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:

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.

Here’s the notice: Read the rest of this entry »

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

Here’s the unhelpful Journal of Biological Chemistry notice for “Inhibitor of Nrf2 (INrf2 or Keap1) protein degrades Bcl-xL via phosphoglycerate mutase 5 and controls cellular apoptosis,” by Suryakant Niture and Anil Jaiswal: Read the rest of this entry »

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 »
