Chrousos syndrome:from molecular pathogenesis to

The search terms included 'primary generalized glucocorticoid resistance', 'Chrousos syndrome', 'glucocorticoid receptor gene' and 'glucocorticoid receptor mutations'. RESULTS:Only a few cases of Chrousos syndrome have been described to date, ranging from asymptomatic to severe forms of mineralocorticoid and/or androgen excess. Distribution of the mineralocorticoid and the The cellular localization of mineralocorticoid receptor (MR) and glucocorticoid receptor (GR) gene eion in the rat hippocampus was studied by in situ hybridization using 35 Slabeled RNAprobes, complementary to either 513 bases of the rat brain mineralocorticoid receptor (MR)mRNA or 500 bases of the rat liver glucocorticoid receptor (GR)mRNA.

Flow cytometry analysis of glucocorticoid receptor

Jul 14, 2009 · Glucocorticoid (GC) therapy is the main treatment for systemic lupus erythematosus (SLE). However, some patients are resistant to these agents. Abnormalities of glucocorticoid receptor (GR) seem to be related to steroid resistance. This study evaluated GRs in T lymphocytes and monocytes of SLE patients by flow cytometry (FCM) using a monoclonal antibody (mAb) and FITC Functional characterization of canine wild type Oct 24, 2019 · Glucocorticoids bind to the cytoplasmic glucocorticoid receptor (GR), which is eed in almost all cells. These receptors are key factors in determining individual sensitivity to glucocorticoids. This study examined individual differences in glucocorticoid sensitivity in dogs, focusing on reactivity of the GR to prednisolone.

Glucocorticoid Receptor - PubMed

Nov 21, 2020 · Glucocorticoid Receptor. The glucocorticoid receptor (GR) is an evolutionally conserved nuclear receptor superfamily protein that mediates the diverse actions of glucocorticoids as a ligand-dependent transcription factor. This receptor is a protein that shuttles from the cytoplasm to the nucleus upon binding to its ligand g . Glucocorticoid Receptor Gene Mutations - Cancer ResearchApr 01, 2000 · Glucocorticoid resistance was investigated in human leukemic CCRF-CEM cells. A mutation ( L753F ), which renders the human glucocorticoid receptor ( hGR ) gene functionally hemizygous, was identified in all CEM-derived cell lines analyzed. Allele-specific PCR identified the same mutation in lymph node biopsy material from patient CEM cells. Given the correlation between hGR

Glucocorticoid receptor action in metabolic and

Jul 24, 2017 · Abstract. Glucocorticoids via the glucocorticoid receptor (GR) have effects on a variety of cell types, eliciting important physiological responses via changes in gene eion and signaling. Although decades of research have illuminated the mechanism of how this important steroid receptor controls gene eion using in vitro and cell Glucocorticoid receptor modulation decreases ER-positive Jul 24, 2019 · Non-ER nuclear receptor activity can alter estrogen receptor (ER) chromatin association and resultant ER-mediated transcription. Consistent with GR modulation of ER activity, high tumor glucocorticoid receptor (GR) eion correlates with improved relapse-free survival in ER+ breast cancer (BC) patients. In vitro cell proliferation assays were used to assess ER-mediated BC cell

Glucocorticoid receptors and depression. The BMJ

The number of glucocorticoid receptor sites in lymphocytes was estimated and plasma cortisol concentrations measured in 17 depressed patients, 12 patients with chronic schizophrenia, and 31 healthy control subjects. The number of receptor sites was significantly lower in the depressed patients than in either the controls or the patients with chronic schizophrenia, but there were no differences Glucocorticoid-Mediated Induction of CYP3A4 is Decreased Sep 01, 2002 · CYP3A4 is the most abundant cytochrome P450 (P450) in human liver, comprising approximately 30% of the total liver P450 content. This enzyme has an important role in steroid catabolism and metabolism of foreign compounds, with the majority of pharmaceutical compounds being substrates for CYP3A4. The molecular mechanisms that underlie transcriptional activation of CYP3A4

Glucocorticoids Antagonize Estrogens by - Cancer Research

Sep 15, 2008 · In this study, we show that activation of glucocorticoid receptor (GR) by dexamethasone (DEX) induced the eion and activity of estrogen sulfotransferase (SULT1E1 or EST), an enzyme important for the metabolic deactivation of estrogens, because sulfonated estrogens fail to activate the estrogen receptor. Glucocorticoids:do we know how they work? Arthritis Jan 21, 2002 · It is not known to what extent glucocorticoid hormones cause their anti-inflammatory actions and their undesirable side effects by the same or different molecular mechanisms. Glucocorticoids combine with a cytoplasmic receptor that alters gene eion in two ways. One way is dependent on the receptor's binding directly to DNA and acting (positively or negatively) as a

IJMS Free Full-Text Roles of the Glucocorticoid and

The GC receptor (GR/NR3C1) and the mineralocorticoid receptor (MR/NR3C2) are members of the NR subclass NR3C that are highly related, both structurally and functionally. While the GR is ubiquitously eed and is almost exclusively activated by GCs; an MR has a more restricted tissue eion pattern and can bind GCs and the mineralocorticoid aldosterone with similar high affinity. Immune regulation by glucocorticoids Nature Reviews Feb 13, 2017 · Glucocorticoids receptors are eed by nearly all cells in the body, yet the effects of glucocorticoids vary by cell type. and research into glucocorticoid-mediated regulation of the

Is there a role for glucocorticoid receptor beta in asthma

Dec 18, 2000 · Abstract. Glucocorticoids (GCs) are routinely used as anti-inflammatory drugs in the treatment of asthma. They act through binding to glucocorticoid receptor (GR), which represses numerous genes encoding pro-inflammatory mediators. A hormone binding deficient GR isoform named GR has been isolated in humans. Mineralocorticoid Receptors and Glucocorticoid Receptors The glucocorticoid hormones cortisol and corticosterone coordinate circadian events and are master regulators of the stress response. These actions of the glucocorticoids are mediated by mineralocorticoid receptors ( NR3C2, or MRs) and glucocorticoid receptors ( NR3C1, or GRs). MRs bind the natural glucocorticoids cortisol and corticosterone with a 10-fold higher affinity than GRs.

Molecular mechanisms:Stress pathway dysregulated in

Apr 27, 2012 · Glucocorticoid receptors have been shown to regulate the eion of two MeCP2-dependent genes in mice 4. Blocking these receptors returns the eion of these genes to normal levels and relieves Rett-like symptoms such as hind-limb clasping, which may mimic the hand flapping seen in individuals with the syndrome, the study found. Role of skeletal muscle glucocorticoid receptor in Nov 01, 2017 · Skeletal muscle glucocorticoid receptor controls muscle mass and plasma alanine concentrations. Skeletal muscle-liver-fat signaling axis is the interplay between organ systems playing an important role in mediating the metabolic actions of glucocorticoids.

Stress Signals, Mediated by Membranous Glucocorticoid

Glucocorticoids (GCs), key mediators of stress signals, are also potent wound healing inhibitors. To understand how stress signals inhibit wound healing, we investigated the role of membranous glucocorticoid receptor (mbGR) by using cell-impermeable BSA-conjugated dexamethasone. Structures of the glucocorticoid-bound adhesion receptor Jan 06, 2021 · The orphan receptor GPR97 is a member of the adhesion GPCR (aGPCR) family 1,2,3.As one of the evolutionarily ancient families in the GPCR superfamily, aGPCRs are crucial molecular switches that
