A 2015 study by Nobel-Prize-winning neuroscientist Stanley Prusiner is in the process of correction due to a duplicated image in a figure, according to a study co-author.
The paper, “Evidence for alpha-synuclein prions causing multiple system atrophy in humans with parkinsonism,” was published in the Proceedings of the National Academy of Sciences (PNAS) in 2015 and has been cited 497 times, according to Crossref’s Cited-by service.
In December, data sleuth Sholto David, who uses the handle Mycosphaerella arachidis, noted the duplicated image on PubPeer, an online forum for discussing peer-reviewed articles. David previously detected fabricated images in dozens of studies conducted at the Dana-Farber Cancer Institute, which said in January that it was seeking to retract 6 of those papers and correct 31 others as part of an ongoing investigation.
Prusiner’s study co-author Glenda Halliday then responded to David’s PubPeer comment earlier this month, writing that the duplication was “unintentional” and that “the correction to this figure has now been submitted to the journal editor and we hope will be published shortly.” The “correct figure does not change the conclusions of the paper,” continued Halliday, who is professor of neuroscience at the University of Sydney and a middle author on the study.
Halliday posted similar comments on a separate PubPeer thread in which anonymous commenters raised concerns about image duplications in a second study of hers, which does not involve Prusiner or any of the same authors as his 2015 PNAS paper. Halliday declined to comment on the record for this story.
PNAS is aware of the concerns raised about the 2015 Prusiner paper and is “looking into the matter,” journal spokesperson Prashant Nair wrote in an email to The Transmitter.
Prusiner, the study’s first author, did not reply to requests for comment by email and phone. The corresponding author on the paper, Kurt Giles, associate director of the UCSF Pancreas Center, also did not respond to requests for comment by email and phone.
