On April 27, the Journal of Biological Chemistry (JBC) retracted nine papers by a researcher based in Israel, including some dating back to 2000.
The reason: Image manipulation.
Michal Neeman, vice president of The Weizmann Institute of Science, told us that the researcher, Rony Seger, is under investigation following an allegation of misconduct affecting papers in multiple journals.
So far, we’ve found 11 retractions for papers by Seger, a molecular biologist. In the notices, the authors state they have “full confidence” in the findings, and in many instances have replicated the work.
According to Neeman:

Researchers in China have retracted a 2016 paper exploring the replication behaviors of a retrovirus, after discovering that the key results could not be reproduced — possibly because their cell cultures had been contaminated.
The authors also cite a disagreement with a colleague, who they say contributed to the work but does not want to be listed as an author.
Here’s the retraction notice for “Nuclear import of prototype foamy virus transactivator Bel1 is mediated by KPNA1, KPNA6 and KPNA7,” published in the International Journal of Molecular Medicine: Continue reading Authors pull virus replication paper after they cannot replicate results
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.

After researchers in China included the same images in two papers published online one month apart, one paper has been retracted, and the other flagged with an expression of concern.
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.

A journal has retracted a paper after a reader pointed out some of the data looked familiar — and the authors never responded to the allegations.
According to the retraction notice in the International Journal of Molecular Medicine, the reader showed the journal that the histological data in two of the figures were from another published paper by different researchers. But when the journal contacted the authors on several occasions, they didn’t hear back.

Researchers have retracted their third paper due to missing original data, following an investigation at their former institution in New York.
We’ve previously reported on two retractions of papers co-authored by Bhagavathi Narayanan and Narayanan K. Narayanan, previously based at the New York University (NYU) School of Medicine. The studies were pulled when the pair couldn’t provide original images to investigators at NYU School of Medicine. One author has blamed the lack of original data on the abrupt closure of her previous institution in 2004, after it allegedly misspent millions in federal grants.
However, the latest retraction affects a paper published eight years later in the International Journal of Oncology. Its coauthors include Bhagavathi Narayanan, Narayanan K. Narayanan and Rajkishen Narayanan; we haven’t been able to uncover if there is a relation between them.
A spokesperson for the NYU School of Medicine sent us this statement: Continue reading Authors retract third cancer paper for missing original data
After questions from a reader, researchers took a second look at their data about the effects of a vitamin A metabolite on tumor cells, and realized their key finding was inaccurate.
They’re now retracting the paper, from Molecular Medicine Reports, because it originally reported that higher concentrations of retinoic acid (RA) were more effective in curbing the proliferation of brain tumor cells. But it seems that the RA dose made less of a difference than they originally believed, according to the retraction notice:

After finding several errors in their paper about the molecular activity underlying gastric cancer, the authors unanimously decided to retract it.
According to the retraction note, three figures in the paper had β‑actin bands that were omitted, interchanged, or both.
The retraction note provides the details:

A paper on a way to inhibit arthritis has been retracted following an investigation confirming that it plagiarizes a figure from another paper on the same topic.
The paper, “Blockade of 11β-hydroxysteroid dehydrogenase type 1 enzyme inhibits experimental collagenase-induced osteoarthritis,” was published in Molecular Medicine Reports. A figure claims to show cartilage treated with a specific inhibitor:
The retraction note tells us that the authors reproduced the figure from another paper in Inflammation — which describes a different inhibitor:

A group of Chinese researchers has retracted a paper, saying that an outside lab switched their immunofluorescent stains with another research group’s.
The group has decided to repeat the experiments on their own next time.
