A university vice president has received his first retraction – and disagrees with it, according to the journal. 

The retraction for Jaydutt Vadgama, the Vice President for Research and Health Affairs at the Charles R. Drew University of Medicine and Science, comes after a commenter on PubPeer noted similarities between data in two papers from the same group. Similar comments have led to corrections to two other papers by Vadgama, who is also professor at the David Geffen School of Medicine at University of California, Los Angeles.

The retracted article, “A83-01 inhibits TGF-β-induced upregulation of Wnt3 and epithelial to mesenchymal transition in HER2-overexpressing breast cancer cells,” appeared in Breast Cancer Research and Treatment in 2017. It has been cited 38 times, according to Clarivate’s Web of Science. 

The retraction notice, published this month, states:

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.”

The director of one the nation’s premier cancer centers has been suspended amid concerns over several of his papers – but he tells Retraction Watch it is unrelated to comments about that work on PubPeer. 

An email Wednesday to employees at New York University’s medical center – and a subsequent message to staff at the institution’s Perlmutter Cancer Center – explained that Benjamin Neel, the former director of the center, had been suspended. 

The letter, signed by Steven Abramson, a rheumatologist and executive vice president at NYU Langone Health, did not state the reason for the move:

The chair of the Department of Pulmonary Immunology at the University of Texas at Tyler Health Science Center lost a paper last year after an institutional investigation found several issues with the data in the article.

Although the researcher, Ramakrishna Vankayalapati, is still identified as the chair on his online profile and the department’s website, he no longer holds that position, Retraction Watch has learned. 

The paper, “Ornithine-A urea cycle metabolite enhances autophagy and controls Mycobacterium tuberculosis infection,” was published in Nature Communications in July 2020. It has been cited 21 times, according to the journal’s statistics.

Another article co-authored by Australian journalist Maryanne Demasi will be marked with an expression of concern for image duplication, Retraction Watch has learned. 

Demasi’s reporting has cast doubt on statins and raised the possibility of a link between wi-fi and brain tumors – controversial claims she and co-authors have previously told us they believe made her scientific publications a target of critique. She has not responded to our request for comment on the forthcoming expression of concern. 

Following an investigation by the University of Adelaide into allegations of image manipulation in Demasi’s PhD thesis in rheumatology, one paper that resulted from the dissertation was retracted and another was marked with an expression of concern.

A former associate dean for research at the University of Wyoming who was named as one of Clarivate’s Highly Cited Researchers for 2021 was sanctioned by the university years ago, Retraction Watch has learned.

Jun Ren, who studies the heart and diabetes, left Wyoming sometime in 2019 or 2020, according to a press release noting his citation achievements, after serving at different times as director of the NIH-funded INBRE program as well as associate dean. But following an investigation of his work between 2013 and 2015 that Ren says found “reckless mistakes” and “no intention to obtain specific results,” he was removed as director of what he says was a multi-million dollar research program and lost “administrative, editorial, grant review and advisor positions.”

Ren now says that he

A UPenn professor now has six papers with a correction, expression of concern, or retraction in two PLOS journals after one published an extensive correction to a 2018 paper. 

The correction adds to two retractions and three expressions of concern for papers in PLOS Pathogens and PLOS ONE with Erle Robertson, a microbiology professor and vice chair of research for the department of otorhinolaryngology at the University of Pennsylvania, as a senior author. The actions on each paper happened after commenters on PubPeer pointed out issues. 

The correction to “STAT6 degradation and ubiquitylated TRIML2 are essential for activation of human oncogenic herpesvirus” states:

A kidney research group led by a medical school dean has accumulated five retractions. 

All five came within the last year, after commenters on PubPeer pointed out image similarities. 

Joseph I. Shapiro, vice president and dean of the Joan C. Edwards School of Medicine of Marshall University in Huntington, West Virginia, is an author on each of the five papers and corresponding author for two. (Shapiro recently said he will be stepping down at the end of this month after ten years as dean, but will remain a tenured professor, according to a news report.)

A urology researcher who stepped down from his post as department chair after an institutional investigation prompted by Retraction Watch reporting has lost another paper. 

The article apparently was not flagged during a misconduct investigation, but a PubPeer commenter noted overlapping images in August 2021. 

Hari Koul had been interim chair of the department of biochemistry and molecular biology at LSU Health New Orleans until last December. He stepped down from the post (but remains a professor) amid the university’s investigation of allegations that he secured grants from two federal agencies for the same research project, following reporting by Retraction Watch in October. 

An LSU Health New Orleans spokesperson told Retraction Watch the “process has not been completed.”

A group of biomedical engineering researchers has lost four papers because they appear to be recycling their images from other papers. 

The retractions for the group, from Banaras Hindu University in India, span papers published between 2011 and 2014. The retractions began in 2020, after anonymous PubPeer commenters pointed out the similarities between images. The four papers have been cited a total of 140 times, according to Clarivate Analytics’ Web of Science.

The latest paper to be retracted, “Alleviation of glutamate-mediated neuronal insult by piroxicam in rodent model of focal cerebral ischemia: a possible mechanism of GABA agonism,” was originally published in Springer Nature’s Journal of Physiology and Biochemistry in 2014. It has been cited 12 times. 

According to the retraction notice:
