A paper flagged in an Office of Research Integrity notice more than one year ago has finally been retracted. According to the notice, the paper includes images manipulated by author H. Rosie Xing, a former University of Chicago cancer researcher.
The main conclusions of the paper are affected by the ORI finding, according to the retraction note from Molecular Cancer Therapeutics. But otherwise, the note contains information that was available in the ORI finding, published in December 2014.
“Pharmacologic Inactivation of Kinase Suppressor of Ras1 Sensitizes Epidermal Growth Factor Receptor and Oncogenic Ras-Dependent Tumors to Ionizing Radiation Treatment” has been cited seven times, according to Thomson Scientific’s Web of Knowledge — twice since the ORI finding came out.
The retraction note explains which images were affected by the manipulation:
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:
The director of the Research Integrity & Compliance Review Office at Colorado State University (CSU) is the new head of the U.S. Office of Research Integrity, taking over a position that has been vacant for more than a year and a half.
The Office of Research Integrity report found that Maria C.P. Geraedts manipulated bar graphs in the papers to “produce the desired result.” Both have been retracted. Geraedts left academia in 2014, and is now a science writer.
We reported on one retraction in July, “Gustatory stimuli representing different perceptual qualities elicit distinct patterns of neuropeptide secretion from taste buds,” published in The Journal of Neuroscience.
The other, “Transformation of postingestive glucose responses after deletion of sweet taste receptor subunits or gastric bypass surgery,” published in 2012 in the American Journal of Physiology Endocrinology and Metabolism, was retracted in September. Here’s the note, which cites the university’s investigation: Read the rest of this entry »
A federal investigation into a paper on prostate cancer has now led to a retraction. In an unusual twist, it happened following a request from the animal rights group People for the Ethical Treatment of Animals (PETA).
In January, the Office of Research Integrity reported that corresponding author Dong Xiao “intentionally fabricated data” in an Oncotarget study of how a steroid inhibits the growth of prostate cancer. Xiao, a former cancer researcher at the University of Pittsburgh, claimed that he had tumor data from more mice than he did, and falsified several figures.
In July, after no sign of the retraction, a researcher at PETA followed up with the journal, Oncotarget, on behalf of the organization “and our more than 3 million members and supporters to request the immediate retraction.”
Last month, they received a reply from the publisher, which they forwarded to us:
A retired obstetrics and gynecology professor under federal investigation for misconduct has notched his ninth retraction.
The latest retraction stems from an investigation by the University of Florida, where Nasser Chegini worked until 2012, which found fabricated data in three figures in a paper on the muscle cells that line the uterus.
The paper, “Differential expression of microRNAs in myometrium and leiomyomas and regulation by ovarian steroids,” was published in The Journal of Cellular and Molecular Medicine. It’s been cited 74 times, according to Thomson Scientific’s Web of Knowledge.
Here’s the note:
The last of four papers containing data falsified by University of Oregon neuroscience student David Anderson has been retracted.
When the Office of Research Integrity report flagging the papers came out in July, Anderson told us he “made an error in judgment,” and took “full responsibility” for the misconduct.
The newly retracted paper, “A common discrete resource for visual working memory and visual search,” published in Psychological Science, has been cited 28 times, according to Thomson Scientific’s Web of Knowledge. According to the abstract, it demonstrates a possible link between working memory and the ability to “rapidly identify targets hidden among distractors.”
But according to the retraction note, Anderson produced “results that conformed to predictions” by “removing outlier values and replacing outliers with mean values” in some of the data.
Here’s the retraction note in full:
A paper containing data fudged by former University of California San Francisco grad student Peter Littlefield has been corrected. We knew that this was coming — last month, the Office of Research Integrity issued a report that Littlefield had admitted to misconduct, and agreed to a retraction or correction of the two affected papers.
Published in Science Signaling, “Structural analysis of the /HER3 heterodimer reveals the molecular basis for activating HER3 mutations” examined the structural details of a protein associated with cancer. It has been cited two times, according to Thomson Scientific’s Web of Knowledge.
According to the correction note, the concentration of a protein presented in one figure was “miscalculated;” in another figure, the error bars were “calculated incorrectly.”
Journals have retracted three out of the four papers flagged by the Office of Research Integrity during its investigation of a University of Oregon neuroscience student, David Anderson.
Last month, when we first reported on the case, Anderson told us that he “made an error in judgment,” and took “full responsibility.” Two of the retraction notes say that Anderson “knowingly falsified data,” and cited the Office of Research Integrity case summary.
All three papers focus on memory.
The note for the first retraction, from the Journal of Experimental Psychology: Human Perception and Performance, reveals exactly how Anderson falsified data in the paper. It’s paywalled — tsk, tsk — but printed here in full:

A former graduate student at the University of California, San Francisco “knowingly falsified and/or fabricated” data in two published papers, according to the Office of Research Integrity.
According to a case summary published this morning, Peter Littlefield was working on his PhD, studying the ways that cells respond to external signals, when he published the two problematic papers. He is the first author on the papers; Natalia Jura, whose lab he worked in, is the last on both.
The report’s findings are based on, among other sources, “the respondent’s admission.”
The first paper, “Structural analysis of the EGFR/HER3 heterodimer reveals the molecular basis for activating HER3 mutations” was published in Science Signaling and has been cited twice, according to Thomson Scientific’s Web of Knowledge.
Three figures in the paper are problematic, says the ORI summary:
