To determine the global gene expression response in murine LPS-induced macrophages treated with a bromodomain inhibitor.

ABSTRACT: Bone marrow-derived macrophages, Unstimulated DMSO Bone marrow-derived macrophages, Unstimulated + I-BET (GSK525762A) Bone marrow-derived macrophages, LPS 1h DMSO Bone marrow-derived macrophages, LPS 1h + I-BET (GSK525762A) Bone marrow-derived macrophages, LPS 2h DMSO Bone marrow-derived macrophages, LPS 2h + I-BET (GSK525762A) Bone marrow-derived macrophages, LPS 4h DMSO Bone marrow-derived macrophages, LPS 4h + I-BET (GSK525762A) LPS (100 ng/mL) was purchased from Sigma. Bone Marrow-derived macrophages (BMDMs) were differentiated from C57BL/6 bone marrow using 5 ng/mL each of recombinant M-CSF and IL-3 (Peprotech) for 7 days as described (Jeffrey et al, Nature Immunology, 2006). 2 x10^6 BMDMs were treated with DMSO or 1 μM of I-BET for 30 minutes before the addition of LPS (100 ng/mL) for 1, 2 or 4h. Unstimulated control samples were incubated with I-BET only for 1 hour. 500 ng of total RNA from 3 independent samples per group was used to prepare biotin-labeled RNA using Ambion Illumina TotalPrep RNA Amplification Kit (Applied Biosystems) and hybridized to Illumina MouseRef-8 v2.0 expression BeadChip kits. The chips were scanned using Illumina BeadArray Reader. 3 biological replicates and 4 timepoints

Control of LPS induced gene expression in bone marrow derived macrophages by the p50/p105 subunit of NF-kB and IL-10

Project description:Bone marrow-derived macrophages were produced from mice lacking IL-10 alone (IL10-def) or mice lacking both IL-10 and the p50/p105 subunit of NF-kB (p50/IL10), and left unstimulated, stimulated with LPS (1 ng/ml) or stimulated with LPS and IL-10 (0.3 ng/ml). There are 12 total samples, with 2 each from the groups described in the summary. Pairwise comparisons between groups were evaluated.

Knockout of the selenocysteine tRNA (Trsp) gene in mouse macrophage

Project description:Comparative analysis of gene expression in bone marrow-derived macrophages (BMDM) from trsp knockout mice (Trspfl/fl-LysM-Cre+/-) and Control (Trspfl/fl-LysM-Cre-/-) mice. Selenium, a micronutrient whose deficiency in the diet causes immune dysfunction and inflammatory disorders, exerts its physiological effects partly in the form of selenium-containing proteins (selenoproteins). Incorporation of selenium into the amino acid selenocysteine (Sec), and subsequently into selenoproteins, is mediated by Sec tRNA[Ser]Sec. To identify macrophage-specific selenoprotein function, we generated mice with the Sec tRNA[Ser]Sec gene specifically deleted in myeloid cells. These mutant mice were devoid of the selenoproteome in macrophages, yet exhibited largely normal inflammatory responses. However, selenoprotein deficiency led to aberrant expression of extracellular matrix-related genes, and diminished migration of macrophages in a protein gel matrix. Therefore, selenium status may affect immune defense and tissue homeostasis through its effect on selenoprotein expression and the trafficking of tissue macrophages. We have generated mice in which we have selectively removed the selenocysteine tRNA gene (trsp) in macrophages under the control of LysM-Cre promoter. Microarray analysis was performed on RNA samples taken from bone marrow-derived macrophages in knockout and control mice. 1. Control unstimulated 2. Knockout unstimulated 3. Control lipopolysaccharide (LPS) stimulated (4h) 4. Knockout LPS stimulated (4h). Three replicates for each condition. Thus, a total of 12 samples.

Effect of SOCS3 on the transcriptional response of bone marrow-derived macrophages to IL-6

Project description:Effects of SOCS3 on the transcriptional response of bone marrow-derived macrophages to IL-6. Fetal liver cells from SOCS3+/+ or SOCS3-/- embryos were used to reconstitute recipient mice. Donor derived bone marrow from these mice was differentiated to macrophages. Macrophages were either unstimulated, or stimulated for 100 or 400 minutes with 10 ng/ml IL-6. Keywords = macrophage, SOCS3, IL-6, interferon Keywords: repeat sample

Project description:Proteomics of carboxylated polystyrene bead (1.0 um) phagosomes from murine bone marrow-derived macrophages. cells were either resting or treated with 100 U/ml IFN-γ (PeproTech) and 100 ng/ml LPS (Sigma) for 24 h, 20 ng/ml Interleukin-4 (IL4) (BD Pharmingen) for 48 h, 20 ng/ml Interleukin-13 (IL13), 10 ng/ml Interleukin-10 (IL10)for 48 h or Reprogrammed (IL4 was incubated with BMDMs for 24 h, and the medium was replaced with fresh medium containing IFN-γ/LPS to incubate for another 24 h). Phagosomes were isolated after 30 min bead inoculation.
