J. Zhou, G. Song, M. Su, H. Zhang, T. Yang, and Z. Song, "Long Noncoding RNA CASC9 Promotes Pancreatic Cancer Progression by Acting as a ceRNA of miR-497-5p to Upregulate Expression of CCND1," Environmental Toxicology 38, no. 6 (2023): 1251-1264, https://doi.org/10.1002/tox.23761. The above article, published online on 22 March 2023, in Wiley Online Library (http://onlinelibrary.wiley.com/), has been retracted by agreement between the journal Editor-in-Chief, April Rodd; and Wiley Periodicals LLC. Following publication, duplications were noted in Figures 6G; in multiple panels within Figures 6F and 5O; in multiple panels between Figures 2D and 5O; and between Figures 4J and 5O. Additionally, the western blots in Figure 6H were duplicated from an earlier publication by different authors (Tang et al., 2020 [https://doi.org/10.18632/aging.103833]); Figure 3B is duplicated from an earlier publication by different authors (Zhou et al., 2020 [https://doi.org/10.2147/CMAR.S276297]); and Figure 5E is duplicated from an earlier publication by different authors (Yang et al., 2019 [https://doi.org/10.1186/s11658-019-0192-7]). The retraction has been agreed to because of evidence that significant portions of multiple figures were duplicated, affecting the interpretation of the data and results presented. The authors agree with the retraction.
