A well-known scientist at the Massachusetts Institute of Technology who studies longevity has retracted a paper for “numerous examples of unindicated splicing of gel lanes,” as well as other problems.
Guarente told us in March — when we reported that he’d published a mega-correction on another paper — that he had planned to address issues with the paper, “SIRT1 Protects against α-Synuclein Aggregation by Activating Molecular Chaperones,” published in the The Journal of Neuroscience. Now, a retraction note has appeared “at the request of the authors.” It explains:
It was brought to our attention that the Donmez et al., 2012 paper has numerous examples of unindicated splicing of gel lanes and of duplications and inversions of gel images. The prevalence of these occurrences is unacceptable and compels us to retract the paper. We offer our most sincere apologies to readers.
The paper has been cited 80 times, according to Thomson Reuters Web of Science.
Guarente told us he had nothing to add. We could not find current contact information for Donmez.
