1. Glucocorticoids are widely used for the suppression of inflammation in chronic inflammatory diseases such as asthma, rheumatoid arthritis, inflammatory bowel disease and autoimmune diseases, all of which are associated with increased expression of inflammatory genes. The molecular mechanisms involved in this anti-inflammatory action of glucocorticoids is discussed, particularly in asthma, wh...

The adrenal cortex plays a key role in the regulation of metabolism, salt and water homeostasis sex differentiation by synthesizing glucocorticoid, mineralocorticoid androgen hormones. Evidence exists that angiotensin II regulates adrenocortical function it has been contended peptides non-canonical branch renin system (RAS) might also modulate steroidogenesis adrenals. Thus, aim this review is ...

The glucocorticoid receptor resource focuses on the structure-function relationships of the glucocorticoid receptor. As well as links to sequence and bibliographic databases via the World Wide Web, the database contains sequence comparisons of receptors from different species and source information for glucocorticoid receptor clones, probes, cell lines and antibodies. The resource allows the el...

Lymphoid cells contain specific receptors for glucocorticoids. We have used [3H]dexamethasone-21-mesylate to label covalently glucocorticoid receptors in rat thymic lymphocytes and in neoplastic cells obtained from patients with acute lymphoblastic leukemia and malignant lymphoma. The covalently labeled glu cocorticoid receptors were identified by polyacrylamide gel electrophoresis (in the pres...

OBJECTIVE To gain better insight into the role of glucocorticoids as modulators of cell growth, as well as to investigate the presence and characteristics of glucocorticoid receptors (GR) in mouse melanoma cells. METHODS In two different B16 mouse melanoma cell clones (B16/F10 and B16/C3) the role of synthetic glucocorticoids (triamcinolone acetonide, TA) as cell growth modulators was investi...

Fetal glucocorticoid exposure is a key mechanism proposed to underlie prenatal 'programming' of adult affective behaviours such as depression and anxiety. Indeed, the glucocorticoid metabolising enzyme 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2), which is highly expressed in the placenta and the developing fetus, acts as a protective barrier from the high maternal glucocorticoids which m...

After binding to enhancer elements, transcription factors require transcriptional coactivator proteins to mediate their stimulation of transcription initiation. A search for possible coactivators for steroid hormone receptors resulted in identification of glucocorticoid receptor interacting protein 1 (GRIP1). The complete coding sequence for GRIP1, isolated from a mouse brain cDNA library, cont...

The hippocampus is the principal target site in the brain for adrenocortical steroids, as it has the highest concentration of receptor sites for glucocorticoids. The aged rat has a specific deficit in hippocampal glucocorticoid receptors, owing in large part to a loss of corticoid-sensitive neurons. This deficit may be the cause for the failure of aged rats to terminate corticosterone secretion...

The activation in vitro of dioxin and glucocorticoid receptors from a non-DNA binding to a DNA binding state was characterized. Ligand-free dioxin and glucocorticoid receptors were partially co-purified from rat liver cytosol, and both receptors sedimented at 9 S following labeling with the respective ligand. The 9 S forms of the dioxin and glucocorticoid receptors have previously been shown to...
