Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that the TUNEL assay data shown in Fig. 6C were strikingly similar to images that had already appeared in Fig. 8B in another article that appeared in the journal Oncotarget [Chen W, Xu X-K, Li J-L, Kong K-K, Li H, Chen C, He J, Wang F, Li P, Ge X-S and Li F-C: MALAT1 is a prognostic factor in glioblastoma multiforme and induces chemoresistance to temozolomide through suppressing miR-203 and promoting thymidylate synthase expression. Oncotarget 8: 22783-22799, 2017]. Owing to the fact that the contentious data in the above article had already been published elsewhere prior to its submission to International Journal of Oncology, the Editor has decided that this paper should be retracted from the Journal on account of a lack of confidence in the presented data. The authors did provide an explanation to account for the duplication of the data, although this was not accepted by the Editorial Board. The Editor apologizes to the readership for any inconvenience caused.
