Following the publication of this article, a concerned reader drew to the authors' attention that a pair of the 24 h scratch-wound assay data panels in Fig. 4A, and three of the migration and invasion assay data panels in Fig. 4B, exhibited overlapping sections, suggesting that data which were intended to have shown the results from differently performed experiments had originated from the same sources. In addition, the total number of cases for the LSCC sample data in Table II did not reflect the sum of the samples indicated in the ‘negative’, ‘positive’ and ‘strong positive’ categories.

After having consulted their original data, the authors have realized that Table II and Fig. 4 contained some inadvertent errors: The authors divided their control group data into two subgroups, namely the non-transfection and negative-shRNA groups, although they overlooked details of the filing system they had devised for saving the data, and mistakenly included images from the non-transfection group in with the negative-shRNA group due to unclear file labeling. Moreover, in Table II, the data value for the ‘positive’ stained samples should have been written as ‘43’, not ‘44’.

The corrected versions of Table II and Fig. 4, which now shows the corrected data for the ‘Negative-shRNA / 24 h’ experiment in Fig. 4A and the ‘Non-transfection / Invasion’ and ‘Negative-shRNA / Migration’ experiments in Fig. 4B, are shown below and on the next page, respectively. The authors sincerely apologize for the errors that were introduced during the preparation of this table and this figure, thank the Editor of Oncology Reports for granting them the opportunity to publish this corrigendum, and regret any inconvenience that these mistakes may have caused to the readership.
