“[W]e can learn from these bad actors:” Trail of retractions follows former Vanderbilt researcher’s fraud
Authors have retracted three papers from the Journal of Physiology because they contained “falsified or fabricated data.”
The papers, which address calcium signaling in heart muscle cells, are among the six pegged for retraction after an Office of Research Integrity (ORI) investigation into one of the authors, Igor Dzhura, formerly of Vanderbilt University. The ORI found that Dzhura had committed an enormous amount of fraud, involving dozens of faked images and more.
Dzhura was fired from a job at Novartis in November after the company discovered that his application had included the fraudulent work.
The three retracted Journal of Physiology papers and their citation figures, courtesy of Thomson Scientific’s Web of Knowledge, are: Read the rest of this entry »
A University of Minnesota former chemistry graduate student has been banned from receiving federal funding for five years based on “a preponderance of the evidence that the Respondent intentionally and knowingly engaged in research misconduct.”
Venkata J. Reddy appears to have manipulated findings in one R01 grant application. In recent years, bans are less common than having research supervised. What’s also unusual is that the sanction appeared to have begun two years ago, in 2013, because it lifts August 26, 2018. The report, which is scheduled to published tomorrow in the Federal Register, says the debarment has a “joint jurisdiction,” suggesting another agency may be involved. [See first update at end of post.]
According to the ORI notice, Reddy “intentionally and knowingly engaged in research misconduct by falsifying and/or fabricating data that was provided to his mentor” for an R01 application to the National Institute of General Medical Sciences (NIGMS). More specifically: Read the rest of this entry »
Nasser Chegini, the former University of Florida professor currently under investigation by the Office of Research Integrity (ORI), has now had eight papers retracted.
The eighth paper, in the journal Reproductive Biology and Endocrinology, is about the effect of a compound used during fertility treatments on Smads, signaling molecules that carry messages from TGF-beta receptors to the nucleus. It’s being retracted disappeared due to the discovery of data that “have been fabricated or falsified by the last author” — namely, Chegini.
Here’s more from the notice for “Gonadotropin releasing hormone analogue (GnRHa) alters the expression and activation of Smad in human endometrial epithelial and stromal cells:” Read the rest of this entry »
Teresita Briones, a former nursing professor at Wayne State University in Detroit who studied neuroscience, manipulated images in five papers, according to the Office of Research Integrity.

Ryousuke Fujita, a former Columbia University postdoc who admitted to having faked the findings of a 2011 Cell paper in a retraction notice last year, also faked the results of a 2013 Nature paper, according to a new report from the Office of Research Integrity (ORI).
Fujita’s work, in conjunction with Asa Abeliovich, was widely hailed as a significant step forward, a way to turn skin cells into brain cells. But the story began falling apart when the Cell retraction said that he “acknowledged inappropriately manipulating image panels and data points, as well as misrepresenting the number of repeats performed.”
The ORI’s findings in the case also involve a 2013 Nature paper, “Integrative genomics identifies APOE ε4 effectors in Alzheimer’s disease,” and a paper never published. Fujita, according to the ORI: Read the rest of this entry »
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.
