Concerns have been raised about the western blot bands presented in Figures 2A and 4A of this article (Li et al., 2013; doi: 10.3969/j.issn.1673-5374.2013.30.006).
Figure 2A appears to include splicing between lanes 1 and 2 in Bcl-2 blots in the valproic acid group.
Figure 4A appears to include splicing between lanes 1 and 2, 4 and 5, 5 and 6 in c-Jun blots in the injury group.
The corresponding author has stated there was an error in the selection of blot images used for Figures 2A and 4A.
The Neural Regeneration Research Editors have been unable to verify the accuracy and reliability of the western blot data presented in the paper. In light of the extent of the unavailability of the underlying original western blot data and the unresolved concerns regarding the accuracy and reliability of the figures, the Neural Regeneration Research Editors retract this article.
All authors agreed with the retraction.
