This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). This article has been retracted at the request of the Editor-in-Chief. Concerns raised by Dr. Sander Kersten in PubPeer pointed out that Figures 6.1B and 6.2B of this paper were different figures but the legends and Western blots were identical; the quantification was also seen to be different between the two figures. Shortly afterwards, the authors asked to publish a corrigendum for part B of Figure 6.1, including images of western blots and associated bar plots. Subsequently, the journal conducted an investigation and found evidence that there had been improper manipulation and duplication of images in Figures 2 E, 6.2 B, 5 A and and 6.2 D, as shown by the reuse of several western blot bands with approximately 180° rotation in each case. After raising the complaint with the authors, the corresponding author agreed that the paper should be retracted. The authors apologise to the readers of the journal.
