Researchers in China have retracted a 2016 paper in Oncology Letters on the anti-cancer properties of aspirin because, well, it was a disaster from top to bottom.
In the spirit of showing rather than telling, we’ll let the retraction notice do the work: Continue reading A real headache: Here’s one from the “What else could go wrong?” files
Researchers in China have retracted a pair of papers in the same journal after running into “irreconcilable” differences with the articles.
Both articles appeared in Molecular Medicine Reports, from Spandidos.
One article, “Combined treatment with extracorporeal shock‑wave therapy and bone marrow mesenchymal stem cell transplantation improves bone repair in a rabbit model of bone nonunion,” published in November 2017, suffered from, well, serious nonunion: Continue reading “Irreconcilable” differences about author order, other issues topple two articles in Spandidos journal

Here’s an object lesson for scientists who find out they’ve been ripped off by other researchers: Taking matters into your own hands can produce results.
An aggrieved author’s doggedness led to the retraction of a 2013 paper that plagiarized his work, along with the revocation of a doctoral degree by one of the scientists responsible for the theft and sanctions against another.
We don’t often get the blow-by-blow, but in this case we have the details to share. The story begins in early 2017, when Andrew Boyle, a professor of cardiac medicine at the University of Newcastle, in Australia, noticed something fishy in an article, “Cathepsin B inhibition attenuates cardiac dysfunction and remodeling following myocardial infarction by inhibiting the NLRP3 pathway.” The paper had appeared in a journal called Molecular Medicine Reports, from Spandidos.
The article, published by a group from Shandong Provincial Hospital, contained a pair of figures that Boyle recognized from his 2005 article in the Journal of Molecular and Cellular Cardiology. One of the images had been altered, but the other was a patent duplication.
Boyle explained that: Continue reading Persistence pays off for plagiarized author: emails spur retraction, sanctions against researcher
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.
Here’s the retraction notice: Continue reading Journal retracts gastric cancer study with multiple duplications, authors MIA
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.
Here’s the retraction notice: Continue reading Authors use same images in two studies — one is retracted, the other flagged by journal
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.
Here’s the retraction notice: Continue reading Journal pulls cancer paper that used others’ data; authors MIA
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:
