  • Dexamethasone and largazole cooperate to suppress invasion and to restore E-cadherin localization to the cell peripher y. ( a) Phase contrast micrographs showing morphological changes in MDA-MB-231 cells induced by E-cadherin expression combined with 100 nM dexamethasone and 10 nM largazole treatments. Insets show the cells at higher magnification. (b ) Fluorescence (E-Cad-GFP) or immunofluorescence microscopy (g -catenin (g-Cat.)) of 231/E-Cad-GFP cells treated for 72 h with vehicle (Control), 100 n M dexamethasone, 10 nM largazole or 100 nM dexamethasone + 10 nM largazole (Dex. + Larg.). (c ) Invasion assays were per formed with the indicated cell lines treated for 72 h with or without 100 nM dexamethasone + 10 nM largazole using modified Boyden chambers impregnated with matrigel. The results are presented as the average number of cells that invaded through the membrane per field s.d. of five randomly chosen fields, and are representative of three independently per formed experiments.

    (d) BT549 cells were treated and analyzed by immunofluorescence microscopy as in Figure b. (e) BT549 cells were treated as described in Figure b and analyzed for invasion as in Figure 3c. (f) Quantitation of junctional E-cadherin staining of the indicated cell lines treated with DMSO vehicle or Dex.+ Larg. as described in Figure b. Results are presented as the mean of analyses of three different fields of cells for each sample±s.d. Statistical significance was assessed using Student’s t -test.

Biological Activity

Description Dexamethasone is a potent synthetic member of the glucocorticoid class of steroid drugs, and an interleukin receptor modulator that has anti-inflammatory and immunosuppressant effects.
Targets
interleukin receptor [1]
In vitro

Dexamethasone inhibits COX-2 mRNA expression induced by IL-1 in human articular chondrocytes. [1] 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. [2]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. [3] Dexamethasone (5 μM) treatment decreases proliferation of adult hippocampal neural progenitor cells and SRE-driven gene expression. [5]

Dexamethasone induced ER stress and activated the UPR in human TM cells. Primary human TM cells obtained from normal human donors were treated with dexamethasone for 48 hours. GRP78, GRP94, CHOP, and phosphorylation of IRE1 and eIF2α were examined by Western blot analysis (n = 3).

Dexamethasone induced bcrp, p-glycoprotein (p-gp), and mrp2 protein expression in brain endothelial cells. A: representative Western blots demonstrating the concentration-dependent increase in protein expression of bcrp, p-gp, and mrp2 in primary endothelial cells when cultured with dexamethasone for 24 h. Quantitative analysis by densitometry of three different experiments is also shown. B: dexamethasone-induced increase in bcrp, p-gp, and mrp2 expression after incubation of endothelial cells with 250 nM dexamethasone was dependent on the time of exposure. Quantitative analysis by densitometry of three different experiments is also shown. *P < 0.05 vs. untreated cells, **P < 0.01 vs. untreated cells.

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. [4] 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. [5]

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
