According to Jeanine D’Armiento, the study’s last author, the newly retracted paper in Clinical Science contained a figure from a Journal of Hypertension paper published by the same authors earlier that year.
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:
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.
Here’s the first notice:
Last March, a PhD student at Harvard filed a misconduct allegation against his mentor, a prominent stem cell researcher. Three months later, he was taken from his home by police in the middle of the night for a forced psychiatric evaluation.

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.
In 2011, authors of a Nature letter caught some flak for issuing a lengthy correction to a neuroscience paper that had raised eyebrows within days of publication — including some suggestions it should be retracted.
The correction notice, published months after the original letter, cited errors in image choice and labeling, but asserted the conclusions remained valid.
Now, those conclusions appear up for debate. In a recent Nature Brief Communications Arising (BCA) article, a team that raised concerns about the paper five years ago says they are unable to reproduce the results. But the authors of the original paper aren’t convinced: They argue that the BCA fails to cite important evidence, has a “complete absence or low quality of analysis,” and the scientists disregard some of their data.
Four of the newly corrected papers have a common last and corresponding author: Luke O’Neill of Trinity College Dublin in the Republic of Ireland. O’Neill is also a co-author of the remaining paper that was fixed. O’Neill told us the mistakes were a “bit sloppy,” noting that he takes responsibility for the errors in the four papers on which he is last author.
O’Neill forwarded Retraction Watch a comment he received from Kaoru Sakabe — data integrity manager at the American Society for Biochemistry and Molecular Biology (which publishes The Journal of Biological Chemistry (JBC)) — that reads: Read the rest of this entry »
According to the retraction notice in the International Journal of Molecular Medicine (IJMM), the authors intended that the two different papers offered “different research perspectives.”
Meanwhile, the Chinese Medical Journal — which published the same images one month later — has issued an expression of concern (EOC), noting it “should not be considered as a statement regarding the validity of the work.” Both papers describe how cells regulate blood flow to the retina.
Normally, journals choose to retract the most recent paper containing duplicated images, but in this case, the IJMM paper was published online in February 2016, and the Chinese Medical Journal in March.
In November, a vice president at an institution in Taiwan retracted a hotly debated cancer paper from Nature Cell Biology, citing image problems including duplications. Now, the Journal of Biological Chemistry has done the same, again citing image duplications.
There are a few things to note about the latest retraction: One, the last author is again Kuo Min-liang — who holds an appointment at National Taiwan University (NTU), and is also a vice president at Kaohsiung Medical University in Taiwan. Kuo is currently facing allegations that he accepted bribes to add co-authors to his papers; NTU told us it is investigating the latest retraction in the Journal of Biological Chemistry, including Kuo.
The other notable feature of the retraction is the notice itself, which lists a remarkable number of duplicated images. Take a look:
The latest retraction for Tina Wenz in the Journal of Applied Physiology mentions the probe at the University of Cologne in Germany, which recommended retracting six of her papers. One had already been retracted by the time the report was released; last month, we reported that two others had been pulled. Now, we’ve come across a fourth.
