Essential functions of the Glucocorticoid Receptor require direct DNA binding [ChIP-seq]

Project description:We performed ChIP-Sequencing for GR in GR wild-type, GR Zn mutant and GR Knock-Out Mouse Embryonic Fibroblasts (MEFs). We show that GR Zn mutant chromatin binding is mostly lost except for some tethered binding sites. Together with the corresponding RNA-Seq data, our results illustrate how GR requires direct DNA binding for activation and repression of target genes.

Chromatin immunoprecipitation and transcription of mouse liver in the presence or absence of exogenous glucocorticoid to identify direct targets of the glucocorticoid receptor

Project description: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. These were hybridized to the BCBC Mouse PancChip 5.0 and the Mouse PromoterChip BCBC-3.0 respectively.

Anti-inflammatory functions of the glucocorticoid receptor require DNA binding.

Project description:The glucocorticoid receptor is an important immunosuppressive drug target and metabolic regulator that acts as a ligand-gated transcription factor. Generally, GR's anti-inflammatory effects are attributed to the silencing of inflammatory genes, while its adverse effects are ascribed to the upregulation of metabolic targets. GR binding directly to DNA is proposed to activate, whereas GR tethering to pro-inflammatory transcription factors is thought to repress transcription. Using mice with a point mutation in GR's zinc finger, that still tether via protein-protein interactions while being unable to recognize DNA, we demonstrate that DNA binding is essential for both transcriptional activation and repression. Performing ChIP-Seq, RNA-Seq and proteomics under inflammatory conditions, we show that DNA recognition is required for the assembly of a functional co-regulator complex to mediate glucocorticoid responses. Our findings may contribute to the development of safer immunomodulators with fewer side effects.

Potentiation of glucocorticoid signaling by chloroquine via inhibition of lysosomes

Project description:Anti-malaria drug chloroquine has been used as an anti-inflammatory agent for treating systemic lupus erythematosus and rheumatoid arthritis, without clear mechanism of action. Here we report that chloroquine potently inhibits the expression of proinflammatory cytokines through transrepression of glucocorticoid receptor (GR). Instead of direct binding to GR, chloroquine synergistically activates glucocorticoid signaling via inhibition of lysosomal functions. In mouse collagen induced arthritis model, chloroquine synergizes the therapeutic effects of glucocorticoid. Lysosomal inhibition by bafilomycin A1, an inhibitor of V-type ATPase, or by knockdown of transcription factor EB (TFEB), a master activator of lysosomal biogenesis, mimics the effects of chloroquine. These results reveal an unexpected regulation of glucocorticoid signaling by lysosomes and provide a mechanistic basis for treating inflammation and autoimmune diseases by combination of glucocorticoids and lysosomal inhibitors. Macrophage THP-1 cells treated with LPS, chloroquine and dexamethasone.
