Anil Potti failed to disclose corporate ties in yet-to-be-retracted JAMA papers

Anil Potti, the former cancer researcher whose work has become the subject of intense scrutiny that has already led to the retraction of five papers, didn’t tell the Journal of the American Medical Association (JAMA) about two very relevant corporate relationships he had when he published papers there, Retraction Watch has learned.

JAMA has published two papers by Potti and colleagues: 2008’s “Gene Expression Signatures, Clinicopathological Features, and Individualized Therapy in Breast Cancer,” and 2010’s “Age- and Sex-Specific Genomic Profiles in Non-Small Cell Lung Cancer.”

The Cancer Letter, which has been way out front in the Potti case, first reported Potti’s relationships with Eli Lilly and CancerGuide Diagnostics (formerly Oncogenomics, Inc.). As The Chronicle, Duke’s student newspaper, reported last September, the two companies cut their ties with Potti in July 2010 after allegations of misconduct and lying about a Rhodes Scholarship came to light.

But that was after the two papers were published, and Potti had relationships with both since 2006. As The Chronicle notes, he was a director at CancerGuide Diagnostics (formerly Oncogenomics, Inc.), and Continue reading Anil Potti failed to disclose corporate ties in yet-to-be-retracted JAMA papers

Ties that don’t bind: Group retracts parathyroid hormone crystallography paper

The authors of a 2008 paper alleging to have described how a particular protein binds to the parathyroid hormone have retracted it. The paper, “Structure of the Parathyroid Hormone Receptor C Terminus Bound to the G-Protein Dimer Gβ12,” has been cited 12 times, according to Thomson Scientific’s Web of Knowledge. According to the notice: Continue reading Ties that don’t bind: Group retracts parathyroid hormone crystallography paper

A quick Physical Review Letters retraction after author realizes analysis was “performed incorrectly”

One of the authors of a paper in Physical Review Letters has withdrawn it, after someone pointed out an error.

The paper, “Coulomb Forces on DNA Polymers in Charged Fluidic Nanoslits,” was written by Brown University’s Derek Stein and one of his graduate students, Yongqiang Ren. It was published in February of this year, and the retraction ran on July 20.

The notice is forthright: Continue reading A quick Physical Review Letters retraction after author realizes analysis was “performed incorrectly”

The U.S. Department of Health and Human Services’ Office of Research Integrity (ORI) has found that a Boston University cancer researcher made up experiments reported in two papers funded by National Cancer Institute and National Institutes of Health grants. According to the ORI notice:

Sheng Wang, PhD, Boston University School of Medicine Cancer Research Center: Based on the Respondent’s acceptance of ORI’s research misconduct findings, ORI found that Dr. Sheng Wang, who has been an Assistant Professor, Department of Medicine, Boston University School of Medicine Cancer Research Center (BUSM), engaged in research misconduct in research supported by National Cancer Institute (NCI), National Institutes of Health (NIH), grants R01 CA102940 and R01 CA101992.

The two papers were: Continue reading Two papers to be retracted after ORI finds misconduct by Boston University cancer researcher

Marc Hauser resigns from Harvard

University of Louisville investigating work by team under review at Emory

On Tuesday, we reported that Emory University in Atlanta was looking into why a team of former researchers — now at the University of Louisville — had retracted three papers in the Journal of Biological Chemistry (JBC).

Today, we learned that the researchers’ home institution since 2009 is now investigating the work. A spokesperson tells Retraction Watch: Continue reading University of Louisville investigating work by team under review at Emory

Emory looking into circumstances of three new retractions in the JBC

Emory University is looking into why the Journal of Biological Chemistry (JBC) has retracted three papers published by Emory faculty from 2005 to 2007, Retraction Watch has learned. The papers were: Continue reading Emory looking into circumstances of three new retractions in the JBC

Second retraction by Harvard group studying cannabinoids, this one in JBC

Last week, we reported that a group of Harvard researchers had retracted a paper in Blood for “multiple instances of duplicate (redundant) publication of data, text, and images that are nonessential to the paper.” The retraction notice referred to a paper in the Journal of Biological Chemistry (JBC):

The redundancies are between the above-cited Blood article and the following 12 November 2010 article, published in the Journal of Biological Chemistry (JBC): Jiang S, Zagozdzon R, Jorda MA, et al. Endocannabinoids are expressed in bone marrow stromal niches and play a role in interactions of hematopoietic stem and progenitor cells with the bone marrow microenvironment. J Biol Chem. 2010;285(46):35471-35478.

Today, we learned that the JBC paper has also been retracted. The notice, as we’ve come to expect from the JBC, is unhelpful: Continue reading Second retraction by Harvard group studying cannabinoids, this one in JBC

“Nonessential” duplication leads to retraction of Blood cannabinoid paper

The journal Blood has retracted a paper from a group of prestigious Harvard researchers after the article, which appeared in January 2011, was found to have multiple instances of material — text, data and other elements — that had appeared in a previous publication from several of the authors.

The article was titled “Cannabinoid receptor 2 and its agonists mediate hematopoiesis and hematopoietic stem and progenitor cell mobilization.” Its authors included Hava Avraham, a noted cancer researcher, and Jerome Groopman, known for his New Yorker articles about medicine and, scientifically, for his work on cannabinoids and cancer, among other areas.
