Duplicated data, “careless errors” expire lung cancer paper

with one comment


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at Shenzhen Second People’s Hospital in China — shared “significant similarities” with another one of Sun’s papers that was retracted years ago.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”

with 4 comments

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

without comments

EnergiesAn electrical engineering paper published in April has been retracted because of similarities to a 2012 paper from different authors, including “almost identical” data in two of the papers’ tables.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

without comments

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.

Image issues force retraction of liver transplant papers

without comments

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: Read the rest of this entry »

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

with 10 comments

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:

There’s “no evidence” research was conducted at all in retracted cancer paper

with 2 comments

cov200h (1)To one reader of a paper on a nerve cancer, the researchers, based at a hospital in China, seemed to have found a very large number of cases of a rare cancer to study. That observation triggered an investigation into the paper that led to its retraction — and the concern that the authors in the paper never did the research at all.

The authors say they recruited 156 patients who had a particular kind of cancer that affects the tissue around nerves, known as malignant peripheral nerve sheath tumors. For context on how rare that is: Other researchers found a mere 1,182 new cases over a nearly four-decade period in the U.S. The study, according to the methods section of the paper, was supposedly done with patients who had a specific type of the disease, and who were

consecutively recruited from Wuhan Union Hospital, Huazhong University of Science and Technology in Wuhan (Hubei, China) between July 2000 and November 2012

According to the retraction note for “Common genetic variants in the microRNA biogenesis pathway are associated with malignant peripheral nerve sheath tumor risk in a Chinese population,” the hospital where the work was done never treated all of those patients:

Investigation ups nursing researcher’s retraction count to 3

with 2 comments

Journal of Clinical NursingThe Journal of Clinical Nursing is retracting a paper “due to major overlap with a previously published article” from the same journal, following an investigation by the National University of Singapore.

By our count, this is the third retraction for first author, Moon-fai Chan, all for “overlap” with other papers.

As we reported in May, the Journal of Advanced Nursing retracted a paper co-authored by Chan for “major overlap” with a paper in JCN, that too the result of the investigation. We’ve also learned that the journal Nursing & Health Sciences issued a similar notice last year for another pair of overlapped papers.

Chan said in a statement to Retraction Watch Read the rest of this entry »

Marine mammal injury study retracted for using restricted gov’t data

with one comment

Integrative ZoologyA 2012 paper that analyzed injuries to aquatic mammals in China has been retracted “due to the usage of restricted data from the Ministry of Agriculture of China.”

The authors — from Shandong University in China, The University of Hong Kong and the Peruvian Centre for Cetacean Research — “organized the collection of official documents related to strandings, bycatches and injuries of aquatic mammals in the waters of mainland China from provincial fishery administrations for the years 2000 to 2006,” according to the abstract. However, they may not have been supposed to do that.

Here’s the retraction notice from Integrative Zoology (which is paywalled, tsk, tsk):
