Last year, a panel at the University of Tokyo recommended that 43 papers by Kato and colleagues should be retracted. The investigation launched after an anonymous tipster made a video pointing out evidence of image tampering. According to the blog Retraction Watch, Kato’s group has racked up at least 17 retractions so far, and Kato has resigned from his post at the University.

The latest retracted studies appeared in Molecular and Cellular Biology in 1999, 2002, 2007, and 2008. According to Google Scholar, one of the studies, “Purification and identification of p68 RNA helicase acting as a transcriptional coactivator specific for the activation function 1 of human estrogen receptor α,” has been cited 374 times. One of Kato’s coauthors, Hirochika Kitagawa, did not agree two ...
