Biochemist in Spain retracts eight papers at once

Carlos López-Otín

A high-profile researcher at the Universidad de Oviedo in Spain has retracted eight papers from the Journal of Biological Chemistry for figure issues.

All of the papers were co-authored by Carlos López-Otín, who studies a group of enzymes that break down proteins, cancer genomics and aging, and whose lab web site boasts that

His works have been collected in more than 400 articles in international journals and have been cited to date more than 44.000 times, with an aggregate Hirsch index of h=100.

After university goes silent, diabetes journal retracts three papers

A group of researchers based in Italy has had three papers retracted for likely using the same images to represent different experimental conditions.

The retractions, in Diabetes, published by the American Diabetes Association (ADA), follow expressions of concern for the papers in early 2018 and the launch of an investigation by the authors’ institution into the work. The status of that investigation by Università degli Studi di Napoli Federico II, however, is unclear, as the university has stopped responding to the journal’s inquiries.

Here are the three now-retracted papers: Continue reading After university goes silent, diabetes journal retracts three papers

“We regret our delay:” PLOS ONE retracts two papers

PLOS ONE has retracted two papers for image problems, which we’ve learned were brought to the journal’s attention more than four years ago.

The first article came from a group of cancer researchers in China, and it turns out to have a bit more wrong than a few dodgy figures. The second also involved cancer research.

Asked about the delay, PLOS ONE told Retraction Watch: Continue reading “We regret our delay:” PLOS ONE retracts two papers

After more than a year of back and forth, an accounting journal retracts a paper on tax avoidance

A pair of business researchers in Pittsburgh has lost a controversial 2017 paper on how institutional stock holdings affect tax strategies amid concerns about the validity of the data.

The article, “Governance and taxes: evidence from regression discontinuity,” which appeared in The Accounting Review, was written by Andrew Bird and Stephen Karolyi, of Carnegie Mellon’s Tepper School of Business.

According to the abstract: Continue reading After more than a year of back and forth, an accounting journal retracts a paper on tax avoidance

An Australian university cleared a cancer researcher of misconduct. He’s now retracted six papers.

Levon Khachigian

The story of Levon Khachigian’s research is a long and winding tale.

One place to start would be in October 2009, when a paper co-authored by Khachigian — whose work at the University of New South Wales (UNSW) has been funded by millions of dollars in funding from the Australian government, and has led to clinical trials, although more on that later — was retracted from Biochemical and Biophysical Research Communications. The “corresponding author published the paper without the full consent or acknowledgement of all the researchers and would like to apologize for this error,” according to that notice. Continue reading An Australian university cleared a cancer researcher of misconduct. He’s now retracted six papers.

Group issues model retraction over antibody error

The authors of a 2013 paper on antibody production in patients with rheumatoid arthritis have retracted the work in what looks to us like a case study in how to handle operator error.

The paper, “Monoclonal IgG antibodies generated from joint-derived B cells of RA patients have a strong bias toward citrullinated autoantigen recognition,” was published in the Journal of Experimental Medicine by a group from the Karolinska Institutet (KI) in Sweden and elsewhere, and has been cited 128 times, according to Clarivate Analytics’ Web of Science. The last author, Vivianne Malmström, is a specialist in cellular immunology at the KI.

Here’s an excerpt from the lengthy notice: Continue reading Group issues model retraction over antibody error

Former UAB natural products researcher up to a dozen retractions

Santosh Katiyar

A researcher who studied natural products for cancer at the University of Alabama, Birmingham (UAB), had six papers retracted last month, bringing him to a total of 12.

Four of the recently retracted papers by Santosh Katiyar had appeared in PLOS ONE, and two had been published in Cancer Research. They have together been cited more than 250 times, according to Clarivate Analytics’ Web of Science, and are on subjects including compounds found in grape seeds and green tea.

Here’s an example, from PLOS ONE, for “Green Tea Catechins Reduce Invasive Potential of Human Melanoma Cells by Targeting COX-2, PGE2 Receptors and Epithelial-to-Mesenchymal Transition:” Continue reading Former UAB natural products researcher up to a dozen retractions

Japanese stem cell fraud leads to a new retraction

Last March, we reported on the retraction of a 2017 paper in Stem Cell Reports by Kohei Yamamizu and colleagues for widespread fabrication of figures. Turns out the problems were at least five years older than that.

Yamamizu had received a pink slip from his institution, the Center for iPS Cell Research and Application (CiRA), which had put the blame for the misconduct squarely on his shoulders. (The director of the institute, Nobel winner Shinya Yamanaka, also took some of the blame in a public statement in which he said he bore “a strong responsibility for not having prevented research misconduct at our institute.”)

Yamamizu has a new retraction, but this time’s a bit different. Here’s the notice for the paper, “Protein Kinase A Determines Timing of Early Differentiation through Epigenetic Regulation with G9,” which appeared in Cell Stem Cell in June 2012 (Yamanaka was not a co-author on either study).  Although the statement acknowledges the internal investigation, it doesn’t mention misconduct or name Yamamizu: Continue reading Japanese stem cell fraud leads to a new retraction

Journal retracts paper by controversial Australian journalist

Maryanne Demasi

The Journal of Biological Chemistry (JBC) has retracted a 2003 paper that resulted from the PhD thesis of Maryanne Demasi, an Australian journalist whose reporting on statins and the risks of cancer from cell phones has been a lightning rod.

The move, for what the journal says was attempts to reuse images to represent different experiments, follows an investigation by the University of Adelaide into allegations of image manipulation in Demasi’s thesis. In the investigation, Demasi

“Unusual aspects” of a figure — aka a cartoon of Trump’s face in baboon feces — disappear from a journal

“In the original version of this Article, there were unusual aspects to the ‘Extract fecal DNA’ illustration in figure 1. These features have been removed.”

With those 25 words, “one of the greatest scientific Easter eggs in a long time” or an image that was “highly unethical,” depending on your point of view, disappeared from a paper from Scientific Reports.
