A reader approached us with concerns that were raised on PubPeer regarding the figures in this article. PubPeer commentors noticed that numerous Western blots appear highly similar. An Editorial assessment of the concerns raised indicated the following:

The authors deny the images are duplicated and say that the appearance of duplication may be related to the low quality of the images. The authors were unable to provide the data used for this experiment, but have explained that they are able to replicate their findings with unprocessed samples to which they still have access. However, the Journal Editors deemed their response insufficient to the original concerns raised due to their inability to access the data underlying this article.
Due to the unresolved concerns about multiple images within the article that call into question the overall integrity of the findings, the Journal Editors retract this article.
