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.
Zhao Kai, the study’s first author from the Qilu Hospital of Shandong University and Zibo Central Hospital (both in China), took full responsibility for the error.
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.

The paper was published in March, 2015 — the same month publisher BioMed Central (BMC) pulled 43 papers for fake reviews.
According to the retraction notice in the European Journal of Medical Research, the authors’ institution in China informed the publisher that the authors had used a third party to help with copyediting and submission to the journal, raising concerns about the authorship of the paper.
In a massive cleanup, Springer and BioMed Central announced today they are retracting 58 papers for several reasons, including manipulation of the peer-review process and inappropriately allocating authorship.
The papers appeared in seven journals, and more are under investigation.

Sarah Darby, last author of the now-retracted paper from the University of Oxford, UK, told Retraction Watch that the mistake was made by a doctoral student. When the error was realized, Darby said, she contacted the Journal of Clinical Oncology (JCO), explained the issue, and asked whether they would prefer a retraction or a correction. JCO wanted a retraction, and she complied.
The journal allowed the authors to publish a correspondence article outlining their new results.
According to the retraction notice, the journal — Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy — accepted the paper due to positive feedback from someone assuming the identity of an expert reviewer, using an email address provided by the author of the study.
An official from the author’s institution in Turkey informed us that it will conduct an investigation.
Here’s the retraction notice for “Diagnosis of cervical cancer cell taken from scanning electron and atomic force microscope images of the same patients using discrete wavelet entropy energy and Jensen Shannon, Hellinger, Triangle Measure classifier:” Read the rest of this entry »
Nearly 50 years ago, researchers in Uppsala, Sweden used cells from a patient to establish a brain tumor cell line that has become widely used. But a new study suggests that the most common source of that cell line used by scientists today may not be derived from that original patient’s tumor, raising questions about the results obtained in hundreds of studies.
In a new paper out today in Science Translational Medicine, Bengt Westermark, of Uppsala University, and colleagues describe what they found when they performed a forensic DNA analysis comparing the widely used version of the cell line to the original. The findings are consistent with those of other analyses in which cell lines turn out not to be what researchers thought, a problem we’ve focused some attention on.
Here’s an email interview with Westermark about the findings and their implications: Read the rest of this entry »
A cancer researcher has earned seven more retractions following an investigation into his work by his former employer, MD Anderson Cancer Center in Texas, bringing his total to 18 retractions.
All of the new retraction notices, issued by The Journal of Biological Chemistry (JBC), stem from image-related issues. The now-retired Aggarwal has seven papers that have each been cited at least 1,000 times, and in 2015, he was on Thomson Reuters Web of Science’s list of The World’s Most Influential Scientific Minds. With these new notices, he also has made it to our leaderboard of individual researchers who’ve racked up the most retractions.
