Oncol Rep 27:
Following the publication of this article, an interested reader drew to the attention of the Editorial Board that the above article appeared to contain a series of Figures that featured duplicated data. Following an internal investigation, the Editorial Board reached the conclusion that the allegations of the reader were well-founded. Specifically, the GAPDH bands shown in Figs. 2 and 3 are identical with those in Figs. 4C and 5D, with the exception that the images have been reversed. Furthermore, certain data in Fig. 4C of this paper appeared to have been shared with Fig. 3 in the following article (albeit for purportedly different experiments): Zhang J, Zhu J, Zhou Z, Chen W and Chen N: Inhibitory effects of ethyl pyruvate on invasion and metastasis of human gastric cancer SGC-7901 cells via downregulation of Akt pathway. China J Cancer Prev Treat (Chin) 39: 776–779, 2012.
Despite numerous attempts at doing so, we were unable to receive any response to our request for further information from the authors of this article. Given the extent of the anomalies with the data between the aforementioned papers, the Editorial Board has therefore decided to retract the article from Oncology Reports. We regret any inconvenience in this regard.
