The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding suspected image overlap with three other articles [1-3]. Specifically, in Fig. 2d, all subpanels appear to be highly similar to the images in Fig. 3c (rotated) in [1]. In Fig. 2f, a number of images appear highly similar to those in Figs. 5a and c in ([2], now retracted) and 3e in [3]. In addition, Fig. 5e appears to be drawn by hand.

The authors have provided the original data and revised figures to address the concerns. However, the original data contains highly similar backgrounds in the western blot gel photographs. Additionally, the source, number and sex of animals are different between the Ethics approval document and the Methods section of the article.

The Editor-in-Chief therefore no longer has confidence in the presented data and the ethical standards of the study.

Hui Cao agrees to this retraction. Mingli Han and Huaying Dong have stated on behalf of all co-authors that they agree to this retraction.
