Glucocorticoids (GCs) are steroid hormones used to treat inflammatory diseases such as rheumatoid arthritis, but their clinical efficacy is hampered by development of side effects such as impaired wound healing. GCs bind the glucocorticoid receptor (GR) to mediate cellular effects. The inactive GR is held in multi-protein complex in the cytoplasm and upon ligand binding undergoes a conformational change, interacts with cytoplasmic enzymes to mediate non-genomic effects (within...

Glucocorticoids (Gc) act through the glucocorticoid receptor (GR) to regulate immunity, energy metabolism, and tissue repair. The inactive GR is held in the cytoplasm in a multi-protein complex, which upon ligand binding undergoes a conformational change. Activated GR translocates to the nucleus to regulate gene expression (over hours), but some effects occur more rapidly. Gc inhibit cell migration through an uncertain mechanism. We now show a very rapid effect, and surprising...

Glucocorticoids (Gc) are potent anti-inflammatory steroids which mediate their effects by binding the glucocorticoid receptor (GR). Following ligand binding, GR initiates rapid ‘non-genomic’ kinase signals in the cytoplasm, then translocates into the nucleus to mediate ‘genomic’ effects by binding DNA directly or tethering to other DNA bound transcription factors to modulate target gene expression. Little is known about how rapidly induced cytoplasm derived...
