Two more retractions have popped up for Nasser Chegini, the former University of Florida professor currently under investigation by the Office of Research Integrity (ORI).
Both retractions appear in the Journal of Clinical Endocrinology & Metabolism. The notices indicate that an investigation report from the University of Florida “found substantial data misrepresentation” in two JCEM articles about Smads, signaling molecules that carry messages from TGF-beta receptors to the nucleus.
Here’s the notice for “The Expression of Smads in Human Endometrium and Regulation and Induction in Endometrial Epithelial and Stromal Cells by Transforming Growth Factor-Beta” ( ):
The former director of the X-ray crystallography lab at the National Institute of Arthritis and Musculoskeletal and Skin Diseases, part of the National Institutes of Health, who was found by the Office of Research Integrity to have faked findings in three papers, is once again earning a government salary, this time as a patent examiner, Retraction Watch has learned.

A former researcher at the University of Pittsburgh inflated the number of mice used in his experiments, and faked data in a number of images in a paper reporting the results, according to the Office of Research Integrity (ORI).

A postdoc at the Oklahoma Medical Research Foundation faked data in a submitted paper and in a grant application, according to a new report from the Office of Research Integrity.
The stories behind several recent inscrutable retraction notices became a bit more clear today when the Office of Research Integrity (ORI) issued findings in cases involving former researchers at the University of Chicago and the University of California, San Francisco.
The Office of Research Integrity (ORI) has sanctioned Kaushik Deb, a former post-doc at the University of Missouri-Columbia, who “engaged in misconduct in science by intentionally, knowingly, and recklessly” fabricating data in papers in both Science and Nature (which ultimately rejected his manuscript).
Deb was big news in 2007, when Science retracted his paper. Articles about the case appeared in many outlets, including The Scientist and USA Today. At the time, Missouri’s research integrity officer, Rob Hall, told the Columbia Tribune that: Read the rest of this entry »
A former Vanderbilt University biomedical engineer committed fraud on a massive scale, according to a new Office of Research Integrity (ORI) report.
Igor Dzhura is banned from receiving federal funding for three years, and is retracting six papers, which have been cited more than 500 times. Since leaving Vanderbilt, he has worked at SUNY Upstate Medical University, and now works at Novartis.
According to the ORI, Dzhura was a busy boy at Vanderbilt, faking images and drastically inflating the number of experiments he conducted by duplicating computer files and saving them in nested folders. The total body count from his work includes: Read the rest of this entry »
A paper by a former postdoc at MD Anderson Cancer Center who “admitted to knowingly and intentionally falsifying” a figure has been retracted.
In August, the Office of Research Integrity announced that it had sanctioned Jun Fu for faking data in a study of the results of a mouse study of NVP-HSP990, a Novartis compound designed to fight brain tumors. Here’s the notice for the study in question, published in Cancer Research:

The Office of Research Integrity (ORI) has ruled in a case we’ve been following for nearly two years — and which seems to have been launched after Retraction Watch readers took a careful look at figures from what appeared to be an unrelated case.
Takao Takahashi and Makato Suzuki, both former postdocs at a cancer research center at UT-Southwestern, both “knowingly, intentionally, and recklessly falsified data” in a total of 10 papers, according to the ORI. Takahashi, now at Gifu University in Japan, was responsible for fakery in four papers, while Suzuki, now at Kumamoto University Hospital, also in Japan, falsified data in six.
We reported on the retraction of the four Takahashi papers, and one of the Suzuki papers, in November 2012. At that time, Adi Gazdar, the head of the lab where the researchers worked, told us that
