Perhaps it’s appropriate given the Easter season, but we have learned that Naoki Mori, the Japanese cancer researcher who received a 10-year publishing ban from the American Society of Microbiology (ASM) for imagine manipulation, has published a new paper.
Mori, who was fired and then rehired by the University of the Ryukyus over the scandal, is listed as the senior author on the paper, “Honokiol induces cell cycle arrest and apoptosis via inhibition of survival signals in adult T-cell leukemia,” which appears in the March issue of Biochimica et Biophysica Acta. The journal, an Elsevier title, is an umbrella for nine publications in the biosciences.
Two of Mori’s retracted articles appeared in the Elsevier journals Leukemia Research and Biochemical and Biophysical Research Communications. Read the rest of this entry »
The International Journal of Cancer has retracted seven more articles by the disgraced Japanese researcher, all for the same reasons:
The following article has been retracted through agreement between the first author and several coauthors, the journal Editor in-Chief, Peter Lichter, and John Wiley & Sons, Ltd. … After an investigation the retraction has been agreed due to inappropriate duplication of images and overlap with other published work.
The papers are as follows: Read the rest of this entry »
The retraction total for Naoki Mori continues to rise.
The October issue of Biochemical and Biophysical Research Communications has retracted a 2007 paper by Mori et al for the same issues — manipulated images — that brought down the 20-odd other papers of his since the scandal broke in late December.
Earlier this week we reported on the latest retraction of an article by Naoki Mori, number 21 in a series. We could have waited a few days and saved ourselves some trouble.
The journal Leukemia Research has retracted a 2006 paper by Mori, titled “Curcumin suppresses constitutive activation of AP-1 by downregulation of JunD protein in HTLV-1-infected T-cell lines.” From the notice, which is behind a paywall: Read the rest of this entry »
When we first wrote about Naoki Mori last December, one question we had was why Infection and Immunity, the journal that got the ball rolling in this case, wasn’t retracting a 1999 article by the serial manipulator. Well, it has.
The August issue of the journal, a publication of the American Society of Microbiology — which levied a 10-year ban on Mori for his misdeeds — contains the following retraction notice: Read the rest of this entry »
On second (or third) thought, maybe not: The Journal of Steroid Biochemistry & Molecular Biology has retracted a pair of articles by three Japanese researchers who apparently liked their own work so much they decided to submit it, and submit it—and submit it again.
Here’s the notice for the first paper, a 2004 publication titled “Vitamin D receptor (VDR) promoter targeting through a novel chromatin remodeling complex,” by Shigeaki Kato, Ryoji Fujiki and Hirochika Kitagawa, fairly well-known molecular endocrinologists at the University of Tokyo: Read the rest of this entry »
Lest readers of Retraction Watch had forgotten about Naoki Mori, the cancer researcher who liked his Western blots so much he decided to reuse them — and reuse them some more — he’s back.
The British Journal of Haematology (BJH) has retracted two papers Mori published in that journal, and BMC Microbiology has retracted another, bringing the total of retractions involving his work to at least 19 by our count. [See update at end.]
The BJH issued both retractions online in the end of February, and they’ve since come out in print. Here’s the retraction notice for the first paper, in the BJH (first only because it was published first): Read the rest of this entry »
Naoki Mori, of 16-retraction fame, believes he’s getting his job back at the University of the Ryukyus, which released him in August after learning that the cancer researcher had misused images in many of his publications.
According to a report in ScienceInsider, Mori’s penalty has been reduced to a 10-month suspension, and he will resume his professorship in June. Mori apparently also told Science that some journals “are considering accepting corrected papers,” although he didn’t name them. Read the rest of this entry »
As with the previous Mori retractions, the latest ones — of papers published in 2007 and 2010 — involve unreliable images. Mori, you’ll recall, had recycled control blots from study to study over the years, and was dismissed from his academic post in August.
The 2007 paper, “Activation of hypoxia-inducible factor 1 in human T-cell leukaemia virus type 1-infected cell lines and primary adult T-cell leukaemia cells,” also included a frequent co-author Mariko Tomita, who has been implicated in the deception. It has been cited 15 times, according to Thomson Scientific’s Web of Knowledge. The 2010 article, “Inhibition of Akt/GSK3β signalling pathway by Legionella pneumophila is involved in induction of T-cell apoptosis,” has not yet been cited.
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: Read the rest of this entry »
