Collaborations can be fraught. Ask David Ojcius. 

Ojcius, an emeritus professor of molecular and cell biology at the University of California, Merced, and a department chair at the University of the Pacific, is up to four retractions, five corrections and an expression of concern in papers he wrote with collaborators in China and elsewhere. 

Ojcius is the editor-in-chief of Microbes and Infection, which has retracted one of his papers and corrected another.

An investigation by the University of Tennessee Health Sciences Center, in Memphis, into a 2006 Science paper found evidence that three figures in the article had been manipulated.

Science sleuth Elisabeth Bik first flagged the paper, titled “Molecular Linkage Between the Kinase ATM and NF-κB Signaling in Response to Genotoxic Stimuli,” to the editors of Science in 2015. Today, Science issued an expression of concern for the paper:

A researcher at the University of Maryland, along with two former colleagues, has had three papers retracted in the past six months following an institutional investigation that found evidence of image manipulation.

The three retractions share three authors: Hua Zhou, Ying Hua Yang and John Basile, an associate professor of oncology and diagnostic sciences at the institution. The original papers appeared in Angiogenesis and PLOS ONE between 2011 and 2013.

Basile told Retraction Watch that he was prohibited from discussing the matter, based on statements from the university’s investigation committee, but that he did not think other papers from his lab co-authored with Zhou would be retracted.

One of the articles, “Semaphorin 4D cooperates with VEGF to promote angiogenesis and tumor progression,” has been cited 46 times, according to Clarivate Analytics’ Web of Science. Here’s the retraction notice from Angiogenesis, which was published earlier this month:

King’s College London (KCL) found evidence of poor research practices by three of its faculty, but “no intention to deceive” and no misconduct, according to documents obtained by Retraction Watch.

One case involves work by cancer biologists Farzin Farzaneh and Ghulam Mufti, while the other involves work by Mahvash Tavassoli, also a cancer researcher. Both involve problems with images and were brought to the attention of KCL in January of this year by pseudonymous whistleblower Claire Francis.

In the Farzaneh and Mufti case, writes Tim Newton, KCL’s dean of research governance, ethics and integrity in an October 31 letter:

A researcher who is now up to six retractions has left his faculty position at the Rosalind Franklin University of Medicine and Science following a finding of research misconduct, Retraction Watch has learned.

Gulam Waris, who studies hepatitis, has reused images across multiple papers, according to a retraction notice published this week in the Journal of General Virology:

Retraction Watch readers may know the name Elisabeth Bik, whose painstaking work inspecting tens of thousands of Western blot images has led to dozens of retractions in journals including PLOS ONE. Today in The Scientist, we profile Bik, a microbiologist who calls herself a “super-introvert.”

Bik tells us:
