Retraction Watch is a great website. As the name implies, it focuses on a key aspect of quality control in science, the retraction of scientific papers that have already passed peer-review and were published when serious concerns about those papers come to light.
Retracting published papers is similar to phase IV clinical trials – tracking side effects of drugs that have already been approved and are on the market so regulatory agencies can monitor for post-marketing concerns and recall the drug if necessary.
From late September 2015, we received several expressions of concern from third parties that the electrophoresis gels presented might have been subject to unwarranted digital manipulations (added and hidden bands or zones, including in the control samples and the DNA ladder). A detailed independent investigation was carried out by animal in accordance with the Committee on Publication Ethics (COPE) guidelines. This investigation included an analysis of the claims using the figures as submitted, and reassessment of the article by one of the original peer-reviewers in light of the results of the analysis. The authors were notified of our concerns and asked to account for the observed irregularities. In the absence of a satisfactory explanation, the institution was asked to investigate further. The University of Naples concluded that multiple heterogeneities were likely attributable to digital manipulation, raising serious doubts on the reliability of the findings.
Based on the results of all investigations, we have decided to retract the article.
