Studies in humans and rats suggest that intrauterine growth retardation (IUGR) permanently resets the hypothalamic-pituitary-adrenal (HPA) axis. HPA axis reprogramming may involve persistently altered expression of the hippocampal glucocorticoid receptor (hpGR), an important regulator of HPA axis reactivity. Persistent alteration of gene expression, long after the inciting event, is thought to ...
Two newly identified, overlapping (1 bp) glucocorticoid response elements (GREs) at -759 and -773 bp in the promoter of the rat phenylethanolamine N-methyltransferase (PNMT; EC 2.1.1.28) gene are primarily responsible for its glucocorticoid sensitivity, rather than the originally identified -533-bp GRE. A dose-dependent increase in PNMT promoter activity was observed in RS1 cells transfected wi...
Differential recruitment of glucocorticoid receptor phospho-isoforms to glucocorticoid-induced genes
Hydrocortisone stimulates proliferation and System A amino acid transport in cultured human fibroblasts, while decreasing production of collagen. Fibroblasts isolated from keloid tissue have an unusual glucocorticoid response; they are hyporesponsive with regard to proliferation and collagen production but hyperresponsive with regard to the induction of System A amino acid transport (Russell, J...
This review describes current knowledge on the mechanisms that underlie glucocorticoid insufficiency in sepsis and the molecular action of glucocorticoids. In patients with severe sepsis, numerous factors predispose to glucocorticoid insufficiency, including drugs, coagulation disorders and inflammatory mediators. These factors may compromise the hypothalamic-pituitary axis (i.e. secondary adre...
