The cytoplasmic and nuclear proteins were separated and the protein expression levels were determined by performing western blotting. LY364947 (1 uM), which is a potent ATP-competitive inhibitor of TGF-βRI, was used as the positive control. GAPDH and PARP were used as cytosolic and nuclear markers, respectively.

Suppression of phosphorylated (p-)SMAD family member 2 (Smad2) signaling by LY364947 reverses the inductive effect of jumonji AT-rich interactive domain 1B (JARID1B) on the expression of glioma cancer stem cell-related markers. The expression of transforming growth factor-β1 (TGF-β1), p-Smad2, Smad2, CD133, octamer-binding transcription factor 4 (Oct4), nestin and BMI1 proto-oncogene, polycomb ring finger (Bmi-1) protein levels in LY364947-exposed U251-pBabe-JARID1B and its control cells were measured by western blot analysis. β-actin was used as the internal control for western blot analysis.

LY364947 is an ATP competitive and tight-binding inhibitor, inhibiting phosphorylation of P-Smad3 by TGFβR-I kinase with Ki of 28 nM. LY364947 inhibits in vivo Smad2 phosphorylation within the NMuMg cells with IC50 of 135 nM. LY364947 reverses TGF-β-mediated growth inhibition in NMuMg cells with IC50 of 0.218 μM. LY364947 potentiates the xVent2-lux BMP4 response in NMuMg cells by 30% at concentrations as low as 0.25 μM. LY364947 (2 μM) prevents TGF-β-induced epithelial−mesenchymal transition in NMuMg cells.  LY364947 (3 μM) induces expression of Prox1 and LYVE-1 in almost all HDLECs after 24 hours.  LY364947 promotes nuclear export of Foxo3a, with low Smad2/3 and high Akt phosphorylation levels in leukaemia-initiating cells. LY364947 (< 20 μM) suppresses leukaemia-initiating cells colony-forming ability after co-culture with OP-9 stromal cells. 
|In vivo||LY364947 (1 mg/kg i.p.) accelerates lymphangiogenesis, as evidence by significantly increased the LYVE-1-positive areas, in a mouse model of chronic peritonitis. LY364947 (1 mg/kg i.p.) significantly increases the LYVE-1-positive areas in tumor tissues in tumor xenograft models using BxPC3 pancreatic adenocarcinoma cells.  LY364947 (25 mg /kg) increases p-Akt and decreases nuclear Foxo3a in leukaemia-initiating cells in CML-affected mice. |
Filter-binding assay:The IC50 of LY364947 at different enzyme concentrations are determined by the filter-binding assay. Typically, 40 μL reactions in 50 mM HEPES at pH 7.5, 1 mM NaF, 200 μM pKSmad3(−3), and 50 mM ATP containing a titration of each inhibitor with concentrations of 1600, 800, 400, 200, 100, 50, 25, and 0 nM are incubated at 30 °C for 30 min. The IC50 is calculated using a nonlinear regression method with GraphPad Prism software. The binding type is determined by plotting the correlation between enzyme concentrations and IC50 values.

* 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.
