Sauer had two papers retracted from Science last year following a university investigation. Here’s the Nature notice for “Histone methylation by the Drosophila epigenetic transcriptional regulator Ash1:”
The authors and the University of California Riverside wish to retract this Letter owing to inappropriate image manipulation in the published figures. The figure panels affected are Figure 1b, d, Figure 2b, e, Figure 3a and Figure 4d. Nature has not received a response from Frank Sauer to approve this retraction.
The paper been cited 220 times, according to Thomson Scientific’s Web of Knowledge.
This is Sauer’s fourth retraction, by our count. In February, he and the university retracted another paper from Molecular Cell following a university investigation that revealed “a significant departure from the accepted practices of Sauer’s research community.” Here’s more from the note for “The Noncoding RNA Mistral Activates Hoxa6 and Hoxa7 Expression and Stem Cell Differentiation by Recruiting MLL1 to Chromatin:”
Molecular Cell is retracting this paper at the request of the Regents of the University of California, Riverside and author Frank Sauer, following correspondence that the editors received from the University and Sauer. This request followed allegations that were subsequently investigated by the Committee on Privilege and Tenure at the University of California, Riverside. The Committee concluded that in Figure S1C of the paper, gel bands were removed to create the image that was submitted for publication. The Committee further concluded that this manipulation constituted data falsification and fabrication as well as a significant departure from the accepted practices of Sauer’s research community.
The Molecular Cell paper has been cited 116 times.
We’ve contacted the university for comment, and will update with anything we learn.
Update, 5:30 p.m. Eastern, 4/16/15: A commenter notes that Sauer had a Cell paper retracted in 1998, making this his fifth.
