Acute inhibition of protein deacetylases does not impact skeletal muscle insulin action

Whether the histone deacetylase (HDAC) and sirtuin families of protein deacetylases regulate insulin-stimulated glucose uptake, independent of their transcriptional effects, has not been studied. Our objective was to determine the nontranscriptional role of HDACs and sirtuins in regulation of skeletal muscle insulin action. Basal and insulin-stimulated glucose uptake and signaling and acetylation were assessed in L6 myotubes and skeletal muscle...
