Another paper in Diabetologia by Yoshiyuki Hattori has been retracted for image duplication, marking the second of his articles in the journal to be pulled for that reason.
This article has been retracted by the Editor-in-Chief of Diabetologia following the discovery of redundant publication (part of Figure 2c was previously published in Cardiovascular Research; doi:10.1093/cvr/cvn226).
The original Cardiovascular Research article, “Cilostazol inhibits cytokine-induced nuclear factor-κB activation via AMP-activated protein kinase activation in vascular endothelial cells,” was published online in August 2008. It has been cited 17 times, according to Thomson Scientific’s Web of Knowledge, while the Diabetologia version has been cited eight.
We’ll say this for Springer, which publishes Diabetologia: they make searching for retractions remarkably easy. In fact, they have a passive search function that does it for you: while you’re reading about one paper it calls up others and displays them in a window alongside the main paper. Bravo for that! Elsevier appears to have something similar, although it doesn’t appear to throw up retractions as often, at least in our limited sampling.
Update, 11:30 a.m. Eastern: A commenter points out that we missed one of Hattori’s retractions and failed to count a few from our other posts. (That’s why we love our readers, who keep us honest). The neglected article, “Statin blocks Rho/Rho-kinase signalling and disrupts the actin cytoskeleton: relationship to enhancement of LPS-mediated nitric oxide synthesis in vascular smooth muscle cells,” appeared in Biochimica et Biophysica Acta in 2004. Although we’d noted it in an earlier post as potentially problematic, at the time it had not been retracted. Here’s the notice:
The editors of the Journal of Cardiovascular Pharmacology and Biochimica et Biophysica Acta have discovered duplication of data in two manuscripts: “Disruption of the actin cytoskeleton up-regulates iNOS expression in vascular smooth muscle cells” (J. Cardiovasc. Pharmacol., 43 (2004) 209–213) and “Statin blocks Rho/Rho-kinase signaling and disrupts the actin cytoskeleton: relationship to enhancement of LPS-mediated nitric oxide synthesis in vascular smooth muscle cells” (Biochim. Biophys. Acta 1689 (2004) 267–272, doi:10.1016/j.bbadis.2004.04.006). We have requested an explanation from the authors, and an acceptable response has not been received. In the interests of scientific integrity, the editors of both journals have elected to retract both articles.
