The latest retraction for Tina Wenz in the Journal of Applied Physiology mentions the probe at the University of Cologne in Germany, which recommended retracting six of her papers. One had already been retracted by the time the report was released; last month, we reported that two others had been pulled. Now, we’ve come across a fourth.
The probe into Tina Wenz by the University of Cologne in Germany, her former employer, recommended that six of her papers — which have induced some chatter on PubPeer — should be retracted. One of these papers was pulled by Cell Metabolism last year. Now, Cell Metabolism has pulled another of Wenz’s papers, and she has also lost another study published in the Proceedings of the National Academy of Sciences (PNAS), which was previously corrected.
The University of Cologne has conducted an investigation into the research of Tina Wenz, and determined that six papers should be pulled due to scientific misconduct.
One of the six papers was already retracted last year by Cell Metabolism, which cited reused northern and western blot band images in two figures.
The other six papers are: Read the rest of this entry »
The authors of a Cell Metabolism paper are pulling it after discovering blot images that “appear more than once in independent and unrelated experiments.”
Just how the duplication occurred in the 2009 paper — about transcription of mitochondrial DNA — remains a mystery, the authors note:
…the reasons for the errors are still under investigation…
Meanwhile, we’ve learned that the last author on the paper — Carlos Moraes of the University of Miami — has requested a retraction for another 2013 paper in Mitochondrion, also co-authored by Tina Wenz at the University of Cologne in Germany. That paper is among multiple publications co-authored by Moraes and Wenz that have been flagged on PubPeer.
We’ve reached out to the parties involved, and received a warning from an attorney representing Wenz that if we write about Read the rest of this entry »
