RETRACTION: PEG2000-DPSE-Coated Quercetin Nanoparticles Remarkably Enhanced Anticancer Effects through Induced Programed Cell Death on C6 Glioma Cells

Abstract

RETRACTION: G. Wang, JJ. Wang, J. Luo, L. Wang, XL. Chen, LP. Zhang, and SQ. Jiang, “ PEG2000-DPSE-Coated Quercetin Nanoparticles Remarkably Enhanced Anticancer Effects through Induced Programed Cell Death on C6 Glioma Cells,” Journal of Biomedical Materials Research Part A 101, no. 11 (2013): 3076–3085, https://doi.org/10.1002/jbm.a.34607.

The above article, published online on 25 March 2013, in Wiley Online Library (http://onlinelibrary.wiley.com/), has been retracted by agreement between the journal Editor-in-Chief, J. Kent Leach; and Wiley Periodicals LLC. A third party reported several concerns to the publisher about duplicated images in this article, including duplication of a plot between Figures 4B and 4D; duplication of an image within Figure 4E; and duplication of all images in Figure 4E with another article published by many of the same authors (Wang, et al. 2013 [https://doi.org/10.1038/cddis.2013.242]). Further investigation by the publisher uncovered evidence of duplication, manipulation, and resizing of western blot images between Figures 5D and 5E; duplication of beta-actin bands between Figures 5C, 5D, and 6E; and insertion of a band in Figure 6E. The authors responded to an inquiry by the publisher and stated that the image duplications were the result of errors during figure preparation and labeling the original data. However, the parties agree that the explanations and data supplied by the authors did not properly address the concerns raised. The retraction has been agreed to because the evidence of image duplication and manipulation fundamentally compromises the reliability of the data and conclusions reported in this article. The authors did not respond to our notice regarding the retraction.
