Abstract
Following the publication of the above article, an interested reader drew to the author's attention that Fig. 4 contained a duplication error, which arose during the assembly of the figure; specifically, the upper-left panel in Fig. 4, showing the result of the 'Control in 12 h' experiment, was inadvertently repeated with the 'Control in 48 h' panel. The corrected version of Fig. 4, showing the correct data for the 'Control in 12 h' experiment, is shown below. The authors can confirm that this error does not change either the interpretation or the original conclusions of this study. The authors are grateful to the Editor of International Journal of Molecular Medicine for granting them the opportunity to publish the Corrigendum, and all the authors agree with this correction. Furthermore, the authors apologize to the readership for any inconvenience caused.
