Northwestern researcher has four more papers retracted, making five

Yashpal Kanwar

A pathologist in Chicago has lost five papers for image manipulation and other problems. 

The first retraction for Yashpal Kanwar, of the Feinberg School of Medicine at Northwestern University, appeared in 2013, for a review article published earlier that year in the American Journal of Physiology Renal Physiology. According to the notice

UCLA group has three papers retracted

The Journal of Biological Chemistry has retracted three papers by a group from the University of California, Los Angeles, citing problems with the figures. 

Two of the papers, published in 2002, 2004 and 2009, have the same last author, Mark H. Doolittle, who is the first author of the most recent article. Doolittle, who appears to be a highly talented woodworker, has left UCLA and did not respond to a request for comment. 

The retraction notice for the 2002 paper, “Maturation of lipoprotein lipase in the endoplasmic reticulum: Concurrent formation of functional dimers and inactive aggregates,” states:

Georgia State researcher has two papers retracted, eight flagged. He’s not happy about it.

The Journal of Biological Chemistry has retracted two papers by a Georgia State University researcher, as well as flagged eight more with expressions of concern, a move the scientist called “unfair and unjustified.”

Ming-Hui Zou, the common author on all ten papers — as well as on two more that have been corrected by the same journal — is, according to Georgia State,

an internationally recognized researcher in molecular and translational medicine and a Georgia Research Alliance Eminent Scholar in Molecular Medicine and associate vice president for research at Georgia State University…

Zou was at the University of Oklahoma when the papers in question were published. He moved to Georgia State in 2015.

Here’s the retraction notice for “Reactive nitrogen species is required for the activation of the AMP-activated protein kinase by statin in vivo,” published in 2008 Zou as the last author:

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.

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.

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

Researcher in South Korea racks up three retractions and at least 10 corrections

Joohun Ha

A professor at Kyung-Hee University in Seoul, South Korea, has retracted three articles and had at least ten corrected, all for image manipulation, duplication, or errors.

Joohun Ha’s three retractions all appeared in the Journal of Biological Chemistry (JBC). One of the papers, “AMP-activated protein kinase activity is critical for hypoxia-inducible factor-1 transcriptional activity and its target gene expression under hypoxic conditions in DU145 cells,” first published in 2003, has been cited 186 times, according to Clarivate Analytics’ Web of Science. Here’s the retraction notice: Continue reading Researcher in South Korea racks up three retractions and at least 10 corrections

University of Kentucky cancer toxicologist retracts three papers for image duplication

Xianglin Shi

A researcher at the University of Kentucky who studies the cancer risks of toxic chemicals has retracted three papers.

All of the retraction notices, which appear in the Journal of Biological Chemistry, refer to some kind of image duplication. The papers were originally published between 2014 and 2017, with the 2014 paper cited 39 times, according to Clarivate Analytics’ Web of Science.

Cancer researcher at OSU up to nine retractions

Samson Jacob

A cancer researcher and emeritus professor at The Ohio State University has retracted four more papers, bringing his total to nine from a single journal.

The four retractions of work by Samson Jacob appear in the Journal of Biological Chemistry, from which Jacob retracted five papers in March. The original papers — one of which has been cited more than 250 times — date back to 2002.

OSU declined to say whether Jacob’s work was under investigation: Continue reading Cancer researcher at OSU up to nine retractions
