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The acknowledgement was prompted by our query earlier this week about a 2008 paper from Hertl’s group that had been retracted by the journal Immunology.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This paper has been retracted by the author because of legal issues.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.

From the notice: Continue reading “Representative” image in liver paper leads to retraction

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

Another G&D paper retracted, this one for faked data

Genes & Development (G&D) — a journal published by Cold Spring Harbor Laboratory that published only its second retraction in its 24-year history a few weeks ago, has published another. The study, “PRMT1-mediated arginine methylation of PIAS1 regulates STAT1 signaling,” was published in 2009 and has been cited 22 times, according to Thomson Scientific’s Web of Knowledge.

The retraction notice places the blame squarely on first author Susanne Weber, who was a graduate student at the time the study was published and signed the retraction. The G&D notice, in the July 1, 2011 issue, reads: Continue reading Another G&D paper retracted, this one for faked data
