The paper described a new way to deliver gemcitabine via nanoparticles, focusing the drug on the tumors. It turns out the … Continue reading Drug paper gets a fix, notching several corrections

Cell biologists in South Korea retract two papers

A group of researchers at two universities in South Korea have retracted two cell biology papers featuring retinoic acid. The most recent retraction appears in the Journal of Biological Chemistry. Although, in typical JBC fashion, the reason for it is anyone’s guess. Here’s the unhelpful notice for “ASXL1 represses retinoic acid receptor-mediated transcription through associating … Continue reading Cell biologists in South Korea retract two papers
