XAV-939 specifically inhibits tankyrase PARP activity. XAV-939 dramatically decreases DNA-PKcs protein levels, confirming the critical role of tankyrase poly-ADP-ribosylation activity in maintaining stability of the DNA-PKcs protein. The greatest reduction of DNA-PKcs protein levels (< 25% relative expression compared to DMSO treated controls) occurs at 12 hours with 1.0 μM XAV-939 exposure. Treatment of human lymphoblasts with 1.0 μM XAV-939 results in marked elevation of tankyrase 1 levels. [1]

XAV-939 is axin stabilizing agent. XAV-939 stimulates beta-catenin degradation by stabilizing axin, the concentration-limiting component of the destruction complex. XAV-939 stabilizes axin by blocking the poly-ADP-ribosylating enzymes tankyrase 1 and tankyrase 2. Both tankyrase isoforms interact with a highly conserved domain of axin and stimulate its degradation through the ubiquitin-proteasome pathway. XAV-939 deregulates the Wnt/b-catenin pathway which has been implicated in many cancers. [2]
Cell Research Cell lines WTK1 lymphoblasts
Concentrations 1.0 μM
Incubation Time 8 hours
Method

XAV-939 is solubilized in DMSO at 55 °C to make a 10 mM stock solution which may be diluted later to a working concentration of 100 μM. WTK1 lymphoblasts treated with either DMSO or 1.0 μM XAV-939 for 8 hours are loaded into independent wells of a 4-20% gradient SDS-PAGE every 2 hours over the course of 6 hours. At each time point, DMSO and XAV-939 samples are loaded into wells immediately adjacent to the prior time point. The corresponding load times at 0, 2 and 4 hours results in total run times of 2, 4 and 6 hours respectively. The gel is analyzed via western blot for DNA-PKcs following completion of the final run time and is quantified after normalization to actin loading controls.

Frequently Asked Questions

Question 1:
I want to inject XAV 939 (Cat # S1180) into mice through I.P. and just wonder what kind of solvent/solution I can use for this.

Answer:
S1180 XAV-939 can be dissolved in 4% DMSO+corn oil at 1 mg/ml as a clear solution. When preparing the solution, please dissolve the compound in DMSO clearly first. You can sonicate and warm it in water bath at about 45 degree to help dissolving. Then dilute with corn oil.
