An investigation at the University of New South Wales in Australia has determined that a long-accused cancer researcher did not commit misconduct.
The investigation did find instances when Levon Khachigian breached the code of conduct, but Continue reading Cancer researcher cleared of misconduct, inquiry finds “genuine error or honest oversight”
Robert Weinberg, a prominent cancer researcher at the Whitehead Institute, issued a correction to a paper in Oncogene in May, fixing two errors missed during proofing.
We found this one a little late, obviously. It also appears to be a relatively minor correction, not one that appears worthy of retraction. We’ve gotten feedback from readers asking why we cover corrections; we chose to flag this one because Weinberg has had such an impact on his field — he discovered the first tumor-causing gene in humans, as well as the first tumor-suppressor gene — and his papers are often highly cited. He also has issued five retractions in the past, most of which for papers whose first author was a member of his lab, who is not a co-author on the Oncogene paper.
Here’s the correction note for “Thrombospondin-1 repression is mediated via distinct mechanisms in fibroblasts and epithelial cells:”

Is ethical behavior good for business?
Five years ago this month, Swedish pharmaceutical company WntResearch immediately notified shareholders when authors retracted a 2009 Proceedings of the National Academy of Sciences (PNAS) paper on a potential cancer therapy that was key to the company’s business.
At the time, the company’s decision to disclose the retraction hurt its finances, as WntResearch delayed its planned initial public offering for three weeks. It also offered investors and shareholders the opportunity to withdraw their shares of WntResearch stock.
But, aside from one of the paper’s co-authors, “No one did that,” Nils Brünner, WntResearch’s CEO, told us. Since the company’s IPO on December 17, 2010, its stock price has increased from Continue reading Five years after a retraction, company’s stock is up more than 500%
A 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:

A PLOS One paper on morphine treatment for cancer cells has a couple issues with figures, prompting a massive correction — what we affectionately call a “mega-correction” — by the journal.
In one figure, there was “an undisclosed splice.” Another figure contained two panels that were “mistakenly from the same sample.”
The 2013 paper in question, “Chronic Morphine Treatment Attenuates Cell Growth of Human BT474 Breast Cancer Cells by Rearrangement of the ErbB Signalling Network,” has been cited four times, according to Thomson Scientific’s Web of Knowledge.
Here’s the correction:

Maynooth University has revoked a former student’s PhD following an investigation into the circumstances that led to two previous retractions in the Journal of Biological Chemistry.
During the investigation, Aisha Qasim Butt admitted to some misconduct in the two papers and the research that made up her PhD, according to a university statement (which you can read in full here): Continue reading Irish university strips student of PhD following investigation
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:

Science is fixing images in a paper published online in April that discovered an immune-boosting protein, after the authors mistakenly mixed up similar-looking Western blots.
The paper, which received some press coverage, identified a protein that helped the immune system fight off cancers and infections. Philip Ashton-Rickardt, a scientist at Imperial College London who led the study, told the The Telegraph:
This is exciting because we have found a completely different way to use the immune system to fight cancer.
The editor in chief of Science, Marcia McNutt, told us that the journal contacted the authors once it learned of “irregularities” in some of the figures, which did not affect the conclusions of the paper:
The authors of a paper on a mechanism for potential cancer therapies are retracting it after realizing they published some proprietary findings “without permission and agreement from St. Jude Children’s Research Hospital.”
According to the retraction note in Journal of the American Chemical Society, the authors included an X-ray crystal structure and data that were gathered at St. Jude’s and considered the hospital’s intellectual property. On the paper, the last author, Zhengding Su, listed an affiliation at St. Jude and Hubei University of Technology in China, along with Amersino Biodevelop Inc., based in Waterloo, Canada.
Here’s the note for “Efficient Reactivation of p53 in Cancer Cells by a Dual MdmX/Mdm2 Inhibitor:” Continue reading Intellectual property issues sink cancer paper in JACS
A 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:
