Last Ones Removed

The last papers out of a set of five from a former Pfizer researcher have been retracted, according to Retraction Watch.

Pfizer fired Min-Jean Yin, a cancer researcher, after it found that she had duplicated data and requested that five of her papers be retracted, Retraction Watch adds. It notes that three papers, appearing in Clinical Cancer Research and Cancer Letters, and Molecular Cancer Research, had previously been retracted, and two that appeared in PLOS One have now been removed.

Questions about some of Yin's work arose on PubPeer where commenters raised concerns about seemingly duplicated panels within figures. As Retraction Watch previously reported, an investigation by Pfizer found that nearly all the figures PubPeer commenters had concerns about were duplicated.

In the newly issued retraction notices, PLOS One notes that, for each paper, Pfizer and one of the authors contacted the journal about the duplications, and as Pfizer's investigation couldn't find the original images to verify the papers' conclusions, the journal has retracted the papers.
