Shigeaki Kato up to 38 retractions

Our retraction notice count for Shigeaki Kato, number seven on our leaderboard, has grown to 38.

The former University of Tokyo endocrinologist recently earned another retraction, for a paper in Archives of Biochemistry and Biophysics that contained image manipulation. As we’ve noted before, Kato resigned from the university in 2012 as it investigated his work for misconduct; in 2013 a Japanese newspaper reported that the investigation had found 43 papers from his lab contained “likely altered or forged materials.”

In addition to the new retraction, we’ve dug up four others for Kato from the past few years, plus one correction. Two of the retraction notices mention an investigation at the University of Tokyo.

First, the retraction note for “Multiple co-activator complexes support ligand-induced transactivation function of VDR,” published in December:

A new record: A retraction, 27 years later

jsbmbIn October, we noted the apparent record holder for longest time between publication and retraction: 25 years, for “Retention of the 4-pro-R hydrogen atom of mevalonate at C-2,2′ of bacterioruberin in Halobacterium halobium,” published in the Biochemical Journal in 1980 and retracted in 2005. (Although an author requested that another 52-year-old paper be retracted, it remains untouched in the literature.)

That record has now been broken. Congratulations to the Journal of Steroid Biochemistry and Molecular Biology and the authors of a December 1985 paper, “Increasing the response rate to cytotoxic chemotherapy by endocrine means.” Here’s the notice, which appears in the January 2013 issue of the journal, making 27 years — and a month, if you’re counting: Continue reading A new record: A retraction, 27 years later

Mistaken notice as Ben Gurion researchers retract vitamin D paper for duplication

“Clare Francis,” a prolific pseudonymous Retraction Watch tipster, emailed us recently to flag a retraction in the Journal of Steroid Biochemistry and Molecular Biology (JSBMB) of “The anti-inflammatory activity of 1,25-dihydroxyvitamin D3 in macrophages,” a paper by Amos Douvdevani and colleagues at Ben Gurion University in Israel.

Here’s what we found when we clicked on the notice for the 2007 paper, which has been cited 32 times, according to Thomson Scientific’s Web of Knowledge:

This article has been retracted at the request of the authors, in response to concerns raised by the research committee at the authors’ institution. The authors stated the committee had given approval but the committee states no approval was given. The research committee has asked the authors to retract the paper and the authors have agreed.

That sounded odd to us, since it was unclear what approval was needed, or hadn’t been given. Continue reading Mistaken notice as Ben Gurion researchers retract vitamin D paper for duplication

The new math: How to up your citations (hint: duplication). Plus a correction for Naoki Mori

Here’s a good way to increase the number of times your work is cited: Publish studies three times.

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: Continue reading The new math: How to up your citations (hint: duplication).
