Abstract
Following the publication of this article, an interested reader drew to our attention that three errors had occurred in the layout of the figures. In the initial and published version of Fig. 3A and B, the pictures from the Normal 0 h and Vector 0 h group were derived from the same original source due to the errors in our naming system. When the pictures were captured, these were erroneously named as 'control 1/control 2', and not 'normal/vector.' Also, in the published version of Fig. 7C, the protein expression levels of extracellular-signal-regulated kinase (ERK) and β-actin in the MB231 cells were wrongly presented. Essentially, the band of β-actin was a duplication of ERK. After having re-examined our original data, we realize that the Figure was compiled incorrectly, and have returned to our source data. Corrected versions of Figs. 3 and 7 are presented below. These errors did not affect the overall conclusions reported in the present study. We sincerely apologize for our mistake, and thank the reader of our article who drew this matter to our attention. Furthermore, we regret any inconvenience these mistakes have caused.
