General description

A cell-permeable synthetic steroid that acts as a potent antagonist of progesterone and glucocorticoid receptors. Inhibits P-glycoprotein (P-gp) function and down-modulates P-gp mediated drug resistance. Displays anti-angiogenic effects and suppresses vascular endothelial growth factor (VEGF) production. Regulates the expression of Fas and FasL in mouse endometrium and TRAIL in prostate cancer cells. As an antioxidant, it offers neuroprotection against controlled cortical impact (CCI) in CA1 pyramidal cells, as well as Aβ-, H2O2-, and glutamate-induced injury to mouse hippocampal HT22 cells.
A cell-permeable, synthetic steroid that acts as a potent antagonist of progesterone and glucocorticoid receptors. Reported to inhibit P-glycoprotein (P-gp) function and down-modulate P-gp mediated drug resistance. Also displays anti-angiogenic effects and suppresses vascular endothelial growth factor (VEGF) production. Shown to regulate the expression of Fas and FasL in mouse endometrium and of TRAIL in prostate cancer cells. As an antioxidant, it is reported to offer neuroprotection against controlled cortical impact (CCI) in CA1 pyramidal cells, as well as Aβ-, H2O2-, and glutamate-induced injury to mouse hippocampal HT22 cells.

In healthy adult organs, robust feedback mechanisms control cell turnover to enforce homeostatic equilibrium between cell division and death [1, 2]. Nascent tumors must subvert these mechanisms to achieve cancerous overgrowth [3-7]. Elucidating the nature of this subversion can reveal

Adipocytes are critical cornerstones of energy metabolism. While obesity-induced adipocyte dysfunction is associated with insulin resistance and systemic metabolic disturbances, adipogenesis, the formation of new adipocytes and healthy adipose tissue expansion are associated with metabolic benefits.

Lipid digestion and absorption are tightly regulated to cope with metabolic demands among tissues. How these processes are coordinated is not well characterized. Here, we found that mifepristone (RU486) prevents lipid digestion both in flies and mice. In flies, RU486

Responding to different dynamic levels of stress is critical for mammalian survival. Disruption of mineralocorticoid receptor (MR) and glucocorticoid receptor (GR) signaling is proposed to underlie hypothalamic-pituitary-adrenal (HPA) axis dysregulation observed in stress-related psychiatric disorders. In this study, we show
