Lab squabble leads to retracted correction over authorship in British Journal of Haematology

Here’s a he said-he said that left one author with a publication, then nothing, and us scratching our heads.

In March 2010, the British Journal of Haematology issued a rather straightforward correction regarding a 2007 article by a group of researchers from Kansas Kansas City, Missouri.

The glitch? The manuscript evidently left out an author:

In Iyamu et al (2007), the list of authors was incorrectly published and should have read:

Efemwonkiekie W. Iyamu, Syed Jamal, Chiazotam Ekekezie and Gerald M. Woods

Or maybe not. The journal is now retracting the correction: Continue reading Lab squabble leads to retracted correction over authorship in British Journal of Haematology

New retraction sheds light on Medical College of Georgia vascular biology case

In late January, we wrote a post about a retraction in the journal Molecular Endocrinology involving work from the lab of Stephen M. Black, of the Vascular Biology Center at at the Medical College of Georgia.

At the time, we didn’t know much. The notice was pretty thin sauce, although it hinted at “significant concerns with the data,” and we were led to believe that the first author of the article, Neetu Sud, a post-doc in Black’s lab, might have been implicated in those concerns. Because Black’s lab was working with substantial amounts of NIH funding, the prospect of an investigation by the Office of Research Integrity seemed likely.

Now we have a little more to go on. The American Journal of Physiology: Lung Cellular and Molecular Physiology has retracted another article by Sud and Black. The paper, titled “Protein kinase Cδ regulates endothelial nitric oxide synthase expression via Akt activation and nitric oxide generation,” appeared in 2008 and included a third author, Stephen Wedgwood, of Northwestern University. It has been cited 10 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice: Continue reading New retraction sheds light on Medical College of Georgia vascular biology case

Second retraction arrives in Alirio Melendez case

Alirio Melendez, whose former employer, the National University of Singapore, is investigating about 70 of his papers, has retracted a second study. Here’s the notice for the 2010 Journal of Molecular Cell Biology paper, “Sphingosine-1-phosphate mediates proliferation maintaining the multipotency of human Adult Bone Marrow and Adipose Tissue-derived Stem Cells:” Continue reading Second retraction arrives in Alirio Melendez case

Following investigation, U Ottawa lab retracting four papers in the Journal of Biological Chemistry

A University of Ottawa lab has been forced to retract four papers from the Journal of Biological Chemistry (JBC) after an investigation of image manipulation.

According to an email from a university official obtained by Retraction Watch, a university investigative committee had “found substance to the allegations,” although it claimed it could not disclose details “due to their confidentiality.” The university requested that the JBC withdraw a November 2005 paper, and left it to the journal to “determine whether the other articles should also be withdrawn or if they can be corrected. ” And they took the issue to the agency that funded the work: Continue reading Following investigation, U Ottawa lab retracting four papers in the Journal of Biological Chemistry

Zhiguo Wang retractions appear in the Journal of Cellular Physiology

Last month, we reported that the last three of six promised retractions by Zhiguo Wang, who was a researcher at the Montreal Heart Institute until the results of an Institute investigation forced him to resign in early September — would be in the Journal of Cellular Physiology. They’ve now appeared.

Here are the three notices, which are far more informative than the Journal of Biological Chemistry was — and which make it clear Wang acted alone: Continue reading Zhiguo Wang retractions appear in the Journal of Cellular Physiology

Retraction comes as death of PI leads to lost records

The Journal of Experimental Medicine has retracted a 2011 article after the principal investigator’s home institution suggested that the PI might have manipulated his data. Complicating matters, the PI in this case died two weeks after the paper appeared and his notes have gone missing — making an affirmative declaration of fraud or honest error difficult.

Here’s the notice: Continue reading Retraction comes as death of PI leads to lost records

A retraction as a group’s papers on smoking and weight loss are too close for comfort

The American Journal of Physiology Endocrinology and Metabolism is retracting a 2009 article by Japanese researchers who appeared to be so fond of their data they published them thrice.

The paper, “Dual suppression of adipogenesis by cigarette smoke through activation of the aryl hydrocarbon receptor and induction of endoplasmic reticulum stress,” by Masanori Kitamura and colleagues, looked at the biochemical mechanism by which cigarette smokers seem to be able to keep weight off. It has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

But according to the retraction notice: Continue reading A retraction as a group’s papers on smoking and weight loss are too close for comfort

Retracted retraction leaves Genomics paper intact — but authors wonder if anyone will know

Last March, the journal Genomics retracted a paper, “Discovery of transcriptional regulators and signaling pathways in the developing pituitary gland by bioinformatic and genomic approaches,” for reasons that don’t really fit into a tight lede sentence. Let’s just say that at times the problems involved both questions of authorship and the validity of the research. More on all that in a moment.

Meanwhile, things change. Now the journal, an Elsevier title, is un-retracting (that can’t be a real word, can it?) the retraction. You’d think that would please the authors, and it does to an extent. But they also wonder, legitimately, whether the original retraction will refuse to relinquish its grip on the resurrected article and consign it to database oblivion.

First, some background. Continue reading Retracted retraction leaves Genomics paper intact — but authors wonder if anyone will know

Remaining Zhiguo Wang retractions will be in the Journal of Cellular Physiology

We’ve been following the case of Zhiguo Wang, the former Montreal Heart Institute researcher who was forced to resign his post in early September following an investigation into his work. At the time of that announcement, two retractions of the Wang group’s papers — which we had reported on in August — had appeared. The Institute said they had requested three more.

We figured that meant a total of five, although the Institute wouldn’t say which they were. So when we found out about a third retraction, in the Journal of Cell Science, we said it was the first of the remaining three.

We were wrong. Continue reading Remaining Zhiguo Wang retractions will be in the Journal of Cellular Physiology

ExpungedBob? Algae journal pulls phytoplankton paper with unwitting co-author

While looking at a recent retraction notice in the Journal of Phycology, the one of us with small children at home couldn’t help but imagine a conversation between cartoon character SpongeBob and his nemesis, Plankton:

SpongeBob: You used me … for land development! That wasn’t nice.

Sheldon J. Plankton: Haven’t you figured it out, SpongeBob? Nice guys finish last. Only aggressive people conquer the world. Ha ha ha ha!

SpongeBob: Well … what about aggressively nice people?

Who knew the world of phytoplankton could be so cutthroat? (Spoiler alert: we did.)

Consider: The Journal of Phycology — phycology is the study of algae and related organisms — is retracting a paper after learning that one of the three co-authors, well, wasn’t. Cyanobacteria may be the oldest known life form on earth, but the hyper-ambitious aren’t far behind.
