The publisher regrets errors were introduced in Fig. 3 A of the article described above. The images for both p-Scramble and p-miR-34b/c in SBC5 were incorrect. An amended version of Fig. 3 is shown below. Note that the analyses for both migration and invasion assays were appropriate and thus it is not necessary to correct the bar graphs in Fig. 3 as well as the legends for Fig. 3. The authors also consider that there is no need to correct any other parts of this article. The publisher would like to apologise for any inconvenience caused.
