Abstract
Subsequently to the publication of the above article, an interested reader drew to the authors' attention that a pair of data panels showing the results of immunohistochemical staining experiments in Fig. 1 on p. 2210 had already appeared in a previously published paper (Zhang Y, Li Y, Lin C, Ding J, Liao G and Tang B: Aberrant upregulation of 14‑3‑3σ and EZH2 expression serves as an inferior prognostic biomarker for hepatocellular carcinoma. PLos ONE 9: e107251, 2014). Owing to the fact that the contentious data in the above article had already been published prior to its submission to International Journal of Oncology, the Editor has decided that this paper should be retracted from the Journal. The authors were asked for an explanation to account for these concerns, but the Editorial Office did not receive a satisfactory reply. The Editor apologizes to the readership for any inconvenience caused. [International Journal of Oncology 47: 2208‑2216, 2015; DOI: 10.3892/ijo.2015.3214].
