This blog post is not an accusation of misconduct, and reflects my personal opinion.
This paper has it all. The authors are from Stanford University’s School of Medicine and Harvard Medical School. It was published in 2002 in Nature Medicine, and has been cited over 900 times, as per Google Scholar. It even received a prestigious F1000 Recommendation. And it was supported by six NIH grants.
Five years ago, in 2014, I reported three papers from the same lab with possible image duplications to the journals in which they had been published. One of these papers has since then been corrected – although I argued in a previous post about this paper that a retraction might have been a better decision. The other two papers are still untouched, unfortunately.
Since the journals and authors had had 5 years to respond, I posted my concerns about these three papers on PubPeer, so that at least researchers with the PubPeer extension can see that they have been “flagged”. I also found a couple more papers from this lab – headed by Dr. Xuetao Cao – that appeared to have problems and I posted these as well.
And then someone pointed out that the senior author on these papers was one of the top immunologists in China.
