription factor broadly participate in differentiation of immune cells and loss of Gfi1 could result in severe neutrophil deficiency. To gain insight into the consequences of lack of Gfi1 on a genome-wide level, we conducted genome-wide transcriptome profiling in Wide-type (WT) and Gfi1–/– Raw264.7 macrophage cells using Affymetrix Mouse 3’ IVT microarrays
Project description:Mouse RAW264.7 macrophages were treated with LPS, IFNb, poly(rI:rC), poly(dA:dT), VSV, HSV, Sendai virus. Genes identified by Human Innate Immunity Interactome for type I Interferon (HI5) were examined for expression. qPCR gene expression profiling. RAW264.7 macrophages were used and treated separately as indicated in the summary. Equal amount total RNA from each group was used for gene expression analysis.
Project description:To identify novel LXR target genes, we conducted transcriptional profiling studies using RAW264.7 cells ectopically expressing LXRalpha Total RNA was isolated from RAW264.7 macrophages ectopically expressing LXRalpha as described in Venkateswaran et al. (2000); PNAS 97, 12097-12102. Cells were cultured with DMSO or GW3965 (1 μM) and LG268 (100 nM). Transcriptional profiling was performed at the UCLA microarray core facility using murine Affymetrix 430 2.0 microarrays.
Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to evaluate the gene expression of E4BP4 knockout (KO) RAW264.7 cells. Methods: We generated E4BP4-KO RAW264.7 Cell Line using CRISPR-CAS9 system. Control plasmid was encoding the Cas9 nuclease without gRNA sequence. Total RNA of E4BP4-KO and Control (CTRL) RAW264.7 cells was extracted. RAW264.7 cells RNA profiles were generated by deep sequencing for two groups (E4BP4-KO versus CTRL RAW264.7 cells) with three samples each. Results: There were significant differences between E4BP4-KO and CTRL RAW264.7 cells. Conclusions: Deletion of E4BP4 in RAW264.7 cells induced various changes at the transcription level.
Project description:This SuperSeries is composed of the following subset Series:; GSE4938: murine CD4+ and CD8+ T-cells from wildtype and Gfi knockout cells; GSE4940: murine T-cells from wildtype and Gfi1 knockout mice activated by anti-CD3 plus anti-CD28 for 0 to 24h Experiment Overall Design: Refer to individual Series
Project description:Gene expression profile of FABP4 treatment in RAW264.7 macrophages was examined to show a ligand (palmitic acid)-dependent and a ligand-independent effect of FABP4. RAW264.7 macrophages were treated with and without 200 nM recombinant FABP4 in the absence and presence of 0.2 mM palmitic acid.
Project description:RAW264.7 mouse macrophages were transfected with negative control and miR-342-3p mimics and subjected to microarray analysis 18 hours after the transfection. We used microarray to obtain global mRNA expression data of negative control and miR-342-3p mimics-transfected RAW264.7 cells.
