Project description:Genome wide binding of glucocorticoid receptor in dexamethasone treated mouse bone marrow derived macrophages
| PRJNA262583 | ENA
Project description:Macrophages are amongst the major targets of glucocorticoids (GC) as therapeutic anti-inflammatory agents. Here we show that GC treatment of mouse and human macrophages initiates a cascade of induced gene expression including many anti-inflammatory genes. Inducible binding of the glucocorticoid receptor (GR) was detected at candidate enhancers in the vicinity of induced genes in both species and this was strongly associated with canonical GR binding motifs. However, the sets of inducible genes, the candidate enhancers, and the GR motifs within them, were highly-divergent between the two species.. The data cast further doubt upon the predictive value of mouse models of inflammatory disease. human monocyte derived macrophages were treated with dexamethasone for 2h, fixed and ChIP performed. Material from 4 volunteers was pooled for the IP.

Project description:An unresolved molecular paradox is how the glucocorticoid receptor (GR) activates some genes while potently repressing others. We carried out genome-wide localization and expression profiling experiments in primary bone marrow-derived mouse macrophages treated with Dexamethasone in the presence or absence of LPS. Unexpectedly, we find that the anti-inflammatory GR cistrome, which is principally composed of 'canonical' GREs colocalizing with NFkB and AP-1 co-enriched with the myeloid lineage factors C/EBP and Pu.1, is shaped by TLR4-directed chromatin dynamics, suggesting that context rather than sequence may be a critical determinant of function. Identification of GR, cJun, NFkB(p65) binding sites in primary bone-marrow derived macrophages unstimulated and LPS-stimulated (3hrs) that were untreated or pre-treated with Dexamethasone for 16 hrs

Project description:To identify cross-talk between the cytoplasmic kinase AMPK and the nuclear receptor, glucocorticoid receptor, during inflammatory responses, bone-marrow-derived macrophages lacking the catalytic domain of AMPK, AMPKa1, were exposed to vehicle, dexamethasone, a synthetic glucocorticoid, lipopolysaccharide, crushed muscle extract (damage-associated molecular patterns) or a combination of the inflammatory stimulus and dexamethasone.

Project description:Glucocorticoids are critical components of combination chemotherapy regimens in pediatric acute lymphoblastic leukemia (ALL). However, the signaling pathways regulating apoptosis in glucocorticoid-treated lymphoid cells remain unclear. In this study, pediatric ALL patient-derived xenograft inherently sensitive to glucocorticoids were exposed to dexamethasone in vivo. Whole-genome GR binding sites and histone acetylation status were detected using chromatin immunoprecipitation sequencing analyses. This provided a global understanding of dexamethasone-induced DNA modulations in ALL cells in vivo, which is likely to be important in the understanding of mechanisms of glucocorticoid response in lymphoid malignancies. One xenograft (ALL-54) was derived from a patient of dexamethasone-good responder. The xenograft was innoculated into 2 NOD/SCID mice, and treated with dexamethasone (15 mg/kg) or vehicle control. Binding of glucocorticoid receptor (GR), histone acetylation and IgG control in spleen-harvest xenograft samples were detected using ChIP-seq.

Project description:Glucocorticoid receptor is a transcription factor that is ubiquitously expressed. Glucocorticoids are circadian steroids that regulate a wide range of bodily functions, including immunity. Here we report that synthetic glucocorticoids affect 1035 mRNAs in isolated healthy human blood monocytes but only 165 in the respective six day-old monocyte-derived macrophages. The majority of the glucocorticoid response in monocytes concerns genes that are dynamic upon monocyte to macrophage differentiation, whereby macrophage-like mRNA levels are often reached in monocytes within four hours of treatment. Concomitantly, over 5000 chromosomal H3K27ac regions undergo remodelling, of which 60% involve increased H3K27ac signal. We find that chromosomal glucocorticoid receptor binding sites correlate with positive but not with negative local epigenomic effects. To investigate further we assigned our data to topologically associating domains (TADs). This shows that about 10% of macrophage TADs harbour at least one GR binding site and that half of all the glucocorticoid-induced H3K27ac regions are confined to these TADs. Our analyses are therefore consistent with the notion that TADs naturally accommodate information from sets of distal glucocorticoid response elements.
