Following publication of the original article [1], an error was identified in the images presented in Fig. 4, specifically:

Fig. 4

MiR-34a functioned as a tumor suppressor in MIBC cells. A The effect of ectopic miR-34a expression on MIBC cell proliferation was investigated by CCK-8. The miR-34a activity was mediated by transfection with miR-34a mimics or inhibitor respectively. Data are plotted as the mean ± SEM of 3 independent experiments relative to mock treatments. The effect of ectopic miR-34a expression on MIBC cell tumorgenesis was investigated by B) colony-formation and C) sphere-formation assay. Quantitative analyses of D) colony and E) sphere numbers (mean + SEM; n = 3; *p < 0.05). F Relative miR-34a expression in xenografts; G) Photographs of tumors excised 38 days after inoculation of stably transfected cells into nude mice; Mean xenograft tumor volume H) and weight I) in nude mice groups after indicated treatment (mean + SEM; n = 3; *p < 0.05)

Furthermore, two of the primer sequences listed in the Table S1 (part of ‘Additional file 3: Supplementary materials and methods’) contained typographical errors. The sequences for HGF F and GAPDH F have been corrected in the new version of the file.

The authors provided the journal with the original data files. The corrected version of Fig. 4 is provided here. The correction does not have any effect on the results or conclusions of the paper.
