Correction to ‘Nuclear ubiquitination by FBXL5 modulates Snail1 DNA binding and stability’

In December 2025, concerns were raised on PubPeer (https://pubpeer.com/publications/8125E2B29BC285753A3BF08B607988)about the potential duplication of the Sin3A bands in Figures 6A and6B, as well as a possible alteration of the background in the Snail1-HA panel of Figure 6B that could indicate a composite image.The authors have reviewed these issues and now wish to provide a corrected version of Figure 6.The authors confirmed that the Sin3A bands in Figures 6A and6B were duplicated during image assembly.They have provided all the blots corresponding to these two figures, including the one corresponding to Sin3A of Figure 6A.For Figure 6B the authors provided a different contemporaneous Sin3A blot confirming the results: Sin3a is present specifically in the NE fraction without differences between shCtl and shL5 conditions.A similar result (no change in Sin3a upon L5 downmodulation) is also shown in other figures of this article (Figures 3B andS2B).
