Retraction of DiabetologiaDOI 10.1007/s00125-011-2276-4Abstract 59, presented at the 47th Annual Meeting of the EASD in 2011, has been retracted at the request of the Dean of Sahlgrenska Academy at the University of Gothenburg, Professor Larkö. The University has investigated this case and The Committee on Academic Misconduct finds that Pontus Boström is guilty of misdemeanour with reference to the points (1) conscious fabrication, corruption or suppression of basic material, and (2) conscious preparation and presentation of falsified results, and therefore finds reason to believe that scientific misconduct has occurred. The primary finding reported in the abstract—reduced protein levels of syntaxin-5 in diabetic muscle—could not be reproduced.
