The Editor-in-Chief has retracted this article. Concerns were raised regarding Figure 4B: the LN229 and U251 ZEB2 bands appear to be identical but flipped horizontally. Additionally, the authors have been unable to provide convincing documentation that ethics approval was obtained for this study. The Editor-in-Chief therefore no longer have confidence in the results and conclusions of this article.
Author Shuang Feng disagrees with this retraction. The other authors have not responded to correspondence regarding this retraction.
