has been retracted by the current and former Publishers and the Editor on behalf of the authors.
Following publication, the authors found that the U2OS cells used in this study were contaminated by HeLa cells and, as a result, they state that the findings may be incorrect. The authors have requested the retraction of the article for these reasons.
Additionally, concerns have been raised regarding images in Figures 2, 3 and 5 in the article and duplication of these images in other articles. When asked to comment on these concerns, the authors stated that a third party performed the transwell assay and in vivo studies and that they were unable to reproduce the in vivo experiment.
The article is being retracted for the above reasons.
