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:

Author break prompts retraction of bone protein paper

ejpcoverThe European Journal of Pharmacology has — against its will, it would seem — retracted a 2012 paper by a group of Chinese heart researchers embroiled in a what appears to be a rather messy authorship dispute.

The article, “The effect of alendronate on the expression of osteopontin and osteoprotegerin in calcified aortic tissue of the rat,”  came from the Institute of Cardiovascular Disease at Tongji Hospital, part of of Huazhong University of Science and Technology.

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:
