This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the authors, with the approval of the Editor-in-Chief. The journal was initially contacted by the corresponding author to report the unavailability of the raw data of the results presented by the article, as well as the similarity between the Western blots from Figure 11A (MMP-3) and Figure 11C (MMP-3). Also, a significant amount of text has been reused from the articles that the authors have previously published in the Experimental Cell Research 341 (2016) 92-104 https://doi.org/10.1016/j.yexcr.2016.01.010 and the Journal of Biological Chemistry 289 (2014) 14380-14391 https://doi.org/10.1074/jbc.M113.526772. All of the authors except Nobuaki Ozeki and Taiki Hiyama have reportedly agreed to retract the article. N. Ozeki left Aichi Gakuin University in March 2018 and does not respond to co-authors inquiries, while T. Hiyama left Aichi Gakuin University and could not be reached. The authors deeply regret this error and any inconvenience it may have caused.
