Following publication, concerns were raised about image duplication within Figure 4A. The authors provided the available original data for the article on request. A review of this data raised further concerns about the data presented in the result. The authors state that due to the time elapsed since the experiments and the unavailability of some of the original data, they are not able to address these concerns. As concerns were identified in the available data underlying the article that can not be addressed, the reliability of the findings presented in the article can not be guaranteed and the article is being retracted.

The corresponding author agreed with this retraction on behalf of all authors and stated that the authors plan to repeat the experiments where data has been lost.
