This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the Editor-in-Chief. Panels from Figure 4A appear similar to panels from Figure 1 of the article previously published by Z. Ding, F. Xu, J. Tang, G. Li, P. Jiang, Z. Tang and H. Wu in Neoplasma 63(3) (2016) 351–361 http://www.elis.sk/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=4703&category_id=128&option=com_virtuemart&vmcchk=1&Itemid=1. One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper has not been previously published and is not under consideration for publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a misuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
