CORTICOSTEROIDS | Glucocorticoid Receptors
2006Corticosteroids bind to and activate a cytoplasmic glucocorticoid receptor (GR) which exists as several isoforms derived from a single gene product by alternative splicing. The activated glucocorticoid receptor translocates into the nucleus and binds to specific response elements in the promoter regions of anti-inflammatory genes such as lipocortin-1 ...

Activation of the glucocorticoid receptor*1
Journal of Molecular and Cellular Cardiology, 1982Past and ongoing approaches to the mechanism of activation of the glucocorticoid receptor have been summarized. In vivo labelling of receptors with [3H] triamcinolone acetonide at various times indicates a progression in appearance and disappearance of chromatographically separable activated and unactivated forms of steroid-receptor complexes ...

Glucocorticoid receptor regulation
Life Sciences, 1985Glucocorticoids, like other classes of steroid hormones, must bind to cellular receptors in order to exert their effects. Because of this central role in mediating hormone action, it is important to elucidate those factors that control receptor content.

Chaperoning of Glucocorticoid Receptors
2005A multiprotein hsp90/hsp70-based chaperone machinery functions as a 'cradle-to-grave' system for regulating the steroid binding, trafficking and turnover of the glucocorticoid receptor (GR). In an ATP-dependent process where hsp70 and hsp90 act as essential chaperones and Hop, hsp40, and p23 act as nonessential co-chaperones, the machinery assembles ...

Glucocorticoid receptors in ageing rats
Experimental Gerontology, 1999The role of the glucocorticoid receptor (GR) in senescence was studied in rats of increasing age. Statistically significant changes in the number of GRs from rat liver were detected, whereas the affinity for the ligand triamcinolone acetonide (TA) did not change with increasing age, and was in the range of 1-2 nM.

Xenobiotics and the Glucocorticoid Receptor
Toxicology and Applied Pharmacology, 2017Glucocorticoid Receptor (GR) is present in virtually every human cell type. Representing a nuclear receptor superfamily, GR has several different isoforms essentially acting as ligand-dependent transcription factors, regulating glucocorticoid-responsive gene expression in both a positive and a negative manner.

Glucocorticoid Receptors and Resistance to Glucocorticoids in Hematologic Malignancies
Leukemia & Lymphoma, 1994Glucocorticoids are highly effective in inducing the cytolysis of cells of lymphocytic origin. This property has resulted in their incorporation into chemotherapy regimens used in the treatment of hematologic malignancies. Studies at the molecular and cellular levels have demonstrated that the hormone-induced cytolytic response is mediated through a ...

Glucocorticoids and glucocorticoid receptors: mediators of fatigue?
Acta Neuropsychiatrica, 2003Fatigue is a common problem; when chronic and disabling, subjects can be categorized as having chronic fatigue syndrome (CFS). Whilst it is most likely a multifactorial condition of biopsychosocial origin, the nature of the pathophysiological component remains unclear.

Interaction of glucocorticoid analogues with the human glucocorticoid receptor
The Journal of Steroid Biochemistry and Molecular Biology, 1992Transient co-transfection of receptor cDNA and suitable reporter genes was used to study human glucocorticoid receptor (hGR) function in a neutral mammalian cell background. A variety of natural and synthetic steroids were analyzed for their ability to activate gene expression through the hGR and to bind to extracts of cells expressing the hGR cDNA ...

Journal of Steroid Biochemistry, 1986
Although glucocorticoid receptors have been extensively studied in a variety of tissues, the precise nature of the receptor protein still remains unknown. To further characterize this protein we assessed the effects of various lectins on [3H]dexamethasone binding to prepurified preparations of rat liver glucocorticoid receptor. Among the lectins tested
