Fourth retraction appears for cancer researcher Anil Jaiswal

with 6 comments

cancer research 1113The hits keep coming for University of Maryland researcher Anil Jaiswal.

The latest retraction for the cell biologist is in Cancer Research, for a 2007 paper about ways in which the cell tries to protect the tumor suppressor p53. Like the first Jaiswal retraction we covered, the latest notice specifically taps figure duplication as the cause of death, “as a result of an error.” The other two retractions gave no explanation for the withdrawal.

The retraction countdown: How quickly do journals pull papers?

with 2 comments

After Tina Wenz was found guilty of scientific misconduct, how long did it take for journals to retract the problematic papers?  The answer: Between three and nine months.

In September 2016, the University of Cologne found that Wenz had committed scientific misconduct in six papers and requested they all be retracted. From that point on, the retraction clock was ticking.

We’ve explored how long it takes a journal to act over the years, and we’ve found that the time between identifying a problem to retracting the paper can vary — and sometimes last years.

In Wenz’s case, one of the papers—published in Cell Metabolism in 2009—had already been retracted in 2015. Three of the remaining five were retracted in December 2016—a 2008 paper in Cell Metabolism, a 2009 paper in Proceedings of the National Academy of Sciences (PNAS), and a 2009 paper in the Journal of Applied Physiology.

In January 2017, the journal IUBMB Life pulled a 2014 paper flagged in the investigation. And just over nine months after Wenz was found guilty of misconduct, the last paper—published in 2013 in Mitochondrion—has been retracted.

The most recent notice states that the University of Cologne requested the retractions, after determining that the data had been “inappropriately manipulated.”

Here’s the retraction notice in Mitochondrion:

A university asked for numerous retractions. Eight months later, three journals have done nothing.

When journals learn papers are problematic, how long does it take them to act?

We recently had a chance to find out as part of our continuing coverage of the case of Anil Jaiswal at the University of Maryland, who’s retracted 15 papers (including two new ones we recently identified), and has transitioned out of cancer research. Here’s what happened.

As part of a public records request related to the investigation, we received letters that the University of Maryland sent to 11 journals regarding 26 “compromised” papers co-authored by Jaiswal, four of which had been retracted by the time of the letter. The letters were dated between August and September 2016 (and one in February) — although, in some cases, the journals told us they received the letter later. Since that date, three journals have retracted nine papers and corrected another, waiting between four and six months to take action. One journal published an editorial note of concern within approximately two months after the university letter.

And six journals have not taken any public action.

Cancer biologist stops research as his retraction count rises to 13

with 16 comments

Anil Jaiswal

A cancer biologist based at the University of Maryland is transitioning out of research, as a journal has retracted three more of his papers.

Anil Jaiswal has now lost 13 papers, including, as we reported on February 6, six retractions issued earlier this month.

The Baltimore Sun reported this week that Jaiswal would no longer be conducting research at the University of Maryland School of Medicine, which we confirmed from a spokesperson:

Cancer researcher logs 6 retractions, bringing total to 10

with 24 comments

Anil Jaiswal

A journal has retracted six papers by a cancer researcher at the University of Maryland in Baltimore, bringing his total to 10.

The retractions cite an investigation by the university, and detail problems ranging from duplicated images, to tweaking an image to conceal particular bands, to including unreliable data.

Three of the papers had already been flagged by the journal with expressions of concern. The last author on all the papers is Anil Jaiswal, a professor in the pharmacology department. He has issued four previous retractions.

Bruce Jarrell, the Chief Academic and Research Officer and Senior Vice President at the University of Maryland, told us at least two more retractions are forthcoming:

Three expressions of concern added to cancer researcher’s notice list

with 12 comments

3.coverQuestions about data and conclusions in papers by a cancer researcher at the University of Maryland have led to three expressions of concern in the Journal of Biological Chemistry.

The notices follow four retractions — two for image duplications and two for unknown reasons — for Anil K. Jaiswal. The three papers under notice are all on mechanisms that regulate gene expression; PubPeer commenters have raised questions about some of the figures in the papers.

The expression of concern on all three papers reads, in full:

A pair of researchers at the University of Maryland have retracted a third paper.

University of Maryland researchers notch second retraction

with 5 comments

jbc 42514Two researchers at the University of Maryland who retracted a paper earlier this year for a duplicated figure have withdrawn another, this time for unknown reasons.

The Journal of Biological Chemistry (JBC) paper has been cited 16 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice, for “Hsp90 Interaction with INrf2(Keap1) Mediates Stress-induced Nrf2 Activation,” which is unfortunately a return to the JBC’s opacity: Read the rest of this entry »

Figure duplication kills cell death paper

cdd_cimageA pair of researchers at the University of Maryland have retracted a paper in Cell Death & Differentiation after it became clear that one of the figures had been duplicated from an earlier paper.

Here’s the notice, dated December 13, 2013, for “INrf2 (Keap1) targets Bcl-2 degradation and controls cellular apoptosis,” by Suryakant Niture and Anil Jaiswal: Read the rest of this entry »
