Expression data from human alternatively activated macrophages

ABSTRACT: 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. Monocytes from 2 donors were used and treated as indicated in Summary. Technical replicates were generated from each sample.

Immunity 20101101 5

Peroxisome proliferator-activated receptor γ (PPARγ) is a lipid-activated transcription factor regulating lipid metabolism and inflammatory response in macrophages and dendritic cells (DCs). These immune cells exposed to distinct inflammatory milieu show cell type specification as a result of altered gene expression. We demonstrate here a mechanism how inflammatory molecules modulate PPARγ signaling in distinct subsets of cells. Proinflammatory molecules inhibited whereas interleukin-4 (IL-4) st ...[more]

Expression data from human macrophages

Project description: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. Monocytes from 3 donors were used and treated as indicated in Summary.

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. 3 C57Bl/6 wild-type and 3 STAT6 KO 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.

Functional and cellular constraints that shaped the PPARg binding landscape in human and mouse macrophages: human expression

Project description:Genome-wide comparisons of transcription factor binding sites in different species allow for a direct evaluation of the evolutionary constraints that shape transcription factor binding landscapes. To gain insights into the evolution of the PPARg-dependent transcriptional network we obtained binding data for PPARg, RXR and PU.1 in human macrophages and compared the profiles to matching data from mouse macrophages. We found that PPARg binding was highly divergent and only 5% of the PPARg bound regions were occupied in both species. Despite the low conservation of PPARg binding sites, conserved PPARg target genes contribute more than 30% to the functional target genes identified in human macrophages. In addition conserved target genes are strongly enriched for lipid metabolic functions. We detected the lineage-specification factor PU.1 at the majority of human PPARg binding sites. This confirmed the juxtaposed binding configuration found in mouse macrophages and demonstrated the preservation of tissue-specific adjacent PPARg-Pu.1 binding in the absence of individual binding site conservation. Finally, based on this of PPARg and PU.1 binding between human and mouse we suggest a mechanism by which PU.1 facilitates PPARg binding site turnover in macrophages. Comparison of RNAs level in Rosiglitazone (RSG) and vehicle (DMSO) treated PMA differentiated THP-1 cells over a timecourse from 0.5h to 12h

Effect of dietary abscisic acid (ABA) supplementation on spleen transcriptome in LPS-challenged mice

Project description:BACKGROUND: Dietary ABA-supplementation modulates immune and inflammatory responses in mouse models of chronic and infectious disease. However, the underlying mechanisms by which ABA elicits its immune modulatory effects are not well understood. This project used a systems approach in combination with functional and in vivo studies to investigate the target gene pathways modulated by ABA in the context of an inflammatory LPS challenge. RESULTS: Dietary ABA-supplementation regulates the expression of gene pathways associated with peroxisome proliferator-activated receptor gamma (PPAR g), cAMP signaling and lipid metabolism in PPAR g-expressing mice. However, the pattern of differentially expressed genes is significantly reduced in the spleens of tissue-specific PPAR g null mice fed ABA. These differences in gene expression coincided with enhanced PPAR g-reporter activity of macrophages treated with ABA and enhanced intracellular cAMP accumulation in ABA-treated splenocytes. Splenocytes from wild-type (WT) and Null (epithelial and immune cell-specific PPARg knock-out) mice were sampled with or without ABA supplementation and with or without LPS stimulation.
