| In Vitro | In vitro activity: Dexamethasone inhibits COX-2 mRNA expression induced by IL-1 in human articular chondrocytes. Dexamethasone suppresses the cyclooxygenase-2 induction by tumor necrosis factor α (TNFα) with an IC50 of 1 nM in MC3T3-E1 cells. Dexamethasone binds to the glucocorticoid receptor and then to the glucocorticoid response element. Dexamethasone (10 μM) induces osteoblastic differentiation of rat bone marrow stromal cell cultures with elevated mRNA expression of alkaline phosphatase osteopontin, bone sialoprotein, and osteocalcin. Dexamethasone (5 μM) treatment decreases proliferation of adult hippocampal neural progenitor cells and SRE-driven gene expression. |

| In Vivo | Dexamethasone (2 mg/kg) reduces the number of the BrdU-labeled hepatocytes by 80% in male Fischer F344 rats. Dexamethasone (2 mg/kg) pretreatment suppresses the expression of both TNF and IL-6 after partial hepatectomy and significantly reduces the proliferative response of the hepatocytes in male Fischer F344 rats. Dexamethasone also severely diminishes the induction and expansion of oval cells induced by the 2-acetylaminofluorene/partial hepatectomy (AAF/PH) protocol but does not have any effect on the proliferation of the bile duct cells stimulated by bile duct ligation. Dexamethasone (100 μg/kg) produces a significant decrease 59.2% of BrdU(+) hippocampal progenitor cells in Sprague–Dawley rats. Dexamethasone (100 μg/kg) decreases ERK activation in granule cell layer in Sprague–Dawley rats. |
