RETRACTED: KDM4A promotes the growth of non-small cell lung cancer by mediating the expression of Myc via DLX5 through the Wnt/β-catenin signaling pathway

Abstract

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the authors as they “found major problems in the data and conclusions through their later research”. 1. When the authors performed flow cytometry to detect apoptosis, the Annexin-V-coupled fluorophore they used was Fluor 647 (as described in the Methods section), which was incorrectly labelled as the Annexin-V-coupled fluorophore as FITC in their Figures (Fig. 5E, 7C and Fig. S1D). The excitation wavelengths of Alexa Fluor 647 (594/633 nm) are different from that of FITC (490 nm/520 nm), this mistake would lead to unreliability of their data. 2. The authors discovered a major error during the traceability of the antibodies used in the experiments. The primary antibody they used to detect KDM4A was actually a primary antibody for KDM6B, as evidenced by the western blots. KDM6B is a 177-kDa protein (consistent with the kDa shown in Fig. 1K and Fig. 2B), while KDM4A is a 150-kDa protein. 3. Lastly, the authors carelessly mislabeled KDM4A as KDM4B in Fig. 7. The authors and the Editors believe that the conclusions of the paper are not dependable, so we have decided to retract the paper. Apologies are offered to readers of the journal that this was not detected during the submission process.
