The editors express a note of concern regarding the above article.
The editors wish to alert the readers that questions have been raised about the validity of some of the figures presented in this article. The questions specifically concern Figures 1B, 6A and 8A. There are indications that the molecular weight markers have been altered in Figures 1B and 6A. The background in Figure 8A suggests that the lanes might originate from different blots. We consider that this does not affect the validity of the results and the conclusions of the study, however wish to alert our readership to these concerns.
