Expression data from human macrophages

ABSTRACT: Human CD14 positive monocytes were purified from healthy volunteers’ blood and cultured in vitro for 4, 12, 24, 72 hours. While culturing, macrophages were activated alternatively with interleukin-4 (IL-4 100 ng/ml) or classically with interferon-gamma (IFNg 100 ng/ml)+tumor necrosis factor (TNF 50 ng/ml) or left without activation. Simultaneously, macrophages were also treated with vehicle (DMSO:ethanol) or 1mM synthetic PPARg agonist, Rosiglitazone. We used Affymetrix microarrays (U133Plus 2.0) to analyze activation and PPARg-induced gene expression changes.

Expression data from human alternatively activated macrophages

Project description:Human CD14 positive monocytes were purified from healthy volunteers’ blood and cultured in vitro for 6 hours. While culturing, macrophages were activated alternatively with interleukin-4 (IL-4 100 ng/ml). Simultaneously, macrophages were also treated with vehicle (DMSO:ethanol) or 1uM synthetic PPARg agonist, Rosiglitazone. We used Affymetrix microarrays (U133Plus 2.0) to analyze activation and PPARg-induced gene expression changes.

PPARg and IL-4-induced gene expression data from PPARg +/- LysCre and PPARg fl/- LysCre mouse bone marrow-derived alternatively activated macrophages and immature dendritic cells (iDCs)

Project description:Conditional macrophage-specific PPARg knockout mice were generated on C57Bl/6 background by breeding PPARg fl/- (one allele is floxed, the other is null) and lysozyme Cre transgenic mice. PPARg and IL-4 signaling was analyzed on bone marrow-derived macrophages. Bone marrow of 4 mice per group was isolated and differentiated to alternatively activated macrophages with 20 ng/ml M-CSF and 20 ng/ml IL-4 or to iDCs with 20 ng/ml GM-CSF+20 ng/ml IL-4. 1 uM Rosiglitazone (RSG) was used to activate PPARg. From each mouse 4 samples were generated: 1. M-CSF+IL-4, 2. M-CSF+IL-4+RSG, 3. GM-CSF+IL-4 and 4. GM-CSF+IL-4+RSG. All compounds were added throughout the whole differentiation process, and fresh media was added every other day. Control cells were treated with vehicle (DMSO:ethanol). After 9 days, RNA was isolated and gene expression profiles were analyzed using ABI Mouse Genome Survey Arrays.

PPARg and IL-4-induced gene expression data from PPARg +/- LysCre and PPARg fl/- LysCre mouse bone marrow-derived macrophages

Project description:Conditional macrophage-specific PPARg knockout mice were generated on C57Bl/6 background by breeding PPARg fl/- (one allele is floxed, the other is null) and lysozyme Cre transgenic mice. PPARg and IL-4 signaling was analyzed on bone marrow-derived macrophages. Bone marrow of 3 mice per group was isolated and differentiated to macrophages with M-CSF (20 ng/ml). 20 ng/ml IL-4 was used to induce alternative macrophage activation and 1 uM Rosiglitazone (RSG) was used to activate PPARg. From each mouse 4 samples were generated: 1. M-CSF, 2. M-CSF+RSG, 3. IL-4 and 4. IL-4+RSG. All compounds were added throughout the whole differentiation process, and fresh media was added every other day. Control cells were treated with vehicle (DMSO:ethanol). After 10 days, RNA was isolated and gene expression profiles were analyzed using Mouse Genome 430 2.0 microarrays from Affymetrix. 3 PPARg +/- LysCre and 3 PPARg fl/- LysCre mice were used to isolate bone marrow and from each macrophages were differentiated with or without IL-4 and simultaneously treated with vehicle or RSG. Altogether we analyzed 24 samples with 3 biological replicates as below.

PPARg and IL-4-induced gene expression data from wild-type and STAT6 knockout mouse bone marrow-derived macrophages

Project description:C57Bl/6 wild-type and STAT6 KO mice were used to study PPARg and IL-4 signaling. Bone marrow of 3 mice per group was isolated and differentiated to macrophages with M-CSF (20 ng/ml). 20 ng/ml IL-4 was used to induce alternative macrophage activation and 1 uM Rosiglitazone (RSG) was used to activate PPARg. From each mouse 4 samples were generated: 1. M-CSF, 2. M-CSF+RSG, 3. IL-4 and 4. IL-4+RSG. All compounds were added throughout the whole differentiation process, and frech media was added every other day. Control cells were treated with vehicle (DMSO:ethanol). After 10 days, RNA was isolated and gene expression profiles were analyzed using Mouse Genome 430 2.0 microarrays from Affymetrix.

Differential repression of TLR responses by PPARg and LXRs

Project description:Transrepression mediated by PPARg and LXRs agonists (GW7845 and GW3965) in primary macrophages stimulated with LPS or poly I:C. Thioglycollate-elicited macrophages were isolated from mice by peritoneal lavage 3 days following peritoneal injection of 2.5 ml 3% thioglycollate (DIFCO). Cells were plated in RPMI medium 1640 and 10% fetal bovine serum, washed after 5 h the medium was removed and cells were fed with fresh medium containing 0.5% fetal bovine serum. Cells were treated with LPS (Sigma) a concentration of 100 ng/ml or poly I:C (100 ng/ml) in the absence or presence of receptor-specific agonists for PPARγ (GW7845) or LXR (GW3965) at 1 µM concentrations. Results suggest signal-dependent nuclear receptors transrepression pathways.
