Mega-correction to several images in gastric cancer study

20.cover

A journal has issued a rather large correction — what we call “mega-correction” — to a 2014 paper on a gastric cancer biomarker that fixes problems with several of the study’s figures.

The authors write that despite the corrections, “the results and conclusions put forth in the article remain unchanged.”

The paper, “TMEFF2 Deregulation Contributes to Gastric Carcinogenesis and Indicates Poor Survival Outcome” explored the role of TMEFF2 in gastric cancer. The researchers found that the protein acts as a tumor suppressor, and low levels can indicate the presence of cancerous cells.

Here’s the full correction notice, published by Clinical Cancer Research in August:

“Dual submission issues” retract both copies of ovarian cancer paper

Journal of Cellular PhysiologyAuthors of a study on a potential biomarker for ovarian cancer have been hit with two retractions after the results were published twice.

We don’t usually see both copies of a duplicated paper retracted, but this is a somewhat unusual case. In November 2011, a group of authors submitted the paper to Gynecologic OncologyBut two months’ prior, the first author had decided to also submit the paper to the Journal of Cellular Physiology, without listing three of the other researchers, including the primary author on the paper. It was published by the Journal of Cellular Physiology first, then by Gynecologic Oncology, both in July, 2012. 

Jie Chen, first author on both articles, “takes full responsibility for the dual submission” and “other co-authors should be exempted from all responsibilities,” as the retraction notice from Gynecologic Oncology explains.

Authors retract two neuroscience papers for duplication and plagiarism

Journal of NeurosurgeryA tipster’s complaints have led to the retraction of two papers in the Journal of Neurosurgery for “plagiarism, duplicate publication, and copyright infringement.”

The corresponding author for both papers, Hung-Chuan Pan of Taichung Veterans General Hospital, had contacted the journal about publishing an erratum for one of the articles when the journal was tipped off by an email pointing out deeper problems in the two retracted papers.

The tipster provided evidence that alleged “a violation of ethics on the part of the authors,” according to the communications manager at the JNS Publishing Group, Jo Ann Eliason.

Both retraction notices, published October 2, detailed a number of “similarities” and “overlaps” in the papers.

Duplicated data, “careless errors” expire lung cancer paper

10.cover

A paper about the molecular details of lung cancer is being retracted for repeating datasets and “careless errors” in a pair of figures.

According to the note, the editor of Carcinogenesis wouldn’t have known about the problems if he hadn’t been tipped off that the paper by first author, XiaoJuan Sun — a researcher at Shenzhen Second People’s Hospital in China — shared “significant similarities” with another one of Sun’s papers that was retracted years ago. After the journal investigated the paper, it discovered that the authors had reported the same data as in the retracted paper “without significant additions or amendments,” along with some errors and inconsistencies.

Here’s the detailed note for “The EDA-containing cellular fibronectin induces epithelial mesenchymal transition in lung cancer cells through integrin α9β1-mediated activation of PI3-K /Akt and Erk1/2:”

P53 researcher submitted paper “without permission from his co-authors”

Screen Shot 2015-10-20 at 1.23.37 PM

One issue that we see pretty regularly is a paper submitted by one author without the permission of the others.

That’s what’s happened with “p53-induced Rap2B positively regulates migration in cells exposed to glucose deprivation,” published in July by Molecular Carcinogenesis. The paper looks at a protein called p53, well-known to regulate cell growth and, when mutated, cause cancer.

Here’s the pretty straightforward retraction note:

Retraction strikes power grid paper with “almost identical” content to previous study

EnergiesAn electrical engineering paper published in April has been retracted because of similarities to a 2012 paper from different authors, including “almost identical” data in two of the papers’ tables.

The authors were unable to provide the original numbers for the suspect tables, along with a pair of “similar” figures, which bore a striking resemblance to ones presented in the same 2012 paper. Corresponding author Tao Jin at Fuzhou University in China requested the withdrawal “in order to repeat the experiments and obtain new data.”

Energies posted the retraction October 1.

Here’s it is, in full:

Failure to reproduce key experiments retracts cancer study

Medical OncologyA group of Chinese cancer researchers has retracted a paper in Medical Oncology after they discovered that “several key experiments” were not reproducible.

The paper, “Decreased Warburg effect induced by ATP citrate lyase suppression inhibits tumor growth in pancreatic cancer,” was published in March. It found that suppressing the enzyme ATP citrate lyase could be used to treat pancreatic cancer.

However, the authors decided to pull the paper when some of the findings couldn’t be reproduced. 

Here’s the notice:

Elsevier retracting nine papers for fake peer review

elsevierThe fake peer review retraction count continues to mount.

Elsevier is retracting nine papers from five journals because fake email addresses for reviewers were provided during submission of the original manuscripts. According to a statement from the publisher: Continue reading Elsevier retracting nine papers for fake peer review

Image issues force retraction of liver transplant papers

ajtranspA group of researchers in Hong Kong and China have lost a pair of papers on liver transplantation after concerns were raised about the “origin of images” in the two studies.

The articles appeared in the American Journal of Transplantation in January and February of 2006, and came from the lab of S. T. Fan, of the University of Hong Kong. When the authors were asked about the images, they “were unable to satisfactorily mitigate the concerns.”

According to this bio from the journal Hepatobiliary Surgery and Nutrition, Fan: Continue reading Image issues force retraction of liver transplant papers

Mystery: PLOS One seeks investigation after publishing two papers with “substantial overlap”

Screen Shot 2015-10-01 at 4.27.21 PMPLOS One has retracted one of two cancer papers with “substantial overlap” that were reviewed simultaneously by different editors.

This one’s a bit of a mystery — neither of the papers share an author, and no authors share institutions. Once the editors discovered the overlap, they contacted the authors. One group of authors provided the requested documentation for the experiments. The other did not — so the editors retracted that article, even though it was published months before the other one.

In the meantime, the editors have asked the authors’ institutions investigate how the articles — which contain entire identical sentences, and some extremely similar figures — were put together. According to a statement from the editors:
