  • Western blots of nuclear and cytoplasmic fractions of β-catenin and total CDH3. d The ratio of nuclear/cytosolic of β-catenin was calculated by densitometry analysis.

    Lab Invest, 2018, 98(12):1527-1537. SKL2001 purchased from Selleck.

    A549 cells were treated with SKL2001 for 15 h, cell lysates were collected for western blotting, concentration gradient (1, 10 μM, 20 μM) was set for the analysis.

  • (D) Overexpression of CASC2 suppressed the protein expression of β-catenin, Cyclin-D1, and c-Myc in U251 cells and the effect could be reversed by SKL2001. (E) CASC2 overexpression restrained the proliferation, migration, and invasion capacity in U251 cells and SKL2001 could reverse the effect of CASC2.

Biological Activity

Description SKL2001 is a novel agonist of the Wnt/β-catenin pathway. It disrupts the Axin/β-catenin interaction.
Wnt/β-catenin [1]
(Cell-free assay)
In vitro

SKL2001 upregulated β-catenin responsive transcription by increasing the intracellular β-catenin protein level and inhibited the phosphorylation of β-catenin at residues Ser33/37/Thr41 and Ser45, which would mark it for proteasomal degradation, without affecting CK1 and GSK-3β enzyme activities. SKL2001 disrupted the Axin/β-catenin interaction, which is a critical step for CK1- and GSK-3β-mediated phosphorylation of β-catenin at Ser33/37/Thr41 and Ser45. The treatment of mesenchymal stem cells with SKL2001 promoted osteoblastogenesis and suppressed adipocyte differentiation, both of which were accompanied by the activation of Wnt/β-catenin pathway. SKL2001 did not affect either NF-κB or p53 reporter activity and inhibits β-catenin phosphorylation without affecting GSK-3β activity[1].

  • Cell lines: HEK293 reporter and control cell lines
  • Concentrations: 20 μM
  • Incubation Time: 15 h
  • Method: The HEK293 reporter and control cell lines were established. The HEK293 reporter cells were inoculated into 384-well plates at 10 000 cells per well and grown for 24 h. Next, each compound in the chemical library (∼270 000) was added to at a final concentration of 20 μM. After 15 h, the plates were assayed for firefly luciferase activity.

Bio Calculators

Molarity Calculator

Molarity Calculator

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)

  • Mass
    Molecular Weight

*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).

Dilution Calculator

Dilution Calculator

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 )

  • C1

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.
