Canonical hedgehog transactivates HIF-1α, which mediates the angiogenic properties of HSCs. HSCs were treated with PX-478, cyclopamine or GANT-58 at indicated concentrations for 24 h (A-C） or 3 h (D). (A) Cell viability was determined using Cell Counting Kit-8. Data were expressed as percentage of control value (n = 6). *P < 0.05 versus control, non-parametric analyses with Kruskal-Wallis H test. (B, E) Real-time PCR analyses of angiogenic cytokines (B) and HIF-1α (E). Data were expressed as fold of control value (n = 6). *P < 0.05 versus control, non-parametric analyses with Kruskal-Wallis H test. (C, F) Western blot analyses of angiogenic cytokines (C) and HIF-1α (F) (n = 3). (D) Tubulogenesis assay with quantification of number of closed intercellular compartments (100× magnification) (n = 5). *P < 0.05 versus control, Student's t-test.

(A) Cell proliferation was determined using MTT assay. Significance: *P < 0.05 versus control. (B) Real-time PCR analyses of mRNA expression of CD31 and vWF. Significance: *P < 0.05 versus control. (C) Western blot analyses of protein expression of CD31 and vWF.

Following pretreatment with DMSO, PX-478 or trigonelline, NS-KD and TAK1-KD VSMCs were treated with PBS or IL-1a for 24 h. While whole cell lysates were immunoblotted with anti-C/EBPb and anti-b-actin, RNA and medium was analyzed for SDF-1 expression using qRT-PCR and ELISA.

|Description||PX-478 2HCl is an orally active, and selective hypoxia-inducible factor-1α (HIF-1α) inhibitor. Phase 1.|
PX-478 lowers HIF-1α protein levels and HIF-1 transactivation in hypoxia and in normoxia in a variety of cancer cell lines, but has a more pronounced effect on translation of proteins, such as HIF-1α in hypoxia.  PX-478 also enhances the radiosensitivity of prostate carcinoma PC3 cells. 
|In vivo||In HT-29 human colon cancer xenografts, PX-478 suppresses HIF-1alpha levels and inhibits the expression of HIF-1 target genes including vascular endothelial growth factor and the glucose transporter-1. In addition, PX-478 (100 or 120 mg/kg i.p.) also shows antitumor activity including cures against several established human tumor xenografts that is related to the levels of HIF-1α.  In high-fat-diet mice, PX-478 causes reduced fibrosis and fewer inflammatory infiltrates in their adipose tissues. |

* 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.
