Shikeagi Kato, an endocrinologist formerly of the University of Tokyo who resigned on March 31 amidst an investigation into his work, has retracted another paper, this one in Nature.
Here’s the notice for “DNA demethylation for hormone-induced transcriptional derepression,” which was the subject of a correction last October: Continue reading Shikeagi Kato, who resigned post in March, retracts Nature paper
Last month, we brought you the story of Soo-Kyung Kang, a Seoul National University stem cell researcher who has now retracted four papers amidst questions about image manipulation in a total of 14 studies. That story has drawn a great deal of attention in Korea, with comparisons to the Woo-Suk Hwang scandal, and has even led to a profile of Retraction Watch in the Seoul Daily, one of Korea’s largest newspapers.
We’ve now learned that the investigation has grown to 25 papers after an anonymous whistleblower warned about possible data fabrications in another paper by Kang, an associate professor of veterinary biotechnology, and Kyung-Sun Kang, director of the Adult Stem Cell Research Center in the same department (but no relation). And Soo-Kyung Kang was investigated in 2010, according to the Korea Herald.
The researchers’ labs are also under lockdown Continue reading Korean stem cell investigation expands to another researcher, and more papers
We have an update on the case of a University of Utah lab that retracted two Cell Metabolism papers last month after a fired lab technician disposed of two lab notebooks without permission. The team has now corrected two other papers, one in Blood and the other in the Journal of Clinical Investigation.
Here’s the notice from Blood: Continue reading Two new corrections for Utah group that retracted two Cell Metabolism papers for missing notebooks
Dipak Das, the UConn researcher whom the university earlier ths year found to have fabricated or falsified data more than 100 times, has four more retractions to his name.
The notices appear in the June 1, 2012 issue of the American Journal of Physiology: Heart and Circulatory Physiology, and suggest that Das was not all that cooperative: Continue reading Retraction count for resveratrol researcher Dipak Das rises to 12
For some journals, thorough retraction notices are the rule — and, when misconduct is involved, the price authors pay for abusing the trust of the editors and the readers. Others seem to take a more casual approach. Guess which we think is best.
Consider the case of a group of researchers in China led by Tan Jinquan, an immune system expert at Wuhan University. Over the past two years or so, Jinquan and colleagues have lost no fewer than a half-dozen papers containing evidence of image manipulation. But, depending on the journal pulling the articles, you might not know it.
A group of researchers at the University of Utah has retracted two papers from Cell Metabolism after they realized that a dismissed employee had tossed out data that were the basis of some error-laden figures.
Here’s the notice for both papers: Continue reading Authors retract two Cell Metabolism papers after “data were inappropriately removed from the laboratory”
Gerold Schuler, a German immunology researcher who shared the 2006 Deutscher Krebspreis — aka the German Cancer Prize — for his work that contributed to cancer vaccines has retracted a paper in International Immunology following concerns raised by a German science watchdog blog.
Here’s the notice: Continue reading Leading cancer vaccines researcher retracts paper for figure “discrepancies” flagged by watchdog blog
In a case that is a good reminder of why journal editors shouldn’t ignore anonymous tips, a Seoul National University stem cell researcher has been forced to retract four papers, and withdraw another under peer review, in Antioxidants & Redox Signaling following a whistleblower’s exhaustive analysis.
Two retractions by Soo Kyung Kang, a professor of veterinary biotechnology at Seoul National University, appeared on May 9 after an anonymous whistleblower sent a 70-slide PowerPoint presentation to the editors of ten journals that contained evidence of suspicious floating error bars, errors larger than actual measurements, pasted-together lanes in PCR gels and RNA and CHIP blots and several cases where the same control blot data is shown across different experiments and in different papers. In all, the whistleblower raises questions about 14 papers in the ten journals.
Here is the May 9 notice for “Nuclear Ago2/HSP60 contributes to broad spectrum of hATSCs function via Oct4 regulation”: Continue reading Whistleblower forces retractions of four stem cell papers amid questions about more than a dozen studies
ShouWei Han, who has been forced to retract six papers from various physiology journals following an investigation into his work by his former employer, the University of Louisville, has added another one to his tally.
Here’s the notice, from the American Journal of Physiology: Lung Cellular and Molecular Physiology: Continue reading Retraction seven for Shouwei Han, this one in the American Journal of Physiology
A group of researchers whose work has been under investigation at the University of Louisville has issued a correction for a paper in the American Journal of Respiratory Cell and Molecular Biology (AJRCMB).
The correction follows three retractions each in the Journal of Biological Chemistry and the AJRCMB, the latter of which made it clear that lab member ShouWei Han was responsible for the manipulations and duplications that brought down the papers. Here’s the new notice, which appeared in the March 1, 2012 issue of the journal: Continue reading Group investigated by University of Louisville corrects lung cancer paper after retracting six others
