Rejected paper pops up elsewhere after one journal suspected manipulation

Figure 1F

In the autumn of 2022, a researcher in Turkey was reviewing a paper for a cardiology journal when an image of a Western blot caught her eye: A hardly visible pair of “unusual” lighter pixels seemed out of place. Magnification only bolstered her suspicion that something was off.

“This image made me think that the bands were cut one by one and pasted on a membrane background,” Şenay Akin, of Hacettepe University in Ankara, wrote in her comments to the editor of Cardiovascular Drugs and Therapy, a Springer Nature journal. “If this is the case, it indicates a manipulation [of] the results of this study.”

The editor, Yochai Birnbaum of Baylor College of Medicine in Houston, Texas, made a note to check the figure, adding below Akin’s comments in the editorial-management system: “I agree with the reviewer. It could be that the I/R band was manipulated.”

Misspelled cell lines take on new lives — and why that’s bad for the scientific literature

Image by Reese Richardson

Human cell lines represent key reagents for many research laboratories. Cell lines are often the first models that researchers choose for experiments such as gene manipulation and drug testing, as they are relatively accessible and inexpensive, particularly compared with mouse and other animal models.

However, cell lines also are prone to contamination by other faster growing cell lines. As a result,  many human cell lines purported to represent particular tumor types have been found by genetic testing to be contaminated by other cancer cells. This potential for confusion poses a serious problem for researchers who want to study a particular cancer type but end up using cells from an unrelated disease.

Our team studies wrongly identified nucleotide sequence reagents in cancer research, such as PCR primers and gene knockdown reagents. Recently in the context of an undergraduate student project, we decided to also check the identities of cell lines in a small group of papers on the human gene miR-145, which codes for a microRNA. We found wrongly identified nucleotide sequences and cell lines in numerous articles about miR-145, but also what appeared to be five misspelled identifiers of contaminated cell lines.

Cancer paper earns expression of concern nearly two years after investigation report is revealed

Carlo Croce

A Springer Nature journal has issued an expression of concern for a 16-year-old paper by Carlo Croce, the cancer researcher – and noted art collector – at The Ohio State University three years after the publication had received a correction for problematic images and roughly 20 months after the news division at Nature reported on a pair of institutional investigations into problems with Croce’s work. 

As we and others have reported, those investigations concluded Croce had not committed misconduct but had overlooked the misdeeds of others in his lab. 

Here’s the notice for the paper, “MicroRNA signatures of TRAIL resistance in human non-small cell lung cancer,” which Oncogene published in 2008:

KPMG government report on research integrity makes up reference involving Retraction Watch founders

An August 2023 report on research integrity by consulting firm KPMG, commissioned by an Australian government agency, contains a made-up reference, Retraction Watch has discovered.

Reference 139 of the report, “International Research Integrity Policy Scan Final Report: Compilation of information about research integrity arrangements outside Australia,” reads:

Gunsalus CK, Marcus AR, Oransky I, Stern JM. Institutional and individual factors that promote research integrity. In: Macrina FL, editor. Scientific Integrity: Text and Cases in Responsible Conduct of Research. 4th ed. Washington, DC: ASM Press; 2018. p. 53-82. 

A book with that title exists, but the four authors listed did not contribute a chapter, and the 2018 edition does not appear to contain a chapter with that title. We – Adam Marcus and Ivan Oransky – have indeed published with CK Gunsalus, but nothing resembling this reference.

Exclusive: Embattled dean accused of plagiarism in NSF report

Erick Jones

Erick Jones, the dean of engineering at the University of Nevada in Reno, appears to have engaged in extensive plagiarism in the final report he submitted to the National Science Foundation for a grant, Retraction Watch has learned.

The $28,238 grant partially supported a three-day workshop that Jones and his wife, Felicia Jefferson, held for 21 students in Washington, DC, in April 2022 titled “Broadening Participation in Engineering through Improved Financial Literacy.” Jefferson received a separate award for $21,757.

Jones submitted his final report to the agency in May 2023. Retraction Watch obtained a copy of that report through a public records request to Jones’s previous employer, the University of Texas at Arlington, and identified three published sources of extended passages he used without citation or quotation marks.

A cardiac surgeon’s tortuous efforts – including three lawsuits – to get the scientific record corrected

Vittorio Mantovani

For the past 14 years, a cardiac surgeon in Italy has been trying to blow the whistle on a study written by his former colleagues that has been the subject of several investigations – with two of them finding problems with the data. And despite defeating three defamation lawsuits, two  which were brought by authors of the paper, he’s not giving up yet. 

The 2006 paper, ‘Relationship between atrial histopathology and atrial fibrillation after coronary bypass surgery’, written by several of cardiac surgeon Vittorio Mantovani’s colleagues at the Ospedale di Circolo in Varese, was published in the Journal of Thoracic and Cardiovascular Surgery. To date, the paper – which has been cited 57 times, according to Clarivate’s Web of Science – has been investigated by at least two institutions as well as the journal. None have resulted in a retraction, despite one university finding that only a little more than half of the patients in the dataset could be matched unambiguously with biopsy samples. One university is also waiting on the journal to act before it considers reopening its own investigation. 

For Mantovani, the red flags started appearing in 2010, when he came across a minor discrepancy between two other papers written by him and his colleagues. He thought it was odd that in one dataset, patients were identified by name, but in the other, they were identified using numbers.

Medical society takes millions from company that sued it for defamation – and lost

When the American Society of Anesthesiologists last October announced the receipt of a $2.5 million donation from a drug company – “to advance education and innovation for our members”  – the news could have been dismissed with a shrug. After all, such gifts from industry to medical societies are commonplace. 

What makes this case noteworthy is that until the donation, the ASA and the drug maker, Pacira BioSciences, were better known as adversaries embroiled in a bitter lawsuit over three articles about the company’s flagship product the society had published in 2021 in its main scientific journal. 

The papers, which questioned the effectiveness of Exparel, an anesthetic intended for the treatment of patients undergoing orthopedic surgery and other procedures. As we reported in May 2021, as part of a larger suit against the ASA, Pacira demanded in legal filings that the ASA and its journal, Anesthesiology, retract the papers, which it considered libelous. 

The company didn’t hold that stance long, however. We wrote then:

Science ‘Majorana’ particle paper earns another editor’s note as expert committee finds no misconduct

Charles Marcus

A paper that led to hopes that Microsoft might one day build a quantum computer has “shortcomings” that do not rise to the level of misconduct, according to an expert panel convened by the University of Copenhagen.

The paper, originally published in March 2020 in Science, earned an expression of concern in 2021 following critiques of the work from two researchers, Sergey Frolov and Vincent Mourik. This week, Science editor in chief Holden Thorp replaced the expression of concern with an editor’s note referring to a new report from a panel of experts at the University of Copenhagen, saying  “we are alerting readers to this report while we await a formal decision on the matter from the Danish Committee on Research Misconduct.”

The panel’s report, dated Feb. 15, 2024, describes several of what it calls “shortcomings” but says “the excluded data did not undermine the paper’s main conclusions.” They also conclude the authors did not engage in “gross negligence” or scientific misconduct.

The last author of the Science paper, Charles Marcus, of the University of Washington, in Seattle, and the University of Copenhagen’s Niels Bohr Institute, told Retraction Watch he and his colleagues followed the recommendations by posting:

Highly cited scientist published dozens of papers after his death

Jiří Jaromír Klemeš

One of the most highly cited authors in engineering has continued publishing after his death more than a year ago. 

Jiří Jaromír Klemeš, a researcher at the Brno University of Technology in the Czech Republic and a top editor at an Elsevier journal that has come under fire for author self-citation, is listed as a coauthor of at least 49 papers published since his death in January 2023

Most of the articles do not mention that Klemeš is deceased. Whether they should have is not entirely clear. Publishers and journals aren’t consistent about the protocol following the death of a research collaborator –  a lack of consistency that has even stirred up some debate among our own readers in the past. 

Of the 49 papers we found posthumously listing Klemeš as a coauthor, 27 fail to mention his death. Commenters on PubPeer have spotted several of these instances and queried them without a meaningful response from the surviving authors.

Stanford prof who sued critics loses appeal against $500,000 in legal fees

Mark Jacobson

Mark Jacobson, a Stanford professor who sued a journal and a critic for $10 million before dropping the case, has lost an appeal he filed in 2022 to avoid paying defendants more than $500,000 in legal fees.

As we have previously reported, Jacobson:

…who studies renewable energy at Stanford, sued in September 2017 in the Superior Court of the District of Columbia for defamation over a 2017 paper in the Proceedings of the National Academy of Sciences (PNAS) that critiqued a 2015 article he had written in the same journal. He sued PNAS and the first author of the paper, Christopher Clack, an executive at a firm that analyzes renewable energy.
