CsA and FTY720 suppress HFD-induced hepatic fat accumulation. Mice were sacrificed at the end of experiment and liver samples were freshly collected and processed. (a) Representative images of liver samples with H&E staining. (b) Representative images of liver samples with Oil Red O staining. Scale bars represent 100 µm.
Pharm Res, 2016, 33(2):395-403. Cyclosporin A purchased from Selleck.
Repression of BSEP gene expression upon treatment with reported BSEP inhibitors in human primary hepatocytes. BSEP mRNA expression was measured using real-time PCR in hepatocytes from at least three donors upon treatment with BSEP inhibitors as described under Materials and Methods. All the data are expressed as mean ?S.D. (n = 3).

Immunophilins participate in SOCE activation by CN-dependent but also CN-independent signaling pathways. Fura-2 loaded platelets were suspended in HBS, platelets are incubated for 5 min with cyclosporin A (CsA, 50 µM). Once incubation time was over, platelets were stimulated with TG (200 nM) in a calcium free-HBS (EGTA 100 μM was added as indicated the by arrowhead) and 4 min later CaCl2 (300 µM) was added to visualized calcium entry. Changes in fura-2 fluorescence were monitored using the 340/380nm ratio and calibrated in terms of [Ca2+]c . Traces are representative of four to six independent experiments. *,**, *** represents p < 0.05, p < 0.01 and p <0.001, respect control platelets.

|Description||Cyclosporin A is an immunosuppressive agent, binds to the cyclophilin and then inhibits calcineurin with IC50 of 7 nM in a cell-free assay, widely used in organ transplantation to prevent rejection.|
Cyclosporin A binds to the cyclophilin (immunophilin) in T cells , forms a Cyclophilin-Cyclosporin A complex which the binds to and inhibits calcineurin.  Cyclosporin A inhibits calcineurin with IC50 of 7 nM, then blocks the nuclear translocation of NF-AT.  Cyclosporin A also affects mitochondria by preventing the MTP (mitochondrial permeability transition pore) from opening with an IC50 of 39 nM. 
|In vivo||Cyclosporin A is an immunosuppressive agent that is effective following either parenteral or oral administration in mice, rat and guinea pigs. , is clinically used in organ transplantation to prevent rejection. |
Phosphatase Assay:Purified bovine brain calcineurin and calmodulin are purchased. Reaction mixtures with purified enzyme contains 100 nM calcineurin, 100 nM calmodulin, and 5 μM 32P-labeled phosphopeptide, in 60 μl (total volume) of assay buffer containing 20 mM Tris (pH 8), 100 mM NaCI, 6 mM MgCl2, 0.5 mM dithiothreitol, 0.1 mg of bovine serum albumin per ml, and either 0.1 mM CaCl2 or 5 mM EGTA. Reaction mixtures with cell lysates contains 20 μl of undiluted lysate, 5 μM 32P-labeled phosphopeptide, and 40 μl of assay buffer. Where indicated, reaction mixtures contains 50 μM peptide 412 or 413 and/or 500 nM okadaic acid, a specific inhibitor of phosphatases 1 and 2A; 500 nM okadaic acid is sufficient for inhibition of Ca2+-independent phosphatases, whereas higher concentrations partially inhibit Ca2+-dependent activity as well. After 15 min at 30°C, reactions are terminated by the addition of 0.5 ml of 100 mM potassium phosphate buffer (pH 7.0) containing 5% trichloroacetic acid. Free inorganic phosphate is isolated by Dowex cation-exchange chromatography and quantitated by scintillation counting as described.

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 (g) = Concentration (mol/L) × Volume (L) × 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.
