Another retraction for Naoki Mori (make that 23?)

The retraction total for Naoki Mori continues to rise.

The October issue of Biochemical and Biophysical Research Communications has retracted a 2007 paper by Mori et al for the same issues — manipulated images — that  brought down the 20-odd other papers of his since the scandal broke in late December.

Here’s the notice for the pulled paper, titled “Downregulation of citrin, a mitochondrial AGC, is associated with apoptosis of hepatocytes:” Continue reading Another retraction for Naoki Mori (make that 23?)

You can do that? A massive correction in Nature, but no retraction

This past April, Amparo Acker-Palmer and colleagues published a study in Nature, “Ephrin Bs are essential components of the Reelin pathway to regulate neuronal migration.” Within a day of its publication, Nature readers were raising questions about many of its figures. They started like this:

Andy Gu said:

Looks like Fig 1a, the two middle figures are actually the same with little move from desired regions. I don’t trust their data now…..

After several such comments, Nature senior editor Noah Gray weighed in: Continue reading You can do that? A massive correction in Nature, but no retraction

More on Hattori case from co-author: Did grudge lead to scientist’s fall?

We have an update on the case of Yoshiyuki Hattori, the Japanese endocrinologist who has had a half-dozen papers retracted because of issues involving reused data. We’ve reported on some of those retractions, and report on three new ones here.

As a trainee, Hattori spent some time in England, where he met Steven Gross, a prominent pharmacology researcher at Cornell. Gross was impressed with the young physician-scientist, and invited him back to his New York City laboratory to do a postdoc.

Gross’ name appears on one of the retracted articles, “NO suppresses while peroxynitrite sustains NF-κB: a paradigm to rationalize cytoprotective and cytotoxic actions attributed to NO,” which appeared in 2004 in the journal Cardiovascular Research and has been cited 42 times, according to Thomson Scientific’s Web of Knowledge.

According to the notice: Continue reading More on Hattori case from co-author: Did grudge lead to scientist’s fall?

Nature Medicine paper by former Montreal Heart Institute researcher Zhiguo Wang unlikely to be retracted

We’ve been reporting on the case of Zhiguo Wang, the Montreal Heart Institute researcher who was dismissed earlier this month for scientific misconduct. In the announcement about Wang’s dismissal, the institute said it had requested the retraction of three papers other than the two that Wang had himself retracted earlier this summer, making a total of five.

We’ve been following up with journals that published Wang’s work, with the help of eagle-eyed Retraction Watch readers, and last week reported on the first of those three additional retractions, in the Journal of Cell Science. Late last week, we heard from Juan Carlos Lopez, the chief editor of Nature Medicine, which had published a paper by the group. Lopez had earlier said he was waiting for a Montreal Heart Institute report on their findings. He tells us it’s unlikely the Nature Medicine paper will be among those retracted: Continue reading Nature Medicine paper by former Montreal Heart Institute researcher Zhiguo Wang unlikely to be retracted

Group retracts Nature Immunology paper for figure irregularities after posting a correction to Science

We’re following the case of a group that recently retracted a Nature Immunology paper for figure irregularities, soon after being forced to correct images in a Science paper for similar reasons.

The Nature Immunology paper, “The helminth product ES-62 protects against septic shock via Toll-like receptor 4–dependent autophagosomal degradation of the adaptor MyD88,” has been cited just twice since it appeared online in February 2011, according to Thomson Scientific’s Web of Knowledge. The retraction notice, which appeared online on July 19: Continue reading Group retracts Nature Immunology paper for figure irregularities after posting a correction to Science

Third retraction from dismissed Montreal cardiology researcher Zhiguo Wang appears

Ten days ago, we reported on the dismissal of Zhiguo Wang, a Montreal Heart Institute researcher who had already retracted two papers because of image manipulation. At the time, an official said the institute had requested three more retractions, but when we asked which three papers, we were told:

As written in the press release, the MHI has requested the retraction of three additional scientific articles. We will not be able to confirm the name of the scientific articles and/or publications until confirmation of the retractions.

The first of those three has now appeared, in the Journal of Cell Science, for the 2007 paper, “The muscle-specific microRNAs miR-1 and miR-133 produce opposing effects on apoptosis by targeting HSP60, HSP70 and caspase-9 in cardiomyocytes.” According to the retraction notice — which is unfortunately behind a paywall (see update at end): Continue reading Third retraction from dismissed Montreal cardiology researcher Zhiguo Wang appears

Group under investigation retracts second paper, claims errant figure was just a placeholder

The authors of a 2010 Journal of Immunology paper have retracted it, saying that part of one of the figures was actually a placeholder from another experiment.

According to the retraction notice for “Stimulation of FcgRI on Primary Sensory Neurons Increases Insulin-Like Growth Factor-I Production, Thereby Reducing Reperfusion-Induced Renal Injury in Mice” by Naoaki Harada, Juan Zhao, Hiroki Kurihara, Naomi Nakagata, and Kenji Okajima: Continue reading Group under investigation retracts second paper, claims errant figure was just a placeholder

Montreal Heart Institute researcher dismissed following two retractions for image manipulation

A Montreal Heart Institute researcher who retracted two papers less than a month ago has been fired from his post.

Zhiguo Wang, who had been funded by the Canadian Institute of Health Research and the Canadian Diabetes Association, studied the genes linked to heart rhythm abnormalities, among other subjects. Wang also has an appointment at the University of Montreal.

As first reported in Retraction Watch, Wang withdrew two papers for the Journal of Biological Chemistry (JBC) in the journal’s August 12 issue. The story was quickly picked up by Postmedia and the CBC. At the time, Wang told us: Continue reading Montreal Heart Institute researcher dismissed following two retractions for image manipulation

Following investigation, FASEB Journal retracts paper after agreeing to run a correction

A contested retraction has punctuated the complicated saga of a 2003 paper in the FASEB Journal. (FASEB stands for the Federation of American Societies for Experimental Biology.)

A retraction notice for the paper, “Molecular analysis of Nogo expression in the hippocampus during development and following lesion and seizure,” appeared in mid-June: Continue reading Following investigation, FASEB Journal retracts paper after agreeing to run a correction

India’s Kalasalingam University swiftly fires professor, kicks out six students after data manipulation scandal

Kalasalingam University in India has fired a professor who last month blamed unethical students for data manipulation that forced the retraction of three papers amid questions about five more.

As Krishna Pillai of the K2P blog reports, Sangiliyandi Gurunathan, head of Kalasalingam’s biotechnology department, was asked to resign, and did so on Friday, August 5. Kalasalingam also revoked the registrations of six graduate students who were co-authors on the retracted papers. Here’s the university press release with the details.

In comments to Retraction Watch for our earlier post, Gurunathan laid the blame on unethical students and journals, although his story didn’t quite hold together: Continue reading India’s Kalasalingam University swiftly fires professor, kicks out six students after data manipulation scandal
