After questions from a reader, researchers took a second look at their data about the effects of a vitamin A metabolite on tumor cells, and realized their key finding was inaccurate.
They’re now retracting the paper, from Molecular Medicine Reports, because it originally reported that higher concentrations of retinoic acid (RA) were more effective in curbing the proliferation of brain tumor cells. But it seems that the RA dose made less of a difference than they originally believed, according to the retraction notice:

Researchers at Qingdao University have fully retracted a paper originally published in Molecular Medicine Reports with a clear, detailed outline of what went wrong and how they discovered the error.
