Activation of Wnt signaling in cKit-ITD mediated transformation and imatinib sensitivity in acute myeloid leukemia.
Article in International journal of hematology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The Wnt-signaling pathway plays a critical role in directing cell fate during embryogenesis and also in the pathogenesis of cancer. In leukemia, it is well described that activating internal tandem duplications (ITD) mutations in receptor tyrosine kinases like cKit or Flt3 confer to the pathogenesis of cancer. Here, we analyzed whether Wnt-signaling plays a role in cKit-ITD mediated transformation. Stably transfected 32D cells with cKit-ITD cells had higher beta-Catenin protein levels compared to the cKit-WT. Analysis of beta-Catenin mRNA and protein levels revealed that beta-Catenin was regulated at post-transcriptional level in cKit-ITD as well as Flt3-ITD compared to the wildtype. Signaling analyses revealed higher-phosphorylation of GSK3beta by oncogenic cKit-ITD. Moreover, activation of Wnt signaling was confirmed by constitutive activation of c-myc luciferase by cKit-ITD cells. Importantly, using dominant negative TCF4, we show that activation of Wnt signaling plays an important role in cKit mediated transformation of myeloid cells. Application of specific receptor tyrosine kinase inhibitors for Flt3 or cKit result in a decrease of beta-Catenin that underwent with a decrease of GSK3beta phosphorylation, suggesting an indirect mechanism of beta-Catenin regulation by oncogenic receptor tyrosine kinases in both ITD mutations. Our study shows the importance of activation of Wnt signaling in leukemia and suggests as attractive target for future therapeutical approaches.
