Journal retracts paper due to image mismatch; one co-author alleges fraud

Researchers have retracted a biology paper that included an image mismatch — despite the fact that, as they claim, another image in the same paper confirms the original findings.

The authors say they plan to resubmit the paper with the corrected figure panel.

The second to last author — Carlo Croce, chair of the department of cancer biology and genetics at The Ohio State University — told us he believes there’s more to the retraction than what the notice says. Specifically, he said that the paper includes an image from a previous paper by the same authors, which he called “fraud.”

Here’s the latest retraction notice, published in Cell Death and Differentiation:

Surgery chair who blamed image issues on software logs three more retractions

A researcher who claimed image problems in a retracted paper were the result of a software glitch, and not intentional, has lost three more papers — all for image manipulation.

In two notices, the Journal of Biological Chemistry specifies that duplicated images were used to represent different experimental conditions; one notice simply says the paper was affected by image manipulation.

All of the notices specify the papers are being retracted by the publisher, the American Society for Biochemistry and Molecular Biology — which this month published a set of recommendations for preparing a paper, including how to avoid excessive manipulation.

The papers were published between 2002 and 2010, and all share the same last author (Paul Kuo, currently chair of surgery at Loyola Medicine) and first author (Hongtao Guo, at Duke).

Here’s the first notice:

Prominent Harvard researcher issues second retraction, again citing duplication

The former president of the Joslin Diabetes Center has withdrawn a second article within a month of his first, and issued extensive corrections to another paper in the same journal, all due to figure errors.

In November, we reported that Carl Ronald Kahn — also affiliated with Harvard Medical School — had pulled a highly cited 2005 paper from The Journal of Clinical Investigation because of image duplication issues, which Kahn told us were introduced during figure assembly. This December, Kahn retracted a 2003 paper published in The Journal of Biological Chemistry (JBC)—again due to duplication issues that the authors believe “were inadvertently introduced during figure assembly.”

Here’s the retraction notice for “Bi-directional regulation of brown fat adipogenesis by the insulin receptor,” cited 46 times, according to Clarivate Analytics’ Web of Science, formerly part of Thomson Reuters:

“Boom, headshot!” Disputed video game paper retracted

After a years-long dispute over a 2012 paper which suggested there might be some effects of first-person shooter video games on players, the journal has retracted the paper.

The stated reason in the notice: Some outside researchers spotted irregularities in the data, and contacted the corresponding author’s institution, Ohio State University, in 2015. Since the original data were missing, Communication Research is retracting the paper, with the corresponding author’s okay.

But as our story last month about this years-long dispute reported, there is a bit more to it.  Continue reading “Boom, headshot!” Disputed video game paper retracted

Undisclosed conflicts of interest usually lead to corrections – but for some journals, that’s not enough

When authors are faced with filling out a journal’s conflict of interest form, deciding what qualifies as a relevant conflict can be tricky. When such omissions come to light, only rarely do they result in retractions – and certainly not author bans. But there are exceptions.

In October, the journal Chest retracted a 2015 review article exploring how mechanical ventilation can be used most effectively to manage acute respiratory distress syndrome (ARDS) after finding that the authors failed “to disclose all relevant conflicts of interest.” What’s more, the journal initially planned to ban the two authors with undisclosed conflicts from submitting papers to the journal for three years, but ultimately decided against it.

The Committee on Publication Ethics says that retractions may be warranted in cases of undisclosed conflicts of interest, but in our experience, most notices that cite that reason mention other problems with the paper, as well. Not this case – here, the only thing that seemed wrong with the paper was the authors’ failure to mention their ties to a ventilator company. The authors requested a correction – the usual fix, one accepted by the other journals they contacted – but to Chest, that wasn’t enough.

Here’s the retraction notice for “Mechanical Ventilation as a Therapeutic Tool to Reduce ARDS Incidence”: Continue reading Undisclosed conflicts of interest usually lead to corrections – but for some journals, that’s not enough

At last, cancer reproducibility project releases some results — and they’re mixed

Nearly five years ago, researchers suggested that the vast majority of preclinical cancer research wouldn’t hold up to follow-up experiments, delaying much needed treatments for patients. In a series of articles publishing tomorrow morning, eLife has released the results of the first five attempts to replicate experiments in cancer biology — and the results are decidedly mixed.

As our co-founders Adam Marcus and Ivan Oransky write in STAT, the overall take-home message was that two studies generated findings similar to the original, one did not replicate the original, and two others were inconclusive.

They quote Brian Nosek, a psychologist at the University of Virginia, in Charlottesville, who runs the Center for Open Science, who has been leading the replication effort in his own field:

Breast cancer studies by fired Pfizer employee retracted

Last year, Pfizer fired one of its scientists following an investigation that ended with requests for retraction of five of her studies. Now, two of the five papers, which were first flagged on PubPeer, have been retracted.

One notice cites the Pfizer investigation, which found that cancer researcher Min-Jean Yin had included duplicated images in all five papers. Yin is the last author on both retracted papers.

Here’s the first notice from Clinical Cancer Research, which says most or all of the questioned images appear to be duplicates, and Pfizer — who sponsored the study and requested the retraction — can’t find the originals:

“Crucial experiments” missing from retracted plant study

A 2016 study was retracted from a Frontiers journal after editors realized the authors had omitted experiments that didn’t support the hypothesis. 

Gearóid Ó Faoleán, ethics and integrity manager at Frontiers, which publishes Frontiers in Plant Science, told us:

In accordance with our complaints protocol, the Field Chief Editor led the investigation that resulted in the decision to retract the paper.

Here’s the retraction notice: Continue reading “Crucial experiments” missing from retracted plant study

Authors retract two statin papers, one with problems “too extensive to revise”

Researchers in China have retracted two 2016 papers about the possible use of a cholesterol-lowering agent to treat bleeding on the brain.

One of the retracted papers in the Journal of Neurosurgery (JNS) had multiple problems that were “too extensive to revise,” according to the lengthy retraction notice, relating to issues with authorship, data analyses, and patient enrollment. The notice is signed by first author Hua Liu of the Nanjing Medical University in China.

Liu is also the first author of another recently retracted paper in Frontiers in Neuroscience, pulled for incorrectly categorizing patients.

The JNS retraction notice begins: Continue reading Authors retract two statin papers, one with problems “too extensive to revise”

Journal retracts gastric cancer study with multiple duplications, authors MIA

An oncology journal has decided to retract a 2012 paper on gastric cancer after discovering duplicated data in multiple figures.

According to the retraction notice, the journal’s editorial board received a tip from a reader regarding the potential figure issues. Oncology Reports launched an investigation, which confirmed the allegations. The authors failed to respond to the journal’s multiple requests for more information.

Here’s the retraction notice: Continue reading Journal retracts gastric cancer study with multiple duplications, authors MIA
