JBC retraction on neuron development marks second for two biologists

JBCTwo biologists have retracted a second paper on the development of neurons, but that’s about all we know.

The 2007 paper from the Journal of Biological Chemistry, “The Interaction of mPar3 with the Ubiquitin Ligase Smurf2 Is Required for the Establishment of Neuronal Polarity,” concerns the role of a protein, mPar3, in neuron development. It has been cited 29 times, according to Thomson Scientific’s Web of Knowledge.

We don’t know why this one was retracted, because JBC (as usual) offered no explanation in its retraction note:

JCI issues mega-correction for multiple myeloma paper

125-7-coverThe Journal of Clinical Investigation has issued a lengthy correction to a paper about the role of the immune system in the progression and treatment response of multiple myeloma.

The correction changes details from the name of an author to figure legends, and adds entire supplemental figures.

Shortly after the paper’s publication on April 20th, commenters on PubPeer pointed out duplications in multiple figure panels.

Last month, the journal issued an extensive correction note for “Immunosurveillance and therapy of multiple myeloma are CD226 dependent,” which, in part, tries to explain the multiple duplications.

It starts out noting a typo:

Two crystallography papers break apart for “trivial errors,” says author

ACBiophysicists in India have retracted two crystallography papers describing protein binding sites following “concerns,” according to one retraction note.

The last author on both papers, however, told us he believed the retractions were the result of “trivial errors.” Although one journal praised him in its retraction note for his “positive engagement,” he said the process left him feeling “disgusted.”

One paper, “Structural Studies on Molecular Interactions between Camel Peptidoglycan Recognition Protein, CPGRP-S, and Peptidoglycan Moieties N-Acetylglucosamine and N-Acetylmuramic Acid,” was withdrawn from the Journal of Biological Chemistry in August 2014.

The second, “Mode of binding of the antithyroid drug propylthiouracil to mammalian haem peroxidases,” was retracted from Acta Crystallographica Section F this month. Here’s the retraction notice: Continue reading Two crystallography papers break apart for “trivial errors,” says author

Cancer Research retraction is fifth for Robert Weinberg; fourth for his former student

13.coverAnother domino has fallen in a chain of retractions for Robert Weinberg, the man who discovered the first tumor-causing gene in humans, along with the first tumor suppressor gene: Cancer Research just retracted a paper of his on some of the molecular steps to metastasis.

The paper, “Concurrent Suppression of Integrin α5, Radixin, and RhoA Phenocopies the Effects of miR-31 on Metastasis,” has been cited 70 times, according to Thomson Scientific’s Web of Knowledge. As we have noted before, Weinberg’s papers are frequently highly cited. His bio at the Whitehead Institute bills him as “a pioneer in cancer research.”

Four of Weinberg’s retracted papers — including this latest — share a first author: Scott Valastyan, once a very promising grad student in Weinberg’s lab. 

This retraction, like Valastyan’s others, is linked to his retracted 2009 Cell paper. (That paper was cited 482 times, and there’s even a video from the Cell press office to go with it). Continue reading Cancer Research retraction is fifth for Robert Weinberg; fourth for his former student

Another author withdrawal from JBC earns another opaque notice

Journal of Biological Chemistry1The authors of a 2014 study on the biochemical changes that can encourage the progression of cancer have withdrawn the paper from the Journal of Biological Chemistry.

The post from the JBCwhich we’ve noted are rarely helpful – doesn’t provide any details or reason for the withdrawal. As usual, this is all we got:

Misidentified genetic sequence causes retraction of pathogen paper one month after publication

Genome Announcements

The author of an article mapping the genome of an infectious bacterium is pulling the paper because — well, it wasn’t the bacterium she thought it was.

Study author Celia Abolnik is retracting her paper in Genome Announcements because it didn’t actually map out the DNA of Mycoplasma meleagridis, a bacterium that typically infects turkeys but has recently been found in chickens.

The trouble was, the sequence for Mycoplasma meleagridis in the National Institute of Health’s DNA database, Genbank, was actually a different variety of bacteria — Mycoplasma gallinaceum, another scourge of poultry.

Here’s the notice for “Complete Genome Sequence of Mycoplasma meleagridis, a Possible Emerging Pathogen in Chickens:”

Corrections (and one EoC) propagate for distinguished plant biologist, Olivier Voinnet

There may be some deeply rooted issues in the work of high-profile plant biologist Olivier Voinnet, biology department research director at ETH in Zurich. Corrections have continued to pile up months after his work was hit with a barrage of criticism on PubPeer. We’ve tracked a total of seven corrections over the past five months (not including the April retraction of a 2004 paper in The Plant Cell). One of the corrected papers also received an Expression of Concern this week.

Collectively, the corrected papers have accumulated more than 1200 citations.

In January, Voinnet said he planned to correct multiple papers, after receiving “an anonymous email.”

One of the recent corrections we found is for a 2003 article in The Plant Journal, “An enhanced transient expression system in plants based on suppression of gene silencing by the p19 protein of tomato bushy stunt virus,” which details using proteins from a tomato virus to help alter gene expression. The study has been cited 862 times, according to Thomson Scientific’s Web of Knowledge. Here’s the correction notice, posted June 8:

“Values were outside expected ranges”: Toxicology paper spiked after audit

Toxicological PathologyResearchers at the National Institute of Environmental Health Sciences have retracted a 2014 article after a review unearthed unresolved problems with the study’s control material.

The retracted paper, “Effect of Temperature and Storage Time on Sorbitol Dehydrogenase Activity in Sprague-Dawley Rat Serum and Plasma,” looked to test the durability and stability of sorbitol dehydrogenase, an enzyme used to detect cancerous liver damage in rats.

Here’s the complete retraction notice from Toxicologic Pathology :

JBC cancer paper felled by duplication is one author’s second retraction this month

25.coverA 2002 paper in the Journal of Biological Chemistry on how lung cancer cells resist death has been retracted for duplicating figures from a 2001 paper.

The retracted paper, “Fibroblast growth factor-2 induces translational regulation of Bcl-XL and Bcl-2 via a MEK-dependent pathway: correlation with resistance to etoposide-induced apoptosis,” shares the first and last authors with the 2001 paper, in Oncogene, as well as two other co-authors.

Here’s JBC’s entire retraction note, a sub-genre with which we’ve become intimately familiar by now:

Lost your data? Blame an earthquake

coverJNC

A natural disaster is to blame for a retraction about lethal brain tumors. At least, that’s where the authors say the problem started: with a 2010 earthquake that caused a loss of “substantial data.”

The paper, “Superoxide-dependent uptake of vitamin C in human glioma cells,” looks at how the cells of lethal brain tumors interact with the vitamin commonly used to reduce side effects of therapies.

Post earthquake, someone digitally filled in a western blot analysis of proteins from a cell line and rat brains, as a “temporary solution.” And then the temporary solution made its way into the Journal of Neurochemistry.

Here’s the retraction note from the journal, including an image of the sneaky western blot:
