Epigenetics Paper Retracted

Nature has retracted a 2002 epigenetics paper from Frank Sauer, then at the University of California, Riverside, for inappropriate manipulation of images, Retraction Watch reports.

The article reportedly showed that Ash1 methylates histones in Drosophila to drive transcription patterns, but the retraction notice from Nature says that a number of figure panels had been inappropriately manipulated. The authors and UC-Riverside sought its retraction, though Sauer didn't respond to approve the retraction, Nature notes.

Retraction Watch adds that this comes on the heels of the retraction last year of two Science papers from Sauer, also for image manipulation, a Molecular Cell retraction in February, and a 1998 Cell retraction.
