When retraction notices and expressions of concern appear, particularly those that are opaque, we try our best to find out what’s behind them, whether it’s better explanations or the steps that led to moves. Today, we have one story in which we’ve been able to learn a lot more than usual.
In April, Bas van Steensel, Wendy Bickmore, Thomas Cremer, and Kerstin Bystricky sent a letter to about 80 leading labs in nuclear organization and steroid receptor biology. It began (we’ve added some relevant links): Read the rest of this entry »
Sinead Miggin, a biologist at the National University of Ireland Maynooth, has withdrawn two papers from the Journal of Biological Chemistry (JBC) and has corrected another paper, in the Proceedings of the National Academy of Sciences (PNAS).
Here’s the opaque JBC notice for “14-3-3ϵ and 14-3-3σ inhibit Toll-like receptor (TLR)-mediated proinflammatory cytokine induction,” a paper first published in November 2012: Read the rest of this entry »
The paper, “The requirements for natural Th17 cell development are distinct from those of conventional Th17 cells,” was initially published in September 2011 and has been cited 25 times, according to Thomson Scientific’s Web of Knowledge. First author Jiyeon Kim was an MD-PhD candidate at the University of Pennsylvania until this year, according to a LinkedIn profile.
An article first published online May 16th by a group of researchers at Brown University was retracted on June 1st, apparently because a new and better method for analyzing the data was developed…at some point.
The timeline is not exactly clear from the retraction, though we’ve reached out to the author and publisher and will update with any new information.
Here’s the (paywalled) notice for “High-level production of 3-hydroxypropionatein Escherichia coli and Saccharomyces cerevisiae by introducing part of the 3-hydroxypropionate/4-hydroxybutyrate cycle from Metallosphaera sedula”:
A pair of researchers at the University of Maryland have retracted a third paper.
Here’s the unhelpful Journal of Biological Chemistry notice for “Inhibitor of Nrf2 (INrf2 or Keap1) protein degrades Bcl-xL via phosphoglycerate mutase 5 and controls cellular apoptosis,” by Suryakant Niture and Anil Jaiswal: Read the rest of this entry »
A year after an ORI report discredited the work of former University of Washington in Seattle researcher Andrew Aprikyan, one of the papers named in the report has finally been retracted.
