A new retraction has appeared in the journal Cell. The article, “DNA-PKcs-PIDDosome: A Nuclear Caspase-2-Activating Complex with Role in G2/M Checkpoint Maintenance,” had initially appeared in February 2009.

There’s helpful but uninformative:
Ivan: What’s the weather like today?
Adam: Sunny.
And then there’s uninformative as served up by the Journal of Biological Chemistry.
We’ve already recounted one teeth-grinding experience with the JBC, a publication of the American Society for Biochemistry and Molecular Biology. The case involved two papers in JBC by Axel Ullrich, an esteemed cancer researcher at the Max Planck Institute in Germany. According to Ullrich, one of his then-postdocs, Naohito Aoki, had manipulated figures that appeared in the papers, necessitating their retraction.
Round two involves another JBC retraction of a 2000 paper by Aoki and co-author Tsukasa Matsuda, titled ‘A cytosolic protein-tyrosine phosphatase PTP1B specifically dephosphorylates and deactivates prolactin-activated STAT5a and STAT5b.’ The paper has been cited more than 100 times, according to Thomson Scientific’s Web of Knowledge.

Graham Ellis-Davies says January 25th was one of the worst days of his life. That was when the journal ChemBioChem retracted an article, published barely two weeks earlier, for a mistake Ellis-Davies blames squarely on himself.
The fallout has been nearly two months of painful self-recrimination, a tattered friendship and, perhaps most significant, he adds, the wasted effort of a postdoc who poured months of research into a now worthless publication. Continue reading Aftermath: Gut-wrenching misstep leads to retraction, frayed feelings and a paperless postdoc
If a paper is retracted, should papers that cite it get retracted, too? We’ve been on the lookout for this kind of move, which we figure is consistent with cleaning up the scientific record. Today, one appears in Nature.
The original paper, “Mediation of pathogen resistance by exudation of antimicrobials from roots,” purported to show how a particular bug evades the immune system of Arabidopsis, a plant commonly used in the lab. It has been cited 51 times, according to Thomson Scientific’s Web of Knowledge.
The retraction notice says that the paper’s conclusions could no longer be supported because one of the key references — a paper in the Journal of Agricultural and Food Chemistry by many of the same authors — had been retracted: Continue reading A Nature chain retraction for Arabidopsis paper, and some unanswered questions
About a year ago, Acta Crystallographica Section E issued a bombshell editorial. The journal was pulling 70 papers from two groups of researchers at the same Chinese university after discovering that the structures they reported had been fakes.
As the editorial explained, the fraud was detected during a routine review of the structures by Ton Spek, of Utrecht University in The Netherlands. According to the editorial: Continue reading Crystal myth: 11 more retractions from crystallography journal after 2010 fakery
We’re continuing to follow the case of Jatinder Ahluwalia. As we reported on Tuesday, Ahluwalia was dismissed from graduate school at the University of Cambridge years before a University College London (UCL) investigation found had renumbered files to deceive a co-author, and had likely sabotaged his colleagues’ work while manipulating his solutions to improve how his results looked. The results of that investigation came to light as part of a Nature retraction.
Ahluwalia now works — and studies plagiarism, in fact — at the school of health and bioscience at the University of East London. We asked Neville Punchard, the school’s dean, whether the university was aware of Ahluwalia’s past. Punchard replied by email: Continue reading University of East London “looking into” Jatinder Ahluwalia’s career
Here at Retraction Watch, we’ve been following the case of Jatinder Ahluwalia with interest. You may recall that an investigation by University College London (UCL) found “beyond reasonable doubt” that Ahluwalia had renumbered files to deceive a co-author. UCL was also “highly confident” that Ahluwalia had messed with his solutions to make his results look better, and sabotaged his colleagues’ work. The report of that investigation was part of a Nature retraction notice.
We’ve now learned that UCL was not the first scene of misconduct by Ahluwalia. Yesterday, we obtained letters by University of Cambridge faculty and administrators describing repeated — and in the words of of one professor, amateurish — data fabrication by Ahluwalia that led to his dismissal from the university’s graduate program.
In a letter dated November 10, 1997, Martin Brand, then Ahluwalia’s PhD advisor, wrote: Continue reading Exclusive: Researcher found guilty of misconduct at UCL had been dismissed from Cambridge for data fabrication
We’re watching a case which appears to involve more than meets the eye.
Molecular Endocrinology has retracted a 2010 study by researchers at the Medical College of Georgia. According to the Spartan retraction notice (we added a link): Continue reading Georgia (well, the Medical College there, anyway) on our minds for a mysterious retraction
We are watching an intriguing case out of the Netherlands, involving a young researcher whose dubious results have led to the retraction of a pair of papers.
The retracted articles, which appeared in 2008 in Cancer Research and the British Journal of Cancer, come from the lab of the prominent Dutch scientist Ed Roos, of the Netherlands Cancer Institute in Amsterdam. Both papers addressed the actions of certain chemokine receptors — molecules on cell surfaces that interact with blood proteins involved in the immune response — on the behavior of tumor cells.
The first author on each paper was Joost Meijer, at the time a graduate student in Roos’ shop.
The retraction notices contain essentially the same information, although in the case of the BJC article — “Effect of the chemokine receptor CXCR7 on proliferation of carcinoma cells in vitro and in vivo” — the letter is quite personal. Dated Jan. 4, 2011, it reads: Continue reading Inability to reproduce Dutch grad student’s data prompts two retractions from the cancer lit
We’ve been honored by all the attention Retraction Watch has been getting for breaking the story of Naoki Mori—the Japanese virologist who recently received a 10-year publishing ban from the American Society of Microbiology over concerns that he manipulated his images. Mori’s retraction count is now up to 11, we’ve been able to report with help from loyal Retraction Watch tipsters.
So in that spirit, we have to give credit to Dennis Normile at ScienceInsider, for advancing the story a bit. As Normile reports today, Nori lost his job at University of the Ryukyus in August and has resorted to “legal mediation” to get it back. (We’ve been unsuccessful in reaching Mori.) Continue reading Mori, now up to 11 retractions, was dismissed in August over fraud matter
