Over the past week, there have been a number of comments on PubPeer — a site of which we’re big fans — about a 2007 paper in Oncogene.

The comments suggested that the figures in the paper had problems. Some bands seemed to be duplicated, and one of the images looked very much like that of another paper.

Then, today, first author Eriko Suzuki left this comment: Continue reading Brutal honesty: Author takes to PubPeer to announce retraction — and tells us she’ll lose PhD, professorship

Stem cell researcher in Korea up to half a dozen retractions

stem cellsAlmost two years ago, we brought you — with the help of Trevor Stokes — the story of a stem cell researcher in Korea whose publication record, and career, unraveled after evidence of image manipulation surfaced in her work.

We’ve reported on four retractions, all in Antioxidants & Redox Signaling, by Soo-Kyung Kang, formerly of Seoul National University resulting from the efforts of a whistleblower. There has been another in Human Gene Therapy: Continue reading Stem cell researcher in Korea up to half a dozen retractions
