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

Authors retract two JBC papers on how heart rhythms go awry; Montreal Heart Institute looking into why

The authors of two Journal of Biological Chemistry (JBC) studies of the molecular underpinnings of hearts whose rhythms have gone awry have retracted the papers, for reasons that are not completely clear.

The two papers are  “MicroRNA miR-133 represses HERG K+ channel expression contributing to QT prolongation in diabetic hearts,” published in 2007, and “Down-regulation of miR-1/miR-133 contributes to re-expression of pacemaker channel genes HCN2 and HCN4 in hypertrophic heart,” published in 2008.

This being the JBC, the retraction notices in the August 12, 2011 issue say nothing: Continue reading Authors retract two JBC papers on how heart rhythms go awry; Montreal Heart Institute looking into why

Another retraction for Milena Penkowa, this one in Experimental Physiology

There’s another retraction in the the complicated case of Milena Penkowa, the former University of Copenhagen researcher being investigated for scientific misconduct and misuse of grant funds. The paper, in Experimental Physiology, was titled “Exercise-induced metallothionein expression in human skeletal muscle fibres” and was published online in January 2005.

It’s the second retraction for Penkowa, who did not sign either of them. According to the notice: Continue reading Another retraction for Milena Penkowa, this one in Experimental Physiology

University investigating leading German derm lab that retracted Immunology paper

The laboratory of Michael Hertl, a German dermatology researcher with an international reputation, is under investigation for possible misconduct, according to a legal official at Hertl’s institution, Philipps-Universitat Marburg.

The acknowledgement was prompted by our query earlier this week about a 2008 paper from Hertl’s group that had been retracted by the journal Immunology. According to the July 25 retraction notice: Continue reading University investigating leading German derm lab that retracted Immunology paper

Sebastiani group retracts genetics of aging study from Science

When a group of researchers last year claimed to have found a “genetic signature” to identify people likely to live to 100, they were questioned immediately. Now they’ve retracted the controversial paper —  but continue to stand behind their assertion.

The paper had been the subject of an “Expression of Concern” in November. The retraction notice in this week’s Science: Continue reading Sebastiani group retracts genetics of aging study from Science

Cryptic “legal issues” lead to retraction of paper about potential Novartis alcohol abuse drug

Readers of this blog by now know that if there’s one thing that really gets us going, it’s obfuscation. So it shouldn’t be surprising that the following retraction notice from the journal Psychopharmacology, made us particularly batty:

This paper has been retracted by the author because of legal issues.

The notice refers to  “Selective activation of the metabotropic glutamate receptor subtype 7 “mGluR7” attenuates acquisition, expression, and reinstatement of ethanol place preference,” was published online in late June by Amine Bahi under the heading “Original Investigation.”

Bahi is in the department of anatomy at United Arab Emirates University. He has also held positions at Yale and the University of Fribourg in Switzerland. Among his publications is one that involved a collaborator from Novartis (more on that in a moment). Continue reading Cryptic “legal issues” lead to retraction of paper about potential Novartis alcohol abuse drug

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

Authors retract Nature Medicine cystic fibrosis paper after some results don’t hold up

The authors of a Nature Medicine study published online in September about the behavior of white blood cells in cystic fibrosis have retracted the paper, saying that further experiments suggested the original results were unreliable. According to the notice: Continue reading Authors retract Nature Medicine cystic fibrosis paper after some results don’t hold up

“Representative” image in liver paper leads to retraction

The journal International Immunology has retracted a 2007 article, “Amelioration of hepatic fibrosis via beta-glucosylceramide-mediated immune modulation is associated with altered CD8 and NKT lymphocyte distribution,” by a group of Israeli liver researchers whose manuscript included a composite image that didn’t quite call itself such.

The study, by scientists at Hadassah Medical Center in Jerusalem, purported to show that a soy-derived compound could reduce liver disease in mice. It has been cited 17 times, according to Thomson Scientific’s Web of Knowledge. The journal is published by Oxford and the Japanese Society for Immunology.
