Retraction Note: Downregulation of nicotinamide N-methyltransferase inhibits migration and epithelial-mesenchymal transition of esophageal squamous cell carcinoma via Wnt/β-catenin pathway (Molecular and Cellular Biochemistry, (2019), 460, 1-2, (93-103), 10.1007/s11010-019-03573-0)

The Editors-in-Chief have retracted this article. After publications, concerns were raised regarding image overlap in Fig. 6. The first concern about two cases of image overlap in Fig. 6c was addressed by the authors via a Correction [1]. Subsequently, a further concern has been raised regarding potential overlap between the EC-9706 and EC-9706 images in Fig. 6a. The authors have provided the full raw data for Fig. 6a and c to address these issues; however, the raw data files appear to contain additional cases of image overlap. The Editors-in-Chief therefore no longer have confidence in the presented data. None of the authors have responded to any correspondence from the publisher about this retraction note. The publisher has not been able to obtain a current email address for Xingxing Zang.
