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
PLOS Biology has retracted a paper about the molecular details of β-catenin expression following an investigation by the first author’s institution in Italy.
The investigation, by the Istituto Nazionale per la Ricerca sul Cancro, found that there were multiple “figure anomalies.” According to the note:
An explanation of inadvertent error was given for some of the issues identified, while for two issues, a satisfactory explanation could not be provided.
First author Roberto Gherzi says none of his co-authors helped prepare the figures. The authors maintain that the conclusions are unaffected, but that assurance wasn’t enough for the journal. Here’s more from the lengthy retraction note, which provides some backstory on the “serious concerns” regarding the data:

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 an anti-fungal bacterium couldn’t ward off a very common problem: plagiarism. The people credited on the paper, published in Applied Microbiology and Biotechnology, apparently weren’t the original authors, according to the retraction note.
We’re not sure who the original authors are. The retraction note doesn’t elaborate much:

A review article about a tool used to link genes to traits and behaviors has been retracted for including content “without permission and/or proper reference.”
Corresponding author Ali Masoudi-Nejad at the University of Tehran told us that the retraction occurred mostly because the paper included many figures and tables from other sources, and he didn’t realize they needed to seek permission from both the author and the copyright-holder (ie, the publisher). He added that he doubts he is the only one to make this mistake: Continue reading Genetics paper retracted for using material “without permission and/or proper reference”
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:
Two sets of authors have withdrawn their papers from the Journal of Biological Chemistry. We’re telling you about the both together because, true to JBC form, there’s not too much to say.
The retraction notices for both papers — about the molecular underpinnings of cardiac fibroblasts and melanoma cells — are identical:

A journal has issued a rather large correction — what we call “mega-correction” — to a 2014 paper on a gastric cancer biomarker that fixes problems with several of the study’s figures.
The authors write that despite the corrections, “the results and conclusions put forth in the article remain unchanged.”
The paper, “TMEFF2 Deregulation Contributes to Gastric Carcinogenesis and Indicates Poor Survival Outcome” explored the role of TMEFF2 in gastric cancer. The researchers found that the protein acts as a tumor suppressor, and low levels can indicate the presence of cancerous cells.
Here’s the full correction notice, published by Clinical Cancer Research in August:
