Fazlul Sarkar, who sued PubPeer commenters for criticizing his work, has logged two more retractions, bringing his total to seven.

The two retractions appear in the Journal of Cellular Physiology, and follow five others released last week by another Wiley journal, Journal of Cellular Biochemistry. All notices mention an investigation at Wayne State University, where Sarkar is on the faculty.

Here’s the notice for “Activated K-Ras and INK4a/Arf Deficiency Promote Aggressiveness of Pancreatic Cancer by Induction of EMT Consistent With Cancer Stem Cell Phenotype:” Continue reading Seventh retraction appears for cancer researcher who sued PubPeer commenters

An investigation at Wayne State University has prompted five retractions for a scientist who is suing PubPeer commenters after they criticized his work on the site.

The investigation into Fazlul Sarkar and his co-authors found that the papers contain images that were “inappropriately manipulated” or “inappropriately re-used and re-labeled.” All five retraction notices are from the Journal of Cellular Biochemistry.

Here’s the retraction notice for “Concurrent inhibition of NF-κB, cyclooxygenase-2, and epidermal growth factor receptor leads to greater anti-tumor activity in pancreatic cancer:

Figures questioned online were manipulated, says Malaysia investigation

The image that excited twitter: Figure 6 from the Scientific Reports paper
The image that set Twitter abuzz: Figure 6 from the Scientific Reports paper, in which every cell in each stage of cell death appeared to be an exact copy.

Many figures in four papers by a research team in Malaysia contain duplication or manipulation, a university committee has found, calling for multiple retractions.

We learned about issues with three of the papers, including one in Scientific Reports, earlier this week when they were the talk of Twitter. As journals issued expressions of concern, and an expert wondered how the papers passed peer review at all, the first author, a researcher at the University of Malaya (UM), denied allegations of duplication.

UM was alerted to allegations of misconduct in the Scientific Reports paper last Saturday, and according to a statement published today:

Fake email for corresponding author forces neuro journal to retract paper

Cellular and Molecular NeurobiologyA chair of a neurobiology department in China has requested the retraction of a paper on which he was unwittingly listed as the lead and corresponding author.

How could a corresponding author — you know, the person with whom the journal corresponds about the paper — be added without their consent? It seems that a fraudulent email account was involved in this case. The address listed for Cheng He, a researcher at the Second Military Medical University in Shanghai, didn’t belong to him, said a spokesperson for Springer.

According to the retraction notice for “Identification of the Interaction Between the Human Homologue of the Arabidopsis COP9 Signalosome Subunit 7a and Olig1:”

Third party company botched student’s doctoral work, says biologist

Cellular Physiology and BiochemistryA PhD student who was supposed to complete part of an experiment passed the job on to a third party company, which in turn provided figures that were plagiarized and fabricated. That’s according to the corresponding author of the paper, which has now been retracted.

Hong Ren, affiliated with Xi’an Jiao Tong University in China, told us that he decided to delay the student’s graduation after he discovered that the student had passed off the work.

It’s not at all obvious that a third party was involved from the brief retraction notice for “EMT phenotype is induced by increased Src kinase activity via Src-mediated caspase-8 phosphorylation:”

JAMA: No plan to retract article on fetal pain, despite outcry from anti-abortion activists

JAMAJAMA has announced it does not intend to retract a 2005 review article about fetal pain, despite requests from anti-abortion activists who claim it has been misused in debates about the procedure.

Earlier this month, JAMA told one anti-abortion critic that it would take a look at the paper, which suggested that fetuses can’t feel pain before the third trimester. Critics have argued that newer findings have shown pain sensation appears earlier in gestation, yet the 2005 data continue to be cited in the discussion around abortion. What’s more, critics have lamented that some of the authors failed to mention their ties to the abortion industry.

But in a letter sent yesterday to James Agresti, Howard Bauchner, Editor in Chief at JAMA and The JAMA Network, writes: Continue reading JAMA: No plan to retract article on fetal pain, despite outcry from anti-abortion activists

Images that raised eyebrows flagged by another journal; Malaysian gov’t investigates

Screen Shot 2016-06-15 at 9.17.15 AMMultiple investigations have been launched into allegations of blatant duplications by a research group in Malaysia.

Last week, users alleged on Twitter that three papers by the same team included pictures of cells that were copied and pasted. First author Nima Samie, affiliated with University of Malaya in Malaysia, denied the accusations — but both the Malaysian government and now two journals sees cause for further investigation.

Frontiers in Pharmacology published an expression of concern this morning:

Fraudster loses third attempt to remove 7-year debarment

court caseA U.S. judge has denied a virology researcher’s third attempt to overturn a seven-year debarment from receiving federal funds, following a 2010 decision by the U.S. Office of Research Integrity.

The ORI banned Scott Brodie for seven years after concluding he had committed 15 acts of misconduct at the University of Washington. The deception affected grant applications, published papers, manuscripts, and presentations. Since then, Brodie has tried multiple times to reverse the ruling in court.

In the latest decision, dated June 13, United States District Judge James E. Boasberg writes: Continue reading Fraudster loses third attempt to remove 7-year debarment

Misidentified cell line fells cancer paper

Screen Shot 2016-04-15 at 2.52.06 PMResearchers have retracted a paper about a new molecular target for cancer after realizing they had mistaken the identity of their cell line.

It’s all too easy to mix up cell lines, so we see plenty of retractions for that reason — and, according to an expert in the area, many more cases lurk uncorrected in the literature.

The retraction notice for “Knockdown of tumor protein D52-like 2 induces cell growth inhibition and apoptosis in oral squamous cell carcinoma” in Cell Biology International explains the authors’ perspective on this case:

Columbia investigation reveals researcher faked data — and a degree

InnateImmunityA researcher faked data and a masters degree, according to an investigation by Columbia University.

He’s also earned his fourth retraction. The new notice, along with one we’ve uncovered from 2014, provide some information on the extent of the deception of Robert Frumento, who left Columbia a decade ago, around the time that the now-retracted papers were published.

Here’s the new retraction notice:
