Serial fakery: Researcher found to have committed misconduct at Harvard and Oxford

harvardA former Harvard postdoc who was found guilty of faking data at Oxford as a student did the same thing at Harvard, according to the Office of Research Integrity (ORI).

We first wrote about Helen Freeman in February, when we covered a retraction in Cell Metabolism that said the UK’s Medical Research Council had found that she committed misconduct while working as a student at Oxford. Today, a Federal Register notice from the ORI reports that Freeman faked images in a manuscript submitted to Nature while she was working on federally funded grants at Harvard Medical School and Beth Israel Deaconess Medical Center.

From the ORI’s report: Continue reading Serial fakery: Researcher found to have committed misconduct at Harvard and Oxford

Diabetes researcher who says he will no longer publish now up to five retractions

Cory Toth, the University of Calgary diabetes researcher who told us last month he would stop publishing in science following a string of inappropriate manipulations, has retracted another paper.

Here’s the notice in Brain for “Intranasal insulin prevents cognitive decline, cerebral atrophy and white matter changes in murine type I diabetic encephalopathy:” Continue reading Diabetes researcher who says he will no longer publish now up to five retractions

Forged authorship sinks melanoma paper

ijbcbThe International Journal of Biochemistry & Cell Biology has retracted a 2013 paper by a group from China after learning that only the first author knew about the article.

The paper was titled “Construction of circular miRNA sponges targeting miR-21 or miR-221 and demonstration of their excellent anticancer effects on malignant melanoma cells,” and it was led by Yuchen Liu. Liu’s affiliations include the Institute of Dermatology and Department of Dermatology at No. 1 Hospital, part of Anhui Medical University, and the State Key Laboratory Incubation Base of Dermatology for the Ministry of National Science and Technology.

Here’s the retraction notice:

Sampling error, flawed analysis, and miscalculation trigger Molecular Cell retraction

molecular cell 14Guest post by Jean Hazel Mendoza

A group of researchers from France has retracted a 2013 paper from Molecular Cell after realizing that their analyses of microscopy images were flawed.

Here’s the notice for “RecA-Promoted, RecFOR-Independent Progressive Disassembly of Replisomes Stalled by Helicase Inactivation:” Continue reading Sampling error, flawed analysis, and miscalculation trigger Molecular Cell retraction

Shigeaki Kato, who resigned from the University of Tokyo in 2012 after being found to have inappropriately manipulated dozens of images, has two more retractions, both in Molecular Cell.

Here’s the notice for 2002’s “Nuclear Receptor Function Requires a TFTC-Type Histone Acetyl Transferase Complex:” Continue reading Shigeaki Kato up to 25 retractions

Retraction appears for former federal contractor who faked data

cebpIn December, we reported on the case of Timothy Sheehy, a former government contractor who was found to have faked results. ORI found that Sheehy

fabricated the quantitative and qualitative data for RNA and DNA purportedly extracted from 900 formalin-fixed, paraffin-embedded (FFPE) colorectal tissue samples presented in Table 1 of the CEBP paper and falsely reported successful methodology to simultaneously recover nucleic acids from FFPE tissue specimens, when neither the extractions nor analyses of the FFPE samples were done. Thus, the main conclusions of the CEBP paper are based on fabricated data and are false.

Sheehy agreed to ask that one of his papers be retracted. The retraction notice has appeared: Continue reading Retraction appears for former federal contractor who faked data

Retractions 3 and 4 appear for researcher facing criminal probe; OSU co-author won’t face inquiry

University of Maryland researchers notch second retraction

jbc 42514Two researchers at the University of Maryland who retracted a paper earlier this year for a duplicated figure have withdrawn another, this time for unknown reasons.

The Journal of Biological Chemistry (JBC) paper has been cited 16 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice, for “Hsp90 Interaction with INrf2(Keap1) Mediates Stress-induced Nrf2 Activation,” which is unfortunately a return to the JBC’s opacity: Continue reading University of Maryland researchers notch second retraction

Former Mount Sinai postdoc faked gene therapy data: ORI

ori logoA former postdoc at the Mount Sinai School of Medicine in New York faked data in four published papers, one submitted manuscript, and four NIH grant applications, according to new findings by the Office of Research Integrity.

We reported on six retractions from Savio Woo’s Mount Sinai lab in 2010, from the Proceedings of the National Academy of Sciences (PNAS), the Journal of the National Cancer Institute, and two each from Human Gene Therapy and Molecular Therapy. The PNAS paper, as we noted then:

claimed to have discovered a possible cure for phenylketonuria, or PKU, in mice—a finding that was cited more than 30 times and trumpeted in the media.

At the time, Mount Sinai said that two of the lab’s postdocs had been dismissed for misconduct. Now, more than three and a half years later, the ORI reports that a former postdoc in that lab, Li Chen: Continue reading Former Mount Sinai postdoc faked gene therapy data: ORI

Brutal honesty: Author takes to PubPeer to announce retraction — and tells us she’ll lose PhD, professorship

Over the past week, there have been a number of comments on PubPeer — a site of which we’re big fans — about a 2007 paper in Oncogene.

The comments suggested that the figures in the paper had problems. Some bands seemed to be duplicated, and one of the images looked very much like that of another paper.

Then, today, first author Eriko Suzuki left this comment: Continue reading Brutal honesty: Author takes to PubPeer to announce retraction — and tells us she’ll lose PhD, professorship
