Not our problem: Journal bows out of data dispute after U Minn challenges previous statement

cellcyclecoverBack in May we reported on an Expression of Concern in Cell Cycle — a notice that had entered life as a retraction but mysteriously metamorphosed into the less dramatic form. The statement limned a rather bizarre dispute between researchers who crossed paths at the University of Minnesota and are now embroiled in litigation over ownership of the data.

Now, it gets weirder. Responding to further correspondence from the university, the journal has effectively washed its hands of the matter — without bothering to wipe down the sink or hang up the towel.

Here’s the “Comment on Expression of Concern“: Continue reading Not our problem: Journal bows out of data dispute after U Minn challenges previous statement

Amid a legal dispute, journal downgrades a retraction to an expression of concern

cellcyclecoverThe journal Cell Cycle is expressing a “note” of concern about a 2012 paper by a former researcher at the University of Minnesota, who has claimed that her mentor at the institution was violating her copyright. It turns out the journal had briefly retracted the paper, but reversed itself with the expression of concern — a curious about-face that, in our experience, often indicates the work of lawyers.

That seems to be the case here, too.

The article, “Chalcone-based small-molecule inhibitors attenuate malignant phenotype via targeting deubiquitinating enzymes,” was already the subject of an erratum, available here:

Dodgy figure in cord blood paper prompts Expression of Concern in oncology journal

cmionccoverThe editor of Clinical Medicine Insights: Oncology has issued an Expression of Concern over a 2008 paper by a group of authors in China after identifying “flaws” in one of the figures.

The article, “Exvivo experiments of human ovarian cancer ascites-derived exosomes presented by dendritic cells derived from umbilical cord blood for immunotherapy treatment,” purported to show that:

tumor-specific antigens present on exosomes can be presented by DCs [dendritic cells] derived from unrelated umbilical cord blood to induce tumor specific cytotoxicity and this may represent as a novel immunotherapy for ovarian cancer.

But according to William C. S. Cho, editor of the journal, there’s reason to doubt the conclusions. As the notice explains:

BMC Genomics has issued an expression of concern for a 2011 paper by a prominent Argentine chemist, Ariel Fernandez, whose work covers several disciplines — “His research spans representation theory in algebra, physical chemistry, molecular biophysics, and more recently, molecular evolution and drug discovery” — and institutions. And therein lies the tale.

Fernandez appeared as the first author of the article, titled “Subfunctionalization reduces the fitness cost of gene duplication in humans by buffering dosage imbalances,” along with a pair of researchers from Taiwan. Fernandez’s affiliations were listed as being with the Instituto Argentino de Matemática “Alberto P. Calderón”, CONICET (National Research Council of Argentina), in Buenos Aires, the Department of Computer Science at the University of Chicago, and the Morgridge Institute for Research, in Madison, Wisc.

According to the abstract:
