  • Autophagosomal inhibition was performed in 32D EV, WT CALR, del52, and ins5 expressing cells. The 32D cell lines were treated with the inhibitor spautin-1 for the indicated time. Lysates were prepared, and SDS-PAGE and Western blotting were performed. Antibodies detecting mutated CALR (CALR mut), CALR, LC3I-II, and GAPDH were used for immunostaining. LC3I-II served as control for successful autophagosomal inhibition.

    (c) PC-9G cells were treated with BIBW2992 (250 nM) or WZ4002 (15 nM) plus SAHA (2 mM) with or without spautin-1 (20 mM) for 24 hr. The cell lysates were harvested and the indicated proteins were analyzed by Western blotting.

Biological Activity

Description Spautin-1 is a potent and specific autophagy inhibitor, and inhibits the deubiquitinating activity of USP10 and USP13 with IC50 of ∼0.6-0.7 μM.

USP13 [1]

In vitro

In Bcap-37 cells, Spautin-1 dramatically enhanced cell death in glucose-free media and induces apoptotic morphology. In Bax-Bak DKO cells, spautin-1 inhibits etoposide induced autophagic cell death. Spautin-1 promots the degradation of Vps34 complexes by regulating the deubiquitination activity of USP10 and USP13, and reduces the levels of PtdIns3P. [1] In PDGF-treated cells, spautin-1 stabilizes α-smooth muscle cell actin and calponin, prevents actin filament disorganization, diminishes production of extracellular matrix, and abrogates VSMC hyperproliferation and migration. [2] In CML cells, spautin-1 markedly inhibits IM-induced autophagy by downregulating Beclin-1, and enhances IM-induced apoptosis by inactivating PI3K/AKT and activating downstream GSK3β. [3] Spautin-1 also specifically reduces infectious dengue virus titers in BHK-21 cells. [4]

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)

*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

* 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.
