Retraction: Retracted:Resveratrol inhibits oesophageal adenocarcinoma cell proliferation via AMP-activated protein kinase signaling
Asian Pacific Journal of Cancer Prevention (APJCP) has retracted the article titled “Resveratrol Inhibits Oesophageal Adenocarcinoma Cell Proliferation via AMP-activated Protein Kinase Signaling”(1) for reason of having duplicated contents brought to the attention of APJCP’s editorial office by the following email content:
“Dear Editors of Gastroenterology and Hepatology, Acta Pharmacologica Sinica, Asian Pac J Cancer Prev, Clinical and Experimental Hypertension,
I write to you from the editorial office of PLOS ONE to inform you of concerns related to duplicated content in articles published by your journals. We have been following up on concerns of overlapping text and duplicate Western blots within the following PLOS ONE article:
 Berberine Improves Kidney Function in Diabetic Mice via AMPK Activation
Received: June 9, 2014; Accepted: October 23, 2014; Published: November 19, 2014
It was initially brought to our attention that there is duplication of Western blot images between the PLOS ONE article and the following published papers:
 Brain Injury (Received 28 Oct 2013, Accepted 4 Jan 2015, Published online 20 Mar 2015) doi: 10.3109/02699052.2015.1004746: Figure 6b GAPDH is similar to Figure 2A AMPK in 
 Exp Mol Pathol (Received 24 Feb 2014, Accepted 10 Sep 2014, Available online 16 Sep 2014) doi:10.1016/j.yexmp.2014.09.006: Figure 5B GAPDH is similar to Figure 2A AMPK in ; Figure 5C Occludin is similar to Figure 2A LKB1 in 
 Korean J Physiol Pharmacol, (Received 7 Nov 2013, Accepted 3 Jan 2016) doi: 10.4196/kjpp.2016.20.4.325 RETRACTED: Figure 6B GAPDH is similar to Figure 2A AMPK 
Please note that the KJPP paper has been retracted as a result of the content duplication issues.
During the course of our follow up, we have discovered additional instances of possible duplication as follows:
 Gastroenterology and Hepatology (Accepted 6 Aug 2014, Accepted ms online 28 Aug 2014, Published 23 Feb 2015) doi:10.1111/jgh.12723: Figure 1d AMPK is similar to Figure 2A AMPK in , Figure 3a iNOS is similar to Figure 2A LKB1 in 
 Acta Pharmacologica Sinica (Received 4 Mar 2014, Accepted 28 July 2014, Published 17 Nov 2014) doi: 10.1038/aps.2014.88: Figure 1 A and B bar charts are similar to Figure 1 A and B bar charts in , Figure 1E AMPK is similar to Figure 2A AMPK in , Figure 1E p-AMPK is similar to Figure 2A P-AMPK in , Figure 1E bar chart is similar to the Figure 2A bar chart in 
 Asian Pac J Cancer Prev (Published Jan 2014) doi: 10.7314/APJCP.2014.15.2.677: Figure 3A GAPDH is similar to Figure 2A AMPK in  and p27 kip1 is similar to Figure 2A P-AMPK in 
 Clinical and Experimental Hypertension (Received 15 Sep 2015, Accepted 24 Nov 2015, Published 5 May 2016) doi: 10.3109/10641963.2015.1131288: Figure 2A LKB1 and P-AMPK are similar to Figure 2A LKB1 and P-AMPK in , Figure 2B P-AMPK and AMPK are similar to Figure 2B P-AMPK and AMPK in , Figure 2A and B bar charts appear similar in both articles. Figures 1A, B and C including Western blots and charts appear similar in both articles. Figure 6C AMPK is similar to Figure 2A AMPK in  (note that authors Min Hu and Bo Liu may be the same as authors on the retracted KJPP paper above)
Articles , , , and  contain various amounts of duplicated text in the Results sections when compared to the PLOS ONE article. Note that there may be other instances of duplicated data and/or text between the above articles aside from those affecting the PLOS ONE article.
For at least some of the duplicated text, it appears that some of the manuscripts were under consideration at overlapping times. We have been informed that an external biotechnology company conducted the Western blot experiments and provided the raw blots to the authors for the PLOS ONE paper. How the duplications in text and figures arose remains unresolved.
Although our correspondence with the authors about this matter is ongoing, we have determined that it is appropriate to issue a retraction of the PLOS ONE article, and the retraction notice will provide details of the similarities in content with the above-listed articles. We will also report this matter to the PLOS ONE authors’ institution.
I hope that the information provided above is helpful. If you have any questions in the course of any follow up on this matter, please do not hesitate to get in touch.
