Chronic excessive activation of glucocorticoid receptors induces obesity, insulin resistance, glucose intolerance, dyslipidaemia and hypertension. Subtle abnormalities of the hypothalamic-pituitary-adrenal axis and/or of tissue sensitivity to glucocorticoids are also associated with these cardiovascular risk factors in patients with the metabolic syndrome. Furthermore, glucocorticoids have dire...

Menopause involves dramatic declines in estradiol production and levels. Importantly, estradiol and the class of stress hormones known as glucocorticoids exert countervailing effects throughout the body, with estradiol exerting positive effects on the brain and cognition, glucocorticoids exerting negative effects on the brain and cognition, and estradiol able to mitigate negative effects of glu...

Glucocorticoids have a bimodal effect on cognition, hippocampal pyramidal neurons and long-term potentiation (LTP). Transient increases in glucocorticoids improve performance at spatial memory tasks and facilitate synaptic efficacy, depending on the context. On the other hand, long-term elevations of glucocorticoids are associated with decreased cognitive performance, attenuated synaptic effica...

Glucocorticoids are among the most commonly used anti-inflammatory agents. Despite the enormous efforts in elucidating the glucocorticoid-mediated anti-inflammatory actions, how glucocorticoids tightly control overactive inflammatory response is not fully understood. Here we show that glucocorticoids suppress bacteria-induced inflammation by enhancing IRAK-M, a central negative regulator of Tol...

BACKGROUND Methylprednisolone, dexamethasone, and other glucocorticoids have been found effective against nausea and vomiting induced by chemotherapy and surgery. Although the specific 5-hydroxytriptamine3 (5-HT3) receptor antagonists such as ondansetron and ramosetron are used as antiemetics, reports show that the use of 5-HT3 receptor antagonists with some glucocorticoids brings additional ef...

Glucocorticoids are the first-line treatment option for pemphigus. Moreover, abnormal uterine bleeding (AUB) is a rarely reported side effect of glucocorticoid treatment that usually manifests as abnormal and excessive endometrial bleeding; in fact, AUB can be induced by the systemic or topical application of glucocorticoids. In the present report, we describe the cases of 3 patients with pemph...

Glucocorticoids rapidly induce transcription from the mouse mammary tumour virus (MMTV) promoter via a glucocorticoid receptor (GR)-mediated chromatin disruption event. This remodelling of chromatin is transient such that upon prolonged exposure to hormone the promoter becomes refractory to glucocorticoids. We demonstrate that this refractory state requires the continual presence of hormone and...

Glucocorticoid administration to mice results in a rapid loss of bone mineral density due to an imbalance in osteoblast and osteoclast numbers. Whereas excess glucocorticoids reduce both osteoblast and osteoclast precursors, cancellous osteoclast number surprisingly does not decrease as does osteoblast number, presumably due to the ability of glucocorticoids to promote osteoclast life span. Whe...
