We have an update on the case of Pankaj Dhonukshe, a scientist about whom we reported in November. Utrecht University has found that Dhonukshe, a former researcher at the Dutch university, committed “a violation of academic integrity” in work that led to a number of papers, including one published in Nature and once since retracted from Cell.
Cell update: Co-corresponding author let go from Belgian university; retraction notice language changed
We’ve learned more about the circumstances behind a Cell retraction that we covered last week.
First, one of the two corresponding authors left the institution where he most recently worked. Belgium’s VIB Ghent told us that Pankaj Dhonukshe was no longer employed there and said: Read the rest of this entry »
The article, “Functional dissection of lysine deacetylases reveals that HDAC1 and p300 regulate AMPK,” came from the lab of Jef Boeke, a celebrated biochemist. But a former lab member, Daniel Yuan, who was fired by Hopkins in late 2011 after 10 years at the institution, had repeatedly raised questions about the validity of the findings. Those concerns eventually made their way into the Washington Post, prompting this response from the university. Read the rest of this entry »
Cell is looking into whether the authors of a widely hailed study published last week claiming to have turned human skin cells into embryonic stem cells manipulated images inappropriately, Retraction Watch has learned.
The potential image problems came to light on PubPeer, a site designed to allow for post-publication peer review. A commenter, identified as Peer1, identified “several examples of image reuse which might be of interest to PubPeer members and readers:” Read the rest of this entry »
Alice Ting, winner of an NIH Directors Pioneer Award and named one of Technology Review’s “Innovators Under 35,” published the paper, “Imaging Activity-Dependent Regulation of Neurexin-Neuroligin Interactions Using trans-Synaptic Enzymatic Biotinylation,” in Cell in 2010 along with Amar Thyagarajan.
One of the things we try to do here at Retraction Watch is keep tabs on retracted work that appears again the literature. We did that twice in one day last year, once with a paper about chimps that was retracted from Biology Letters and ended up in the Journal of Human Evolution, and then again with a PLOS ONE paper on on “longevity genes” that had been retracted from Science.
Today, we have another case. Read the rest of this entry »
The senior author on the paper — there were 22 altogether — is Paul Worley of Johns Hopkins. Here’s the notice for “Enhanced Polyubiquitination of Shank3 and NMDA Receptor in a Mouse Model of Autism:” Read the rest of this entry »
Shigeaki Kato, an endocrinology researcher at the University of Tokyo who retracted a paper late last month, has resigned amidst an investigation into whether he committed misconduct, Japanese media outlets are reporting.
According to the reports, the university has been investigating Shigeaki Kato and his group, affiliated with the Institute of Molecular and Cellular Biosciences, for scientific misconduct. The investigation was prompted by an outside whistleblower’s allegations in January about 24 of Kato’s papers. The whistleblower claimed that the papers manipulated and reused data improperly, and created a YouTube video to spread the word, as ScienceInsider reported earlier this year.
One of the 24 papers, Read the rest of this entry »
