In June, we reported on a retraction in Current Biology that came after a number of PubPeer commenters suggested that the authors had engaged in figure manipulation, memorably comparing watching the published videos to playing the old-school arcade game “Space Invaders.”
Now a second paper from the same team has been retracted from Biology Open after the authors “were unable to repeat the results.” The journal was unable to get in touch with first author Livana Soetedio, whom the University of Illinois at Chicago found had fabricated the data and images in both publications.
A paper by a former postdoc at MD Anderson Cancer Center who “admitted to knowingly and intentionally falsifying” a figure has been retracted.
In August, the Office of Research Integrity announced that it had sanctioned Jun Fu for faking data in a study of the results of a mouse study of NVP-HSP990, a Novartis compound designed to fight brain tumors. Here’s the notice for the study in question, published in Cancer Research:

The first retraction, in August of 2013, got a lot of attention for how poorly faked the figures were. At the time, an expression of concern was issued on the paper that has just been retracted.
Today, we exchanged emails with Jeffery Botkin, the research integrity officer at the University of Utah, who ran the investigation into the misconduct. He summarized the report for us below. Read the rest of this entry »
The reason: Image manipulation — which the authors say didn’t materially affect the conclusions of the paper.
The article, “FAK mediates the activation of cardiac fibroblasts induced by mechanical stress through regulation of the mTOR complex,” came from a group led by Ana Paula Dalla Costa, from the State University of Campinas.
Here’s the notice that will appear for “Human renal stem/progenitor cells repair tubular epithelial cell injury through TLR2-driven inhibin-A and microvesicle-shuttled decorin“: Read the rest of this entry »
Former University of Tokyo researcher Shigeaki Kato has notched his 26th, 27th, and 28th retractions, all in Nature Cell Biology. The three papers have been cited a total of 677 times.

Two of the three papers by Bijan Ahvazi were published in 2004, and later retracted in 2007, while the other was rejected: Read the rest of this entry »
Molecular Vision has issued “full retractions” for a trio of articles by a group of eye researchers. All of the articles were led by Azza El-Remessy, director of the University of Georgia College of Pharmacy’s clinical and therapeutic graduate program.
As much as that is, there might be more still with this case.
The first paper, from 2000, was titled “Regulation of interphotoreceptor retinoid-binding protein (IRBP) gene expression by cAMP in differentiated retinoblastoma cell.” Its abstract states: Read the rest of this entry »
A late researcher in Italy who has already been blamed for image manipulation in a PLOS ONE retraction notice has had two more papers retracted, both from Free Radical Biology and Medicine.
The paper, “The Effect of Soluble RAGE on Inhibition of Angiotensin II-Mediated Atherosclerosis in Apolipoprotein E Deficient Mice,” came from a group of researchers in South Korea.
It purported to show that: Read the rest of this entry »
