Project description:Murine RAW 264.7 peritoneal macrophages were treated with 250 ppm Carbon monoxide (CO) for 3 hours prior to the addition of LPS (10 ng/ml) and then for the subsequent 4 hours of the study. Air-treated cells were maintained for the same time without CO. Total RNA was harvested at 0, 15, 30, 60, 120 and 240 min after LPS addition. CRNA was produced using standard Affymetrix procedures from 10µg of total RNA. The expression values of all probe sets are scaled to a target intensity of 500 by using Affymetrix Microarray Suite 5.0 Keywords = macrophage Keywords = inflammation Keywords = endotoxin Keywords = gene expression Keywords: time-course
Project description:This series compares gene expression in chicken peripheral blood lymphocyte (PBL) derived macrophages following stimulation with either XL10 E. coli or S. typh LPS over an 8 hour time course (0,1,2,4,and 8 hours). For the late time points, the stimuli were removed after 2 hours and fresh media was added for the remaining time. Keywords: time-course
Project description:To determine the effect of Aeroplysinin-1 (Ap) on gene expression, we treated murine RAW264.7 macrophages (ATCC TIB-71) with DMSO control or Aeroplysinin-1 (1uM) for 2 hours. Unstimulated and LPS stimulated (0.1ug/mL) conditions were investigated. Three biological replicates were used per group for RNASeq analysis. Derivatives of Aeroplysinin-1 were also tested (Ap7, Ap-9) at the same concentration and time points. Aligned reads
Project description:We studied the lipidome (236 individual lipid species including sphingolipids, ceramides, cholesterol, gangliosides, phosphatidylethanolamines) in basal and LPS-stimulated human monocyte derived macrophages (MDMs) over a time-course by LC-MS (30min, 3h, 8h, 16h; n=12 human donors). In order to explore how transcriptomic changes induced by LPS stimulation can correlate with changes in the lipidome, we performed RNAsequencing on MDMs from 4 donors over a time-course (30min, 3h, 8h, 16h)
Project description:Nuclear interaction studies by ChIP coupled with mass spectrometry identified the COMPASS/SETD1A complex as interaction partner of the glucocorticoid receptor (GR) in murine bone marrow-derived macrophages (BMDMs). Here, we profiled H3K4me1, H3K4me2 and H3K4me3 in wild-type and Setd1a hypermorphic (Setd1aDel/+) Raw264.7 cells after LPS and Dex+LPS stimulation by spike-in ChIP-Seq.
Project description:Setd1bKO primary murine bone marrow-derived macrophages (BMDMs) were treated with lipopolysaccharide (LPS) or dexamethasone and LPS (Dex+LPS) and gene expression differences in response to treatment analysed by PolyA RNA-Sequencing. No Dex-treatment dependent gene expression differences were identified. Setd1aDel/+ Raw264.7 cells with reduced Setd1a expression were analyzed with regards to their reponse to Dex when inflammatorily challenged with LPS by mRNA-Seq. We observed reduced GR-dependent gene acivation in Setd1a hypermorphic Raw264.7 cells. Wild type and Setd1aDel/+ Raw264.7 cells were treated with LPS or LPS and interferon beta (IFNB1) to show the IFNB1-dependent loss of gene expression in LPS-stimulated Setd1aDel/+ cells.
Project description:To understand a novel function of nucleolus during infectious conditions, we purified cytoplasmic, nucleoplasmic, and nucleolar fractions from macrophages for a time course of LPS stimulation and performed RNA-seq.
