Cancer researcher contributed “false data” to 11 studies

ori-logoA former cancer researcher has falsified data in 11 studies, according to the results of a investigation scheduled to be published in the Federal Register tomorrow.

The Office of Research Integrity’s findings are based on an inquiry at Virginia Commonwealth University, where Girija Dasmahapatra worked until July of this year, investigating possible therapies for cancer. The misconduct affected research funded by three grants from the National Institutes of Health. Steven Grant, a researcher at VCU, is the principal investigator on the grants, each of which total over $2 million in funding. All of the 11 affected papers will be corrected or retracted, according to the ORI notice.

Two of the papers containing “falsified and/or fabricated” data — a study on an experimental combination of drugs for blood cancer and one on chemotherapies for rare forms of lymphoma  — were covered in press releases by VCU.

According to the notice in the Federal Register:

Diederik Stapel now has 58 retractions

stapel_npcSocial psychologist Diederik Stapel has notched his 58th retraction, after admitting he fabricated data in yet another article.

He’s holding onto his 4th place spot on our leaderboard.

This latest retraction is for “Correction or comparison? The effects of prime awareness on social judgments,” published in the European Journal of Social Psychology. As usual for Stapel, this paper has been retracted because he fabricated data.

Here’s the note:

Voinnet retracts highly cited paper, bringing his total to 7

coverOlivier Voinnet, a well-known plant scientist at the ETH in Zurich, has notched his 7th retraction for a highly cited paper. The 2003 paper was pulled when “additional image manipulations” came to light after The Plant Journal issued a correction earlier this year.

The retraction follows an investigation into — and then retraction of — several other papers co-authored by Voinnet. The authors originally corrected the paper after they learned one image had been duplicated, and repeating the experiment found the “same interpretation and conclusions” held true. But when the corresponding author learned of additional “data manipulation,” they decided to retract the paper altogether.

Here’s the retraction notice for “An enhanced transient expression system in plants based on suppression of gene silencing by the p19 protein of tomato bushy stunt virus:”

MD Anderson researcher Aggarwal up to six corrections

cover (2)A highly cited cancer researcher at MD Anderson has notched three major corrections, all associated with problems in figures. One note cites “human error” as the cause.

Bharat Aggarwal is the last author on all three papers. He is now up to six corrections, two unexplained withdrawals, and two Expressions of Concern. He’s also threatened to sue us in the past, and has told us that his institution has been looking into his work.

Only one note specifies that the correction does not affect the paper’s conclusions.

First up: “Inhibition of growth and survival of human head and neck squamous cell carcinoma cells by curcumin via modulation of nuclear factor-κB signaling,” published in the International Journal of Cancer and cited 168 times, according to Thomson Scientific’s Web of Knowledge. The issues span two figures, according to the erratum note:

How does gender influence publishing? A window into one journal

fec_29_10 100Male and female reviewers may rate papers the same way, regardless of whether the authors are male or female — but women are more likely to get the chance to review papers (and get their own papers reviewed) if other women are involved, according to studies of the review process at Functional Ecology.

In their comprehensive study of manuscripts put through the peer review process at the journal from January 2004 through June 2014, the authors found that the average review scores of manuscripts was roughly the same regardless of whether the reviewer — or editor — was male or female.

The authors also scanned papers submitted to the journal between 2010 and 2014 to look at the impact of gender among authors, and also found papers with female authors receive equivalent scores to papers by men: Continue reading How does gender influence publishing? A window into one journal

“Most responsible course of action is to retract:” Duplicated images fell prostate cancer paper

International Journal of CancerA study on the cellular interactions underlying prostate cancer has been retracted after a whistleblower pointed out duplicated images in one of the paper’s figures that were “erroneously presented as unique.”

The International Journal of Cancer posted the notice in June. The authors backed the paper’s conclusions but agreed, “the most responsible course of action is to retract.”

The notice reads:

More retractions, errata discovered for nursing researcher

Journal of Clinical Nursing

Since our recent coverage about a university investigation that led to multiple retractions for nursing researcher Moon-fai Chan, we’ve been alerted to a few more retractions and errata. His total is now at six retractions and four errata.

Some of our finds were published this year, and some are a few years old. Most are due to duplication; one is due to “use of a dataset without ethical approval.” Chan — now the Associate Master and Chief of Students at the University of Macau — is the first author on all but one of the papers.

We’ll start with the most recent errata. Three of Chan’s articles in the Journal of Clinical Nursing have errata notes published online in July of this year, all noting that the authors used elements of some of Chan’s other articles. Here’s the erratum note for “Exploring risk factors for depression among older men residing in Macau:”

Cholesterol paper duplicated; “The authors believed that they had taken the necessary steps to withdraw.”

Biological Reviews

A review journal is pulling a 2013 article about advances in researchers’ understanding of cholesterol after seeing the same article in another journal.

Although the retracted paper appeared first — online in Biological Reviews in February, 2013 — the journal decided to retract it after learning the authors had initially submitted it elsewhere. The first submission was eventually published (with the exception of one author) in 2014 in Frontiers in Bioscience

The authors say they “believed that they had taken the necessary steps to withdraw their paper from Frontiers in Bioscience before they submitted to Biological Reviews in June 2012.” Here’s more from the retraction notice:

“Dual submission issues” retract both copies of ovarian cancer paper

Journal of Cellular PhysiologyAuthors of a study on a potential biomarker for ovarian cancer have been hit with two retractions after the results were published twice.

We don’t usually see both copies of a duplicated paper retracted, but this is a somewhat unusual case. In November 2011, a group of authors submitted the paper to Gynecologic OncologyBut two months’ prior, the first author had decided to also submit the paper to the Journal of Cellular Physiology, without listing three of the other researchers, including the primary author on the paper. It was published by the Journal of Cellular Physiology first, then by Gynecologic Oncology, both in July, 2012. 

Jie Chen, first author on both articles, “takes full responsibility for the dual submission” and “other co-authors should be exempted from all responsibilities,” as the retraction notice from Gynecologic Oncology explains.

P53 researcher submitted paper “without permission from his co-authors”

Screen Shot 2015-10-20 at 1.23.37 PM

One issue that we see pretty regularly is a paper submitted by one author without the permission of the others.

That’s what’s happened with “p53-induced Rap2B positively regulates migration in cells exposed to glucose deprivation,” published in July by Molecular Carcinogenesis. The paper looks at a protein called p53, well-known to regulate cell growth and, when mutated, cause cancer.

Here’s the pretty straightforward retraction note:
