B. Wu, X. Wang, R. Yu, and X. Xue, "CircWHSC1 Serves as a Prognostic Biomarker and Promotes Malignant Progression of Non-Small-Cell Lung Cancer Via miR-590-5p/SOX5 Axis," Environmental Toxicology 38, no. 10 (2023): 2440-2449, https://doi.org/10.1002/tox.23879. This Expression of Concern is for the above article, published online on 7 July 2023 in Wiley Online Library (http://wileyonlinelibrary.com), and has been issued by agreement between the journal Editor-in-Chief, April Rodd; and Wiley Periodicals LLC. Following publication, concerns were raised regarding the animal experimental data and Figure 2. Discrepancies were noted because the figure shows data beyond the "4 weeks after implantation" described for euthanasia in the main text. Additionally, the authors did not respond to the publisher's request to provide the original data, the ethics approval codes, and proof of patient consent. In the absence of the original data, the journal and publisher are unable to fully investigate the discrepancies. Therefore, the journal has decided to issue an Expression of Concern to inform and alert readers.
