Abstract

This article has been retracted: please see Elsevier Policy on Article Withdrawal ( http://www.elsevier.com/locate/withdrawalpolicy ). This article has been retracted at the request of the authors and the Editor in Chief. Several months after the publication of this article, two of the corresponding authors, Peng Zhang and Ge-Ning Jiang, contacted the publisher to request that their names be removed from the article. Drs. Zhang and Jiang stated that they were not involved in the preparation of the manuscript and did not consent to its submission and subsequent publication. Further investigation revealed that the email addresses used for correspondence during the submission and review process for Drs. Zhang and Jiang were changed during the proofing process, indicating potential authorship fraud. Image analysis of the manuscript revealed evidence of image duplication in identical or altered fashion in Figures 1E, 1J, 2H, 3H, 3I, 3K, 4D, and S5D. This reuse (and in part, misrepresentation) of data without appropriate attribution represents a severe abuse of the scientific publishing system.
