EXPRESSION OF CONCERN: Role of the Nrf2-ARE Pathway in Early Brain Injury After Experimental Subarachnoid Hemorrhage

EXPRESSION OF CONCERN: G. Chen, Q. Fang, J. Zhang, D. Zhou, and Z. Wang, “Role of the Nrf2-ARE Pathway in Early Brain Injury After Experimental Subarachnoid Hemorrhage,” Journal of Neuroscience Research 89, no. 4 (2011): 515–523, https://doi.org/10.1002/jnr.22577.

This Expression of Concern is for the above article, published online on 21 January 2011, in Wiley Online Library (http://onlinelibrary.wiley.com/), and has been issued by agreement between the journal Editors-in-Chief, Cristina A. Ghiani and J. Paula Warrington, and Wiley Periodicals LLC. The publisher received a report from a third party who indicated that the images in Figures 4A and 4B had been re-used from Figures 9A and 9B in a previously published article by most of the same authors (Zhang et al. 2010 [https://doi.org/10.1016/j.cyto.2010.08.011]). The authors did not respond to an inquiry by the publisher and therefore did not provide original data for examination. The Expression of Concern has been agreed because the evidence of inappropriate and undeclared image duplication calls into question the validity of the data in Figure 4. The authors did not respond to our notice regarding the Expression of Concern.
