A. Li, X. Lin, X. Tan, B. Yin, W. Han, J. Zhao, J. Yuan, B. Qiang, and X. Peng, "Circadian Gene Clock Contributes to Cell Proliferation and Migration of Glioma and Is Directly Regulated by Tumor-Suppressive miR-124," FEBS Letters 587, no. 15 (2013): 2455-2460, https://doi.org/10.1016/j.febslet.2013.06.018. This Expression of Concern is for the above article, published online on 19 June 2013, in Wiley Online Library (http://onlinelibrary.wiley.com/), and has been issued by agreement between the journal Editor-in-Chief, Michael Brunner; FEBS Press; and John Wiley and Sons Ltd. A third party reported that the siNC and siCLOCK images for U87MG cells in Figure 2D shared an overlapping section. An investigation by the journal confirmed these concerns. The authors responded to an inquiry by the journal and supplied what were labeled as original data and a request for correction. The authors stated that the error in Figure 2D was caused by a mistake in the image compilation process. The journal reviewed the data provided, but they were unable to validate the experimental procedures used to generate the data. The journal reviewed the data provided, but were unable to confirm that it was acquired during the original study period. As such, the journal does not view a correction as appropriate. The Expression of Concern has been agreed to in order to inform and alert readers of the image overlap in Figure 2D. The authors disagree with the Expression of Concern.
