Retraction to: British Journal of Cancer 10.1038/bjc.2016.244, published online 18 August 2016
The Editor-in-Chief has retracted this article because of significant concerns regarding a number of Figures presented in this work, which question the integrity of the data. Figures 3F, 4G, 5C, 5D, and 5H appear to contain multiple duplicated panels. The Editor-in-Chief therefore no longer has confidence in the integrity of the data in this article. Xiang-Ling Wang and Zhen Yang agree to this retraction. Ru Bai, Wei-Ying Liu, Xin Li, Min Liu and Hua Tang did not respond to correspondence from the Editor about this retraction.
