An Ohio State University (OSU) professor intentionally manipulated the data in six articles published from 2004–10 (1–6), according to a report published in the Federal Register by the Office of Research Integrity (ORI) of the U.S. Department of Health and Human Services on December 26, 2012.
Elton’s research focused on the role of microRNA expression and gene regulation in cardiovascular diseases. In a 2007 article published in The Journal of Biological Chemistry, Elton and colleagues reported that a gene polymorphism associated with cardiovascular disease interferes with microRNA attenuation of that gene’s expression, possibly leading to disease (4). Since its publication, the article has been cited 139 times according to Thomson Reuters Web of Knowledge. The article is among those containing manipulated figure data; it is slated for retraction.
The research misconduct findings are the result of two OSU investigations and an oversight review by the ORI. OSU was tipped off to Elton’s research misconduct by an anonymous source who contacted ORI officials in July 2010, according to an OSU statement released by senior director of Research and Innovation Communications, Jeff Grabmeir.
“Ohio State confirmed misconduct by Dr. Elton and has fully cooperated with the ORI over the course of its investigation. The investigation showed that Dr. Elton falsified and/or fabricated data from Western blots, a standard laboratory technique used to detect proteins,” explained Grabmeir’s statement.
In the end, Elton has agreed to exclude himself from contracting or subcontracting with any federal agencies for three years. In addition, he has been removed from an advisory capacity to the U.S. Public Health Service for three years from November 26. He has also agreed to request that the six papers containing falsified or fabricated data be retracted.
In addition, OSU has imposed sanctions of its own, which include a written reprimand, mandatory counseling on research misconduct, and complete formal training on research ethics. Elton will also be prohibited from supervising undergraduate or graduate students, postdoctoral trainees, or laboratory technicians for three years. Also, all manuscripts and grant applications involving Elton’s participation will require review and approval by university officials prior to submission for the next five years.
“Ohio State University takes allegations of research misconduct seriously and will continue to work diligently to protect the integrity of research produced by members of the university community,” the statement read.
Neither Elton nor ORI directors replied to requests for comment.
