And that’s 14: More (and more) Mori retractions, as Japanese cancer journal pulls three papers

Naoki Mori

The steady drip-drip-dripping sound you hear from the cancer literature these days comes from the stream of retractions involving studies by Naoki Mori, the now jobless scientist whose work on cancer viruses appears to be evaporating before our eyes.

Cancer Science, which used to be called the Japanese Journal of Cancer Research,  has retracted three more of Mori’s papers, each of which, according to the journal, contained multiple unreliable images. That brings the tally of retractions involving Mori’s articles to 14 by our count, an impressive number by any measure. Mori has more than 50 papers to his name, however, so it’s possible that the number of retractions will grow.

Here are the latest retractions: Continue reading And that’s 14: More (and more) Mori retractions, as Japanese cancer journal pulls three papers

Sixth Bulfone-Paus retraction accepted

Silvia Bulfone-Paus

A journal has accepted the sixth retraction of a paper co-authored by Silvia Bulfone-Paus, the Research Centre Borstel announced late last week. Borstel has been investigating allegations that two of Bulfone-Paus’s former postdocs manipulated images.

The paper, in the Scandinavian Journal of Immunology, is titled Continue reading Sixth Bulfone-Paus retraction accepted

Cracking the Mori case: A reviewer describes how manipulated images came to light

Naoki Mori

We’ve had two questions since learning of the fraud case involving Naoki Mori: Who discovered the manipulations? And how?

We now have answers. We recently received an e-mail from a researcher who specializes in Mori’s field — cancer viruses — and who claims to have been a reviewer of a paper he submitted early last year to a journal in his field. (We’re obscuring some details to maintain our source’s anonymity.)

During what turned out to be a “painful” review of the manuscript: Continue reading Cracking the Mori case: A reviewer describes how manipulated images came to light

Lab gadfly PETA pressures AACR, gets retraction from sanctioned scientist

People for the Ethical Treatment of Animals (PETA) may not be on most scientists’ list of Facebook friends, but we’re grateful to them for a hat tip. Several days ago, we were approached by Justin Goodman, associate director of PETA’s laboratory investigations department, with a new twist on an old story.

First, a little history: In September 2009, the Office of Research Integrity sanctioned an ex-Vanderbilt cancer researcher named Nagendra S. Ningaraj. According to the agency, Ningaraj Continue reading Lab gadfly PETA pressures AACR, gets retraction from sanctioned scientist

Mori, now up to 11 retractions, was dismissed in August over fraud matter

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

Four more Bulfone-Paus paper retractions accepted

About two weeks ago, we reported on the first retraction of a paper co-authored by Silvia Bulfone-Paus, whose work at her Research Center Borstel lab is being investigated for misconduct. On Friday, Borstel announced that journals had accepted four more retractions of papers by Bulfone-Paus’s group.

Three of those papers are in the Journal of Immunology (citations according to Thomson Scientific’s Web of Knowledge): Continue reading Four more Bulfone-Paus paper retractions accepted

Fraud by Naoki Mori claims another paper, this one in a journal whose board he sits on

Late last month we wrote about a handful of retractions involving Naoki Mori, a promising Japanese cancer researcher who appears to have built a CV with the help of fabricated evidence.

The fraud earned Mori a 10-year publishing ban from the American Society of Microbiology, which publishes Infection and Immunity. There were two other retractions in Blood, from the American Society of Hematology.

Now, another journal has joined the party. Continue reading Fraud by Naoki Mori claims another paper, this one in a journal whose board he sits on

Paper by Silvia Bulfone-Paus to be retracted

At least one of the dominoes may be falling from a scandal at Research Center Borstel.

Retraction Watch has learned that one of six papers that an investigation found to include data manipulation will be retracted by the Journal of Leukocyte Biology. The paper, “ATP induces P2X7 receptor-independent cytokine and chemokine expression through P2X1 and P2X3 receptors in murine mast cells,” includes Silvia Bulfone-Paus as a co-author. The retraction notice will appear in the March issue of the journal, editor Luis Montaner told Retraction Watch today.

Bulfone-Paus is at the center of a complex case, and we’ll refer you to Nature‘s excellent coverage. As Nature reported last month: Continue reading Paper by Silvia Bulfone-Paus to be retracted

Update on Small retraction: Co-author says failed follow-up led to detection of tech’s fraud

We have a little more information on the lab-tech case out of the University of Chicago that we reported on last week. A brief summary: The journal Small retracted a 2007 paper on a method of producing insulin-secreting cells after one of the co-authors, a technician named Matthew Connors, was found to have fabricated a key figure. Connors has had a long career as a lab tech and his name has appeared on several published articles.

Reached by e-mail, Milan Mrksich, a chemistry professor at Chicago and a co-author of the retracted paper– as well as an investigator for the Howard Hughes Medical Institute — told us that the fraud surfaced during follow-up research: Continue reading Update on Small retraction: Co-author says failed follow-up led to detection of tech’s fraud

Japanese virologist hit with publishing ban after widespread data manipulation

A leading Japanese virologist has received a 10-year publishing ban from the American Society of Microbiology after many of his published articles were found to have evidence of data manipulation.

In its January 2011 issue, Infection and Immunity, an ASM title, is retracting five articles by the researcher, Naoki Mori, of the University of Ryukyus in Okinawa. The articles, published between 2000 and 2009, involve work on Helicobacter pylori which Nori conducted with co-authors from the United States and elsewhere. Some of the studies listed co-authors from drug companies, including Merck and Boehringer Ingelheim, although it’s not clear whether the companies helped support any of the research.

Despite the impending holidays, Ferric Fang, editor of Infection and Immunity, graciously and quickly replied to our request for comment yesterday (as he has before, about another paper in Nature involving fraud): Continue reading Japanese virologist hit with publishing ban after widespread data manipulation
