Abstract
Subsequently to the publication of the above article, an interested reader drew to the authors' attention that, in Fig. 1D on p. 1134, the data panels showing the results for the 'Control' and '1 μmol/l GW9662' experiments (on the left hand side of the figure) were overlapping, such that these data had been derived from the same original source where they were intended to show the results from differently performed experiments. The authors were able to re‑examine their original data, and realize that the data for the '1 μmol/l GW9662' panel had been selected incorrectly. The corrected version of Fig. 1, now featuring the correct data for the '1 μmol/l GW9662' experiment in Fig. 1D, is shown on the next page, The authors confirm their error did not grossly affect either the results of the conclusions reported in the paper, and are grateful to the Editor of International Journal of Oncology for allowing them this opportunity to publish a Corrigendum. They also apologize to the readership for any inconvenience caused. [International Journal of Oncology 46: 1131-1140, 2015; DOI: 10.3892/ijo.2015.2829].
