Fudged figures sink breast cancer paper

oncogeneA prestigious cancer journal has pulled an article over “concerns” regarding some of the figures, which PubPeer commenters had tagged as suspect.

A few weeks after the paper was published on June 9, comments on PubPeer began accumulating. Commenters called out both potentially manipulated and repeated images. The exact timeline is not clear, because Oncogene does not list a date on the retraction notice, but by August 29 the paper had been retracted.

Here’s the notice for “IL-6 secreted by cancer-associated fibroblasts induces tamoxifen resistance in luminal breast cancer,” by researchers at Shanghai Jiaotong University School of Medicine and Ruijin Hospital, both in Shanghai, China, and the University of Michigan: Continue reading Fudged figures sink breast cancer paper

87% of bugs resistant to antibiotics? Not so fast, as staph paper yanked after staff mistake

What could have been a truly scary study about drug resistant staph infections in hospitals has been retracted due to a lab error.

6.coverResearchers at a community hospital in Pittsburgh claimed that the commonly quoted 3% rate of staph that is resistant to ceftriaxone and sensitive to methicillin was drastically understated. However, an “honest error in the interpretation of a key lab test” called the findings into question.

Here’s the abstract: Continue reading 87% of bugs resistant to antibiotics? Not so fast, as staph paper yanked after staff mistake

Structure fumble sinks second of author’s JACS papers

jacsat_v136i001.inddProof that organic chemistry is hard for everyone, not just pre-meds: A paper in the Journal of the American Chemical Society was retracted after the structures of compounds being studied were “misassigned.”

Another study by author Doo Ok Jang, also in JACS, was retracted in 2013 for the same reason; you can read our coverage here. Jang and Sang Yoon Kim published that one in 2008; the paper we’re talking about today was published in 2010 by Jang and Sung Jun Kim.

First author blamed for retraction in prestigious medical journal

jemcoverThe authors of a Journal of Experimental Medicine have retracted it, blaming the first author for data and figure manipulation.

The paper, “The requirements for natural Th17 cell development are distinct from those of conventional Th17 cells,” was initially published in September 2011 and has been cited 25 times, according to Thomson Scientific’s Web of Knowledge. First author Jiyeon Kim was an MD-PhD candidate at the University of Pennsylvania until this year, according to a LinkedIn profile.

Authors ask Science to retract Hayabusa asteroid paper

jaxa_logoThe Japan Aerospace Exploration Agency (JAXA) has requested that Science retract a 2006 paper about the makeup of asteroid Itokawa as observed from the spacecraft Hayabusa, the news section of Science reports.

Instead of calibrating their equipment on Earth, the scientists assumed they’d see both magnesium and silicon in the x-ray spectra, and used that assumption to assess the rest of the chemical composition of the asteroid.

The paper may be based on faulty assumptions, but the conclusions have been backed up by other published papers, according to the Science magazine report: Continue reading Authors ask Science to retract Hayabusa asteroid paper

Diabetes researcher Cory Toth now up to nine retractions

neuroscienceCory Toth is up to nine retractions.

The University of Calgary researcher who told us earlier this year that he “will not be publishing in the world of science in the future” has retracted two papers from Neuroscience.

Here’s the notice for “Local erythropoietin signaling enhances regeneration in peripheral axons:” Continue reading Diabetes researcher Cory Toth now up to nine retractions

Second retraction appears for former University of Florida ob-gyn subject to ORI probe

Chegini, via University of Florida

Nasser Chegini, an ob-gyn formerly on the faculty at the University of Florida who has been the subject of an Office of Research Integrity (ORI) inquiry for several years, has a second retraction.

Chegini is suspected of having used bogus data in some of his work — research backed in part by some $4 million in federal funding.

The new retraction involves a 2008 paper in Reproductive Sciences on which Chegini was senior author. Here’s the notice: Continue reading Second retraction appears for former University of Florida ob-gyn subject to ORI probe

Déjà vu: Double pub in the same issue earns a retraction

biomedchromAlways do a careful reading of your galleys, editors.

We imagine readers of Biomedical Chromatography’s special issue, “Reminiscences of Chang Kee Lim,” did some flipping back and forth when they found the same paper published twice.

Here’s the resulting notice for “Determination of 4-hydroxy-2-nonenal in serum by high-performance liquid chromatography with fluorescence detection after pre-column derivatization using 4-(N,N-dimethylaminosulfonyl)-7-hydrazino-2,1,3-benzoxadiazole”:  Continue reading Déjà vu: Double pub in the same issue earns a retraction

Journal takes down autism-vaccine paper pending investigation

translational neurodegenerationAn article purporting to find that black children are at substantially increased risk for autism after early exposure to the measles-mumps-rubella vaccine has been shelved.

Although we don’t know if the events are related, the move comes amid claims that a CDC whistleblower has accused health officials of suppressing information about the link.

Not surprisingly, the prospect that the CDC has been sitting on evidence of an autism-vaccine connection for more than a decade has inflamed the community of activists wrongly convinced that such a link exists.

The paper, “Measles-mumps-rubella vaccination timing and autism among young african american boys: a reanalysis of CDC data,” was written by Brian Hooker, an engineer-turned-biologist and an active member of that community. It was submitted in April, accepted on August 5, and published on August 8.

Translational Neurodegeneration, which published the article earlier this month, has now removed it and posted the following notice: Continue reading Journal takes down autism-vaccine paper pending investigation
