ORI finds misconduct in case of biologist paid $100K by university to leave

A biologist who studied the impact of diabetes on the eye inappropriately altered data in five images from three papers, according to a new finding of misconduct issued by the U.S. Office of Research Integrity (ORI).

Readers may be familiar with the subject of the findings: Azza El-Remessy, a former tenured associate professor at the University of Georgia (UGA) in Athens, spoke to us earlier this year about her battle with UGA. In June 2016, UGA found her guilty of research misconduct and recommended she be terminated. El-Remessy fought back, hiring a lawyer to contest the findings, and the university ultimately paid her $100,000 to leave. (For more, here’s UGA’s June 2016 investigation report and the settlement agreement between UGA and El-Remessy.)

“No wrongdoing had occurred,” says Karolinska, following investigation of cancer research

A journal has removed an expression of concern for a 2011 paper after Karolinska Institutet (KI) “concluded no wrongdoing had occurred.” 

In June, Journal of Cell Science (JCS) issued the expression of concern, after a reader contacted the editors with questions about the data in one of the figures. JCS investigated but could not resolve the issue, and in March 2017 turned the case over to KI where the authors are based.

The 2011 paper had already received a correction in 2016, citing inadvertent figure duplication.

In late August, KI concluded its investigation into the 2011 paper by last author Boris Zhivotovsky; JCS has now updated the expression of concern with a publisher’s note: Continue reading “No wrongdoing had occurred,” says Karolinska, following investigation of cancer research

Project to “fact check” genetic studies leads to three more retractions. And it’s just getting started.

Jennifer Byrne

A project to identify studies doomed by problematic reagents has triggered three more retractions, bringing the total to five.

Jennifer Byrne, a scientist at the University of Sydney, who developed the the idea of double-checking the nucleic acid sequences of research materials — thereby ensuring studies were testing the gene in question — told Retraction Watch that all three retractions came after she started emailing journals in January  to alert them to the problems: Continue reading Project to “fact check” genetic studies leads to three more retractions.

Two more retractions for former US prof who altered dozens of images

Two journals have retracted papers by a biologist who was recently found guilty of misconduct by his former employer, the University of Colorado Denver, bringing the total to five.

The investigation report by UC Denver, which we obtained earlier this year via a public records request, had recommended one of the two newest retractions, which appears in the journal Hepatology. The other retraction, in the Journal of Immunology, was not flagged by the report — which found, among other conclusions, that Almut Grenz had altered multiple values in research that had already been submitted for peer review.

Here’s the notice for the Journal of Immunology paper:

Authors withdraw study, citing “accidentally duplicated” images

Researchers in Australia have withdrawn a 2006 paper in The Journal of Biological Chemistry (JBC), citing image duplication.

In the withdrawal notice, published July 14, 2017, the authors claim that the “errors do not impact the underlying scientific findings of the article.”

Although the notice does not mention an investigation, a comment on PubPeer on March 2017—signed by Mark Hargreaves, the vice-chancellor at the University of Melbourne—indicates that the university conducted an investigation to assess the issues in the paper and determined that research misconduct “did not occur.”

Here’s the withdrawal notice for “Induction of the unfolded protein response in familial amyotrophic lateral sclerosis and association of protein-disulfide isomerase with superoxide dismutase 1:” Continue reading Authors withdraw study, citing “accidentally duplicated” images

UCSF, VA investigations find “clear evidence” of misconduct in cancer papers

Earlier this year, the University of California, San Francisco and the San Francisco Veterans Administration Medical Center teamed up to write a letter.

Addressed to the editorial office at the American Association of Cancer Research (AACR), the letter, parts of which have been published in a retraction notice, contained information concerning two papers on genetic risk factors for a type of kidney cancer and a type of uterine cancer, respectively, published in different AACR journals over a decade ago by researchers affiliated with the institutions.

The papers had been at the center of research misconduct investigations at both UCSF and the VA and the investigations came to the conclusion that both papers contained:

fabrication or falsification of data that constitutes Research Misconduct.

Though one of the papers has been retracted, it’s unclear what will happen to the other. [Note: See update at the bottom of the post.] Continue reading UCSF, VA investigations find “clear evidence” of misconduct in cancer papers

Lost citation snuffs out Aussie fire paper

A journal has retracted a 2016 paper on wildfires in Australia because the authors neglected to cite earlier work — an unintentional lapse, they said.

The article, “Projected changes in Australian fire regimes during the 21st century and consequences for Ecosystems,” appeared in the International Journal of Wildland Fire. The authors are Sandy Harrison and Douglas Kelley,  of the University of Reading, in the UK. Kelley appears to have done his share of the work as a PhD student at Macquarie University in Australia.

According to the notice: Continue reading Lost citation snuffs out Aussie fire paper

Journal corrects paper by researcher sanctioned for misconduct

A biology journal has issued a correction to a 2014 paper by a researcher with 11 retractions, citing “inadvertent errors” that don’t affect the conclusions.

The researcher, Rony Seger, was recently sanctioned by his institution (The Weizmann Institute in Israel) following a finding of “serious misconduct” involving data manipulation. Specifically, the institute barred him from supervising graduate students, even future ones; his lab is now dedicated to replicating his previous work, with the help of a technician.

Last month, Michal Neeman, vice president of The Weizmann Institute of Science, told us she wasn’t sure how many additional papers by Seger would need to be retracted or corrected.

Recently, one more was revealed — in the August issue of Molecular and Cellular Biology, the following correction notice appears:

Third retraction for former rising star found guilty of misconduct

A once-prominent researcher in the field of infectious disease — who was found guilty of misconduct last year— has had a third paper retracted, a 2006 article in PNAS.

Last year, the University of Dundee in Scotland found that Robert Ryan had committed research misconduct, which included misrepresenting clinical data and duplicating images in a dozen different publications. After a failed attempt to appeal the decision, Ryan resigned.

In April, we covered Ryan’s first two retractions – a 2012 paper in Molecular Microbiology, which cited image errors, and a 2011 paper in Journal of Bacteriology, which cited image duplication.

Now, PNAS has retracted a 2006 paper, which cites potential image duplication as well as “irregularities” in the data.

Here’s the retraction notice for “Cell–cell signaling in Xanthomonas campestris involves an HD-GYP domain protein that functions in cyclic di-GMP turnover:”

“The article must be retracted:” Journal pulls prostate cancer study

A 2016 paper exploring the biology of prostate cancer has been retracted due to figure manipulation.

According to the retraction notice, a reader contacted the journal Clinical Cancer Research in late 2016 with concerns that similar bands appeared multiple times in two images. The editors asked the paper’s corresponding author, Shahriar Koochekpour, about the issue and requested the raw data for the figures. But Koochekpour, based in the Departments of Cancer Genetics and Urology at Roswell Park Cancer Institute in Buffalo, New York, at the time of the study, could not locate the raw data.

Since the lab did not have raw data from such a relatively recent paper, the editors reached out to the research integrity officer at Roswell Park Cancer Institute to investigate. Indeed,  the research integrity officer contacted confirmed that two figures were problematic, and requested the paper be retracted.

Here’s the rather detailed retraction notice, published in July 2017, for “GRM1 is An Androgen-Regulated Gene and its Expression Correlates with Prostate Cancer Progression in Pre-Clinical Models:” Continue reading “The article must be retracted:” Journal pulls prostate cancer study
