An endocrinologist who resigned from the University of Tokyo last March as the university was investigating his work has retracted another paper.
The following article from the Journal of Bone and Mineral Research, “CDP/Cut Is an Osteoblastic Coactivator of the Vitamin D Receptor (VDR)” by Eiji Ochiai, Hirochika Kitagawa, Ichiro Takada, Sally Fujiyama, Shun Sawatsubashi, Mi-sun Kim,Yoshihiro Mezaki, Yu Tsushima, Ken-ichiro Takagi, Yoshiaki Azuma, Ken-ichi Takeyama, Kazuyoshi Yamaoka, Shigeaki Kato, Takashi Kamimura, published online on December 11, 2009 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors, the journal Editor in Chief, Thomas Clemens, the American Society for Bone and Mineral Research and Wiley Periodicals, Inc. The authors have requested the retraction based on their acknowledgement that several of the figures did not reflect the observations presented.
The study has been cited three times, according to Thomson Scientific’s Web of Knowledge.
This is Kato’s fifth retraction, by our count, including one in Nature and another in Cell. Retraction Watch readers may recall that the investigation into his work was prompted by a whistleblower’s YouTube video.
