An international team of researchers from the NIH, Harvard, the University of Michigan, and two Chinese universities — Fourth Military Medical University and China Medical University — has retracted their 2012 paper in Nature after they — and a number of other groups — were unable to reproduce the key results.
The original abstract for “The NAD-dependent deacetylase SIRT2 is required for programmed necrosis” said that the findings
implicate SIRT2 as an important regulator of programmed necrosis and indicate that inhibitors of this deacetylase may constitute a novel approach to protect against necrotic injuries, including ischaemic stroke and myocardial infarction.
We have an update on the case of Pankaj Dhonukshe, a scientist about whom we reported in November. Utrecht University has found that Dhonukshe, a former researcher at the Dutch university, committed “a violation of academic integrity” in work that led to a number of papers, including one published in Nature and once since retracted from Cell.
Blood has retracted two 2013 illustrations of red cells by researchers from South Africa and the United States because, somewhat confusingly, they didn’t conform to the journal’s criteria for publishing such material.
Two cancer researchers who hold a patent on a particular pathway that might be a target for new drugs — and one of whom leads a company that is studying those potential drugs — have retracted two related papers in the Journal of Biological Chemistry (JBC).
The notices for “Kinase suppressor of Ras signals through Thr269 of c-Raf-1“ and “The kinase activity of kinase suppressor of Ras1 (KSR1) is independent of bound MEK,” which share H. Rosie Xing and Memorial Sloan-Kettering’s Richard Kolesnick as authors, say the same thing: Read the rest of this entry »
