Almost 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 … Continue reading Stem cell researcher in Korea up to half a dozen retractions
A retraction from a high-profile group uncovered a technical limitation involving a widely used reagent. Some quick background: the sequence hypothesis central hypothesis dogma of biology states that DNA gets transcribed to RNA that gets translated into proteins. Some RNAs, however, don’t code for proteins, but instead help to regulate gene expression. These microRNAs are tiny … Continue reading Group retracts microRNA paper after realizing reagent was skewing results
Last month, we brought you the story of Soo-Kyung Kang, a Seoul National University stem cell researcher who has now retracted four papers amidst questions about image manipulation in a total of 14 studies. That story has drawn a great deal of attention in Korea, with comparisons to the Woo-Suk Hwang scandal, and has even led to a … Continue reading Korean stem cell investigation expands to another researcher, and more papers
In a case that is a good reminder of why journal editors shouldn’t ignore anonymous tips, a Seoul National University stem cell researcher has been forced to retract four papers, and withdraw another under peer review, in Antioxidants & Redox Signaling following a whistleblower’s exhaustive analysis. Two retractions by Soo Kyung Kang, a professor of … Continue reading Whistleblower forces retractions of four stem cell papers amid questions about more than a dozen studies
Antioxidants & Redox Signalling has issued much more detailed retraction notice for a paper it pulled last year that was marred by duplicate data. As we reported then, the journal’s initial notice for the 2011 article, titled “Inhibition of LXRa-dependent steatosis and oxidative injury by liquiritigenin, a licorice flavonoid, as mediated with Nrf2 activation,” was … Continue reading Redox, redux: Journal pulls paper over data problems
