These latest notices move the count up to 8.5 retractions for Potts-Kant and 7.5 for Foster (counting the partial retraction as 1/2), along with the correction for both. In both cases and in a familiar note from previous retractions, authors found “potential discrepancies” between two sets of data (partial retraction) and study figures that weren’t “reliable” (retraction).
The retraction comes after the authors discovered problems with three of the study figures. In the corrected paper, the authors were able to validate some of their findings after repeating the experiments, but retracted two of the study figures that they were “unable to verify.”
Authors were unable to replicate the experiments after “concerns about the initial data from the animal physiology laboratory” led them to reanalyze source data, according to the note in Environmental Health Perspectives. The comparison showed “potential inconsistencies in the data,” which “significantly impact the overall conclusions of the manuscript.” Similar issues appear to have felled the pair’s other papers, including the other two recent retractions in the American Journal of Respiratory and Critical Care Medicine and the American Journal of Physiology – Lung Cellular and Molecular Physiology — but in the latter case, the discrepancies don’t affect the conclusion.
Potts-Kant was arrested on embezzlement charges in 2013. Authorities alleged that she stole almost $15,000 from Duke University.
Environmental Health Perspectives posted a retraction in July, for a 2012 paper that looked at the molecular underpinnings in airways that react to ozone.
Here’s the full notice:
Biochemical Journal has pulled a 2006 paper for an undisclosed “background subtraction box” in an image – which, if you take a not-particularly-close look at the figure to the right, means somebody added a black rectangle over the control lane.
It’s unusual for us to post obituaries on Retraction Watch — we’ve published just one so far in three-and-a-half years — but we wanted to pause for a moment to note the passing of a tireless crusader for transparency and accountability whose electronic path crossed with ours a number of times since 2012 because of our shared interest in the case of Anil Potti.
We learned of the death of Ed Rickards this weekend while Ivan was attending ScienceOnline 2014. The Duke Chronicle, the university’s student newspaper, reported on February 5: Read the rest of this entry »
We’ve seen a lot of retraction notices for work by Anil Potti — 10, to be precise, along with 7 corrections and one partial retraction notice. As notices go, they tend to be pretty complete. So when we saw one in CHEST for this 2008 abstract, we were expecting something similar.
Instead, we were confused.
Lead author of major breast cancer study announced at ASCO co-authored two corrected papers with Anil Potti
One of the biggest stories so far out of the American Society of Clinical Oncology (ASCO) meeting that just ended in Chicago was that of T-DM1, which, according to Ivan’s Reuters colleagues, “extended the length of time breast cancer patients lived without their disease getting worse.” (The news was even the subject of an embargo break.)
A partial retraction has joined the ten retractions and five corrections of Anil Potti’s papers, this one of a 2008 paper in Molecular Cancer Therapeutics. The move comes 14 months after the retraction of the Nature Medicine paper upon which much of the Molecular Cancer Therapeutics paper was based.
Anil Potti and his colleagues have retracted another paper, “Characterizing the Clinical Relevance of an Embryonic Stem Cell Phenotype in Lung Adenocarcinoma,” originally published in the December 15, 2009, issue of Clinical Cancer Research.
Anil Potti can add two corrections to his less-and-less impressive publication record. The mega-corrections — part of what we are close to being ready to call a trend in errata notices — in the Journal of Clinical Oncology (JCO) are, however, quite impressive, each with at least a dozen points.
