The Journal of Biological Chemistry is retracting four papers by a pair of cancer researchers at Tulane University, bringing their total to eight.
The retractions are all for reusing parts of figures, either within a paper or from other papers by the pair. Thanks to a new policy at the journal to publish informative notes, we know the figures that were problematic, and the papers that they borrow from.
An investigation by Tong Wu and Chang Han’s former employer, the University of Pittsburgh, had already led to four retractions for the pair, including two issued this summer.
First up, “Activation of cytosolic phospholipase A2α through nitric oxide-induced S-nitrosylation. Involvement of inducible nitric-oxide synthase and cyclooxygenase-2,” which has been cited 50 times, according to Thomson Scientific’s Web of Knowledge. Here’s the note: Continue reading Four JBC retractions add up to 8 in total for cancer research pair
