The University of Tokyo panel investigating the work of a former professor there, Shigeaki Kato, has recommended the retraction of 43 of his group’s articles, according to a report in the Asahi Shimbun newspaper.
If the papers are indeed retracted, Kato, who already has at least five articles subject to an expression of concern and five retractions, would be fifth on the list of most retractions for a single author, by our unofficial tally. His fellow countryman, Yoshitaka Fujii, continues to hold the lead at what appears to be 183, followed by Joachim Boldt (~89), John Darsee (~83), and Diederik Stapel, at 53. [See note at end.]
The Asahi report quotes Kato — who has received some $20 million in government funding for his work — as acknowledging problems with the data in his studies: Read the rest of this entry »
An endocrinologist who resigned from the University of Tokyo last March as the university was investigating his work has retracted another paper.
Shikeagi Kato, an endocrinologist formerly of the University of Tokyo who resigned on March 31 amidst an investigation into his work, has retracted another paper, this one in Nature.
Shigeaki Kato, an endocrinology researcher at the University of Tokyo who retracted a paper late last month, has resigned amidst an investigation into whether he committed misconduct, Japanese media outlets are reporting.
According to the reports, the university has been investigating Shigeaki Kato and his group, affiliated with the Institute of Molecular and Cellular Biosciences, for scientific misconduct. The investigation was prompted by an outside whistleblower’s allegations in January about 24 of Kato’s papers. The whistleblower claimed that the papers manipulated and reused data improperly, and created a YouTube video to spread the word, as ScienceInsider reported earlier this year.
One of the 24 papers, Read the rest of this entry »
A while back (last June, to be precise), we wrote about a group of Japanese endocrinologists who found a creative way to up their citation counts using duplicate publication. At the time, the researchers were docked a 2004 paper in the Journal of Steroid Biochemistry & Molecular Biology that had self-plagiarized extensively from a 2003 article in Cell.
Well, skeptics of this new math take heart: The group’s publication total has fallen yet again. Turns out that 2003 paper — which has been cited 160 times, up from 144 when we checked last year, according to Thomson Scientific’s Web of Knowledge — wasn’t quite up to snuff, either.
According to the retraction notice for the article, ”The Chromatin-Remodeling Complex WINAC Targets a Nuclear Receptor to Promoters and Is Impaired in Williams Syndrome:” 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 »
