Retraction Note to: British Journal of Cancer 10.1038/sj.bjc.6605793, published online 13 July 2010
The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding high similarity between the western blot images presented in this article and the authors’ earlier publication [1]. Specifically:
Fig. 2B TS lanes 7–9 appear highly similar to Fig. 2C TS lanes 1–3 in [1];
Fig. 2B Actin 1–8 appear highly similar to Fig. 3C AKT blot in [1];
Fig. 3B Actin lanes 1–5 and 8–12 appear highly similar to Fig. 6 PC9/ZD and H1975 Actin, respectively, in [1];
Fig. 4B Actin lanes 1–5 and 8–12 appear highly similar to Fig. 6 PC9 and HCC827 Actin, respectively, in [1].
The Editor-in-Chief therefore no longer has confidence in the presented data.
