Abstract
An interested reader drew to our attention that, in the above-mentioned article, there were two figures where identity in certain of the data was shared between panels within the same figure. First, in Fig. 3B, the data shown for the EC9706 cell line/negative control (NC) experiment were derived from the same original source as those for the EC-1/Blank control experiment. Secondly, in Fig. 6B the Bcl-2 bands for the two different cell lines, EC9706 and EC-1, were inadvertently duplicated (the data shown for the EC9706 cell line were correct). We have reviewed the original files and the individual figures for the submitted composite figures, and realize that the errors occurred when we produced the composite figures. The same images were accidentally inserted twice in Figs. 3 and 6 without us being fully aware of the error. We have identified all the original images, and the corrected versions of Figs. 3 and 6 are shown opposite. We regret that these errors went unnoticed prior to publication, and thank the Editor for affording us the opportunity to publish this Corrigendum. We also regret any inconvenience caused to the readership of the journal. [the original article was published in the International Journal of Oncology 46: 2163-2171, 2015; DOI: 10.3892/ijo.2015.2900].
