  • Loss of DUSP4 function upregulates IL-6 and IL-8 and enhances mammosphere growth. Immunoblot analysis of MDA-231 cells after treatment of 24 hours with 1 umol/L selumetinib (MEKi) or 10 umol/L SP600125 (JNKi). I, MDA-231 mammosphere formation quantitated by GelCount software 7 days after siRNA transfection. Where indicated, selumetinib (MEKi) or SP600125 (JNK1) or the combination was added to the mammosphere cultures.

    Comparative effects of inhibitors by immunofluorescence microscopy study. Confluent HC11 cells were grown on poly-L-lysine-coated glass coverslips (immunofluorescence) and on plastic plates (biochemical control) and then treated with inhibitors according to the standard procedure. Upper part: the biochemical action of the inhibitors was tested to validate the immunofluorescence results. Cellular proteins were analyzed by SDS-PAGE and the immunoblots were successively probed with anti-ADRP, anti-β-casein, and anti- β-actin antibodies and their respective HRP-conjugated secondary antibodies. Each experimental condition was performed in duplicate. Lower part: cells were fixed, permeabilized and subjected to immunofluorescence microscopy using antiserum against ADRP and TRITC-conjugated secondary antibody (red).

SP600125 is originally characterized as a selective ATP-competitive inhibitor of c-Jun N-terminal kinase JNK. In Jurkat T cells, SP600125 inhibits the phosphorylation of c-Jun with IC50 of 5 μM to 10 μM. In CD4+ cells, such as Th0 cells isolated from either human cord or peripheral blood, SP600125 blocks cell activation and differentiation and inhibits the expression of inflammatory genes COX-2, IL-2, IL-10, IFN-γ, and TNF-α, with IC50 of 5 μM to 12 μM. [1] However, later studies reveal that SP600125 also suppresses aryl hydrocarbon receptor (AhR) [2], Mps1 [3], and a panel of other serine/threonine kinases, including Aurora kinase A, FLT3, MELK, and TRKA [4]. In a mouse beta cells MIN6, SP600125 (20 μM) induces the phosphorylation of p38 MAPK and its downstream CREB-dependent promoter activation. [5] In HCT116 cells, SP600125 (20 μM) blocks the G2 phase to mitosis transition and induces endoreplication. This ability of SP600125 is independent of JNK inhibition, but due to its inhibition of CDK1-cyclin B activation upstream of Aurora A and Polo-like kinase 1. [6]

In vivo In mice, SP600125 (15 mg/kg or 30 mg/kg) significantly inhibits lipopolysaccharide (LPS)-induced TNF-α expression and anti-CD3-induced apoptosis of CD4+ CD8+ thymocytes. [1]

Protocol

Kinase Assay:[4]
+ Expand

In Vitro Kinase Assays :

The potency of SP600125 towards kinases, including MPS1, JNK, and Aurora kinase A, is determined based on the specific measurement of radioactive phosphotransfer to the substrate. For each enzyme, the absolute Km values for ATP and the specific substrate are initially determined and each assay is then run at optimized [ATP] (2·αKm) and [substrate] (5·Km) concentrations. MPS1 activity is measured using 5 nM of MPS1 recombinant protein in 50 mM HEPES pH 7.5, 2.5 mM MgCl2, 1 mM MnCl2, 1 mM DTT, 3 μM NaVO3, 2 mM β-glycerophosphate, 0.2 mg/mL BSA, 200 μM P38-βtide substrate-peptide (KRQADEEMTGYVATRWYRAE), and 8 μM ATP with 1.5 nM 33P-γ-ATP. Ten serial 1:3 dilutions (from 30 μM to 1.5 nM) of SP600125 are tested and IC50 determined.

  • Cell lines: HCT116, A2780, and U2OS cells
  • Concentrations: 0–5 μM, dissolved in 0.1% DMSO
  • Incubation Time: 72 hours
  • Method: Cells are seeded in 384 well-plates. One day after seeding, the cells are treated with SP600125 for 72 hours and the plates are then processed using a CellTiter-Glo assay. Inhibitory activity is evaluated comparing treated versus control data and IC50 value of proliferation is calculated.
