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.

Effect of SENP2 overexpression on apoptosis-related proteins in CLL cells with or without dexamethasone treatment. (A and B) MEC2 cells in which SENP2 was overexpressed and the control cells were cultured in 6 cm dishes and then treated with dexamethasone for 24 h after reaching 70% confluence. Western blot analysis was then performed to inspect the expression levels of cleaved caspase-9, caspase-9, cleaved caspase-3, caspase-3, c-Myc, p53, Bax and Bcl-2 in these cells. GAPDH was used to confirm equal amount of proteins loaded in each lane. CLL, chronic lymphocytic leukemia; NC-OE-SENP2, MEC2 cells transfected with null (control) overexpression vector; OE-SENP2, MEC2 cells transfected with SENP2 overexpression vector; NC-shRNA-SENP2, MEC2 cells transfected with null control shRNA; shRNA-SENP2, MEC2 cells transfected with shRNA against SENP2; +, dexamethasone treatment, −, no dexamethasone treatment.

|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.|
Dexamethasone results in decrease in transmonolayer paracellular permeability mainly to sucrose, fluorescein and dextrans of up to 20 KDa in an immortalised rat brain endothelial cell line (GPNT). Dexamethasone results in filamentous actin and the cytoskeleton associated protein cortactin being highly concentrated in the regions of cell-cell contact with few F-actin stress fibres visible within the cytoplasm in cultured rat brain endothelial cells, an observation consistent with a more differentiated barrier phenotype induced by dexamethasone. Dexamethasone treatment has been shown to strongly stimulate the level of the Id-1 protein, which is a serum-inducible helix-loop-helix transcriptional repressor, involved in cell differentiation, and this effect was shown to be associated with reorganisation of ZO-1 to the cell periphery in Con8 mammary epithelial tumor cells. Dexamethasone prevents cytokine-induced enhanced expression of MMP-9 and alterations in the expression of ZO-1 in untreated GPNT monolayers.  Dexamethasone depletes both basal and TNF-alpha-stimulated GSH levels by down-regulating the gamma-GCS-heavy subunit transcription via a mechanism involving AP-1 (c-Jun) in alveolar epithelial cells. Dexamethasone decreases both basal and stimulated GSH levels (TNF-α-treated) in alveolar epithelial cells (A549), without any change in GSSG. 
|In vivo||Dexamethasone is administered i.m. to pregnant ewes, leads to the following results (1) blood pressure is unchanged; (2) as previously reported in the fetus, sensitivity to endothelin-1 (ET) is increased; (3) acetylcholine-induced relaxation is increased; (4) L-NAME suppressible vasodilatory response to ET is abolished; (5) there is no change in endothelium-independent vasodilatation; and (6) there is no change in eNOS RNA and protein levels, when compared to saline treated controls. |

For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

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.

Frequently Asked Questions
I'm loonkig for Dexamethasone to use in cell culture, would it be better to use the Dexamethasone S1322, the sodiume phosphate S4028 or the acetate S3124?
S1322 is the free base form of Dexamethasone, S4028 is the sodium phosphate form and S3124 is the acetate salt. All of them have similar biological activity in tissue culture, however, their suitabilities vary in different solvents. As free base, S1322 has high solubility in DMSO (79mg/ml), poor solubility in water (<1mg/ml), and moderate solubility in ethanol (6mg/ml). As sodium phosphate salt, S4028 has high solubility in water (103mg/ml) but is insoluble in DMSO and ethanol (<1mg/ml). The solubility of S3124 is 87mg/ml in DMSO, <1mg/ml in water, and 20mg/ml in ethanol. Selection can be made based on the customer's experimental setup.
