An investigation at St. Jude Children’s Hospital into “irregularities” in a figure featured in a neuroblastoma paper has concluded that the image was fabricated. The paper, published in Surgery in 2012, was retracted on Friday.
Here’s the full retraction notice for “Liposome-encapsulated curcumin suppresses neuroblastoma growth through nuclear factor-kappa B inhibition:”
This article has been retracted at the request of the Editors and Authors. The irregularities in Figure 3E have been investigated by the co-authors and St. Jude Children’s Research Hospital, and the investigation concluded that the image was fabricated. We therefore retract the publication. We apologize to the scientific community for any inconvenience resulting from the publication and retraction of this manuscript.
The paper — which presented the molecular underpinnings of how a form of curcumin could reduce the growth of neuroblastoma — has been cited 12 times, according to Thomson Scientific’s Web of Knowledge.
Michael Sarr at the Mayo Clinic, one of the editors of Surgery, declined to comment.
Last year, a commenter on PubPeer raised concerns over Figure 3E, the very image that the investigation determined was fabricated. The commenter points to other papers by last author Andrew Davidoff at St. Jude that have also been discussed on the site, such as a 2007 paper, this 2012 paper, and another 2013 paper in PLOS ONE.
We’ve contacted Davidoff and first author Wayne Orr, now at the University of Mississippi Medical Center. We’ve also asked representatives of St. Jude’s Children’s Hospital for more information about the investigation.
