Retraction for stem cell scientist facing misconduct inquiry

Here’s a retraction from Stem Cells and Development that we’re just now getting around to covering. The paper, “Non-viral reprogramming of skeletal myoblasts with valproic acid for pluripotency,” appeared in June 2012 in a preliminary online form and was written by a group at the University of Cincinnati. As the retraction notice states: Continue reading Retraction for stem cell scientist facing misconduct inquiry

“Ambiguities in the presentation of some of the data” lead to an ambiguous retraction notice

Sometimes, authors and journals editors seem to think a bit of mystery is a good thing. Take a recent retraction in Brain.

Here’s the notice for “Selective impairment of hand mental rotation in patients with focal hand dystonia:” Continue reading “Ambiguities in the presentation of some of the data” lead to an ambiguous retraction notice

Italian cancer specialist facing criminal investigation for misconduct

Institute of Endocrinology and Experimental Oncology

A leading Neapolitan cancer researcher is under criminal investigation for fraud, the Italian press is reporting.

Although we have only rough translations of the story, it seems the researcher, Alfredo Fusco, of the National Council of Research’s Institute of Experimental Endocrinology and Oncology, has been accused of manipulating images in published studies and to strengthen the case for grants from the Italian Association for Cancer Research (AIRC).

The case covers eight papers published between 2001 and 2012, according to the media reports. We don’t know the specifics of the eight articles, nor why none appears yet to have been retracted. In our experience, the criminal inquiries usually follow the expose of scientific misconduct, not the other way around.

Fusco’s work is highly cited, with some 50 papers cited at least 100 times, according to Thomson Scientific’s Web of Knowledge.

According to the institute’s website: Continue reading Italian cancer specialist facing criminal investigation for misconduct

Aoki notches fourth retraction for image problems

We have a fourth retraction in the Journal of Biochemistry for Naohito Aoki, a Japanese researcher and former postdoc in a German lab, whose images have been called into question but whose retraction notices were scant. In this case, however, the journal, while not exactly overbrimming with information about the article, at least gives us some sense of what’s going on.

Aoki worked in the lab of Axel Ullrich, of the Max Planck Institute of Biochemistry, and appeared on two retracted articles in the Journal of Biological Chemistry (JBC) with his mentor, along with a third with a co-author from Japan, Tsukasa Matsuda. Although those notices don’t say anything about the reason for the retractions — this was before the JBC started providing such information — Ulrich told us that Aoki had been manipulating images.

A Cancer Cell mega-correction for highly cited researcher who retracted paper earlier this year

MIT’s Robert Weinberg, a leading cancer researcher who retracted a Cancer Cell paper earlier this year for “inappropriate presentation” of figures, has corrected a different paper in the same journal.

Here’s the correction for “Species- and Cell Type-Specific Requirements for Cellular Transformation:”

We were apprised recently of errors made in the assembly of Figures 2B, 3A, 4A, 4B, and 5G, resulting in the incorporation of incorrect representative images in these figures. These errors occurred during the electronic assembly and have no bearing on the conclusions of the study. The corrected figures are shown below. The authors apologize for any possible confusion this might have caused.

Here’s the original Figure 2 and caption, followed by the new version (read all the way to the end of the post for more details on how this came to light): Continue reading A Cancer Cell mega-correction for highly cited researcher who retracted paper earlier this year

Image highjinx lead to retraction of hot pepper paper

You might be forgiven for thinking that the editors were describing a bad relationship rather than a paper gone wrong, the journal of Plant and Cell Physiology is retracting a 2004 article by Korean researchers who “manipulated and repeatedly used” micrographs.

The article, “Ornithine Decarboxylase Gene (CaODC1) is Specifically Induced during TMV-mediated but Salicylate-independent Resistant Response in Hot Pepper,” which appeared a s a short communication in the journal, came from the lab of Kyung-Hee Paek at Korea University.

According to the retraction notice: Continue reading Image highjinx lead to retraction of hot pepper paper
