Following the publication of the above paper, it was drawn to the Editor's attention by a concerned reader that certain of the tumour images in Fig. 3A and the immunohistochemistry data in Fig. 3C on p. 7, and colony formation assay data shown in Fig. 4F on p. 8 were strikingly similar to data that had already appeared in previous publications. Owing to the fact that the contentious data in the above article had already been published elsewhere, or were under consideration for publication, prior to its submission to International Journal of Molecular Medicine, the Editor has decided that this paper should be retracted from the Journal. After having been in contact with the authors, they accepted the decision to retract this paper. The Editor apologizes to the readership for any inconvenience caused.
