GenomicsGlucocorticoid Receptor and Androgen Receptor DNA binding in LREX'
LREX' are a LnCAP/AR subline with natural expresison of the glucocorticoid receptor. We used the model to compare the AR and GR cistromes in prostate tissue. We determined the GR cistrone in the presence of Dex (100nM) treatment and the AR cistrome in the presene of DHT (1nM) treatment.

GenomicsGlucocorticoid receptor profiling in U2OS cells expressing GRalpha or GRgamma isoform
To determine whether insertion of a single amino acid had an effect on Glucocorticoid receptor (GR) occupancy, we performed ChIP-seq of GRalpha and GRgamma in the same U2OS osteosarcoma cell lines, upon glucocorticoid treatment. These assays are also part of submission E-MTAB-2955

TranscriptomicsChromatin immunoprecipitation and transcription of mouse liver in the presence or absence of exogenous glucocorticoid to identify direct targets of the glucocorticoid receptor
The purpose of this study was to identify direct targets of the glucocorticoid receptor (GR) using an orthogonal analysis. An expression study of mouse livers in the presence or absence of exogenous glucocorticoid complemented a genome-wide location analysis on chromatin from the same livers. Thes...

TranscriptomicsRole of Serine 134 phosphorylation of the glucocorticoid receptor (GR) in glucocorticoid signaling
In response to environmental stressors and a variety of inflammatory cytokines, p38 MAPKs become directly activated. Here we report the human glucocorticoid receptor (GR) Serine 134 as a novel target for p38 MAPK. Unlike most other phosphorylation events that occur on the GR, phosphorylation of Ser1...

TranscriptomicsHes1 and Liver Glucocorticoid Signaling
To investigate the role of HES1 during glucocorticoid signaling in the liver, we employed whole-genome microarray expressions in liver mRNA extracted from control and Hes1-liver knockout male mice (HESKOL) that had been adrenalectomized to remove endogenous glucocorticoids. RNA isolated from the liv...

TranscriptomicsCryptochromes mediate rhythmic repression of the glucocorticoid receptor
The circadian transcriptional repressors cryptochromes 1 (Cry1) and 2 (Cry2) interact with the C-terminus of the glucocorticoid receptor (GR) and are required for transrepression in response to the synthetic GR ligand dexamethasone (Dex) in mouse embryonic fibroblasts. Dex induction of many genes w...

no omics definedTranscription profiling of human U-2 osteosarcoma cell lines expressing different glucocorticoid receptor isoforms - time series
Glucocorticoids regulate diverse physiologic processes and synthetic derivatives of these natural hormones are widely used in the treatment of inflammatory diseases. However, chronic administration often triggers insensitivity and serious side effects including osteoporosis. The underlying mechanis...

GenomicsLigand-dependent genomic function of glucocorticoid receptor in triple-negative breast cancer
Glucocorticoids (GC) have been widely used as coadjuvants in the treatment of solid tumors, but GC treatment may be associated with poor pharmacotherapeutic response and/or prognosis. The genomic action of GC in these tumors is largely unknown. Here we find that dexamethasone (Dex, a synthetic GC) r...

TranscriptomicsHNF4A is required to specify glucocorticoid action in the liver - RNAseq
The glucocorticoid receptor (GR) is a nuclear hormone receptor critical to the regulation of energy metabolism and the inflammatory response. The actions of GR have been shown to be highly dependent on context. Here, we demonstrate the necessity for liver lineage-determining factor hepatocyte nuclea...

TranscriptomicsExpression data in the mouse brain following the glucocorticoid receptor overexpression in the forebrain (GRov) during different periods in development
The glucocorticoid receptor overexpression in early life is sufficient to alter gene expression patterns for the rest of the animal's life. Hippocampal dentate gyrus (DG) are more responsive than the nucleus accumbens (NAcc) following the glucocorticoid receptor overexpression in the forebrain. Lase...
