Retraction of: Scientific Reports https://doi.org/10.1038/srep21549, published online 22 February 2016

The Editors have retracted this Article.

Two images in Fig. 3 were found to overlap with two panels in Fig. 4 of another article published earlier by different authors1. A β-catenin blot in Fig. 5e also appears to overlap with a GAPDH blot in another article also published earlier by different authors2. The Editors have therefore lost confidence in the data and conclusions of this Article.
