Project description:The human glucocorticoid receptor (GRα) is overexpressed at the molecular and protein level in malignant human adrenocortical cancers. A stable cell line model of GRα overexpression was established using the H295R human adrenocortical cancer cell line. The following results were obtained from gene expression profiling of H295R_GRα and H295R_Control (empty vector) cells following treatment with either a GRα agonist (dexamethasone), GRα antagonist (RU486) or vehicle (ethanol) control. H295R_GRα and H295R_Control (empty vector) cells were treated in triplicate for 6 hours with dexamethasone 100 nM, RU486 100 nM or vehicle (ethanol) control.
Project description:Neurosphere cultures prepared from E14.5 mouse cerebral cortex at passage 3 were treated for 4 hours with 100 nM dexamethasone We used microarrays to detail the global program of dexamethasone regulated gene expression in embryonic neural progenitor/stem cells. Cerebral cortex was isolated from E14.5 mouse fetuses and cultured as neurospheres for 3 passages prior to treatment with 100 nM dexamethasone or ethanol vehicle for 4 hours.
Project description:We performed ATAC-seq in the A549 cell line. Cells were treated with dexamethasone (100 nM), hydrocortisone (100 nM) or vehicle (ethanol) for 4 hours and either harvested immediately or washed 2x with PBS and subsequently cultured in hormone-free medium for 24 hours before harvest.
Project description:We performed ATAC-seq in the A549 cell line. Cells were treated with dexamethasone (100 nM), hydrocortisone (100 nM) or vehicle (ethanol) for 20 hours and either harvested immediately or washed 2x with PBS and subsequently cultured in hormone-free medium for 24 hours before harvest.
Project description:We performed ATAC-seq in the A549 cell line. Cells were treated with either 100 nM dexamethasone or 0.1% ethanol. After 4 hours, cells were washed 2x with PBS and cultured in hormone-free medium for 24 hours, after which cells were treated again for 4 hours with either 100 nM dexamethasone or 0.1% ethanol.
Project description:We performed total RNA-seq in the A549 cell line. Cells were treated with either 100 nM dexamethasone or 0.1% ethanol. After 4 hours, cells were washed 2x with PBS and cultured in hormone-free medium for 24 hours, after which cells were treated again for 4 hours with either 100 nM dexamethasone or 0.1% ethanol.
Project description:We performed ATAC-seq in the U2OS-GR cell line. The cell line is derived from U2OS ATTC:HTB-96 and stably transfected with an expression construct for rat GR. Cells were treated with dexamethasone (100 nM) or vehicle (ethanol) for 4 hours and either harvested immediately or washed 2x with PBS and subsequently cultured in hormone-free medium for 24 hours before harvest.
Project description:The objective of this study was to determine binding patterns for GR, 65 and RNAP2 in Beas-2B airway epithelial cells after treatment with dexamethasone (100 nm), TNF (20 ng/ml) or both for one hour. This study utilized duplicate samples for each treatment condition and immunoprecipitation except for p65 immunoprcipitation of TNF treated samples, which was analyzed as a single sample. Input from vehicle treated cells was used a control. Experimental comparisons were made between the following samples/ treatment conditions. Duplicate samples of Beas-2B cells treated with ethanol (vehicle) were used for ChIP of GR, p65, and RNAP2 (2 samples each antibody). Duplicate samples of Beas-2B cells treated with dexamethasone were used for ChIP of GR and RNAP2 (2 samples each antibody). Duplicate samples of Beas-2B cells treated with TNF were used for ChIP of p65 and RNAP2 (1 sample p65, 2 samples RNAP2). Duplicate samples of Beas-2B cells treated with dexamethasone + TNF were used for ChIP of GR, p65 and RNAP2 (2 samples each antibody).
Project description:Wild-type bone marrow-derived macrophages (BMDMs) were treated with vehicle (0.1% EtOH/D-PBS), 6h 100 ng/ml lipopolysaccharide (LPS) or 16h 1uM dexamethasone (Dex) and 6h 100 ng/ml LPS (Dex+LPS) and mRNA expression analysed by RNA-Seq.
