WebDec 1, 2016 · To confirm Glut1 acetylation, Glut1 was immunoprecipitated and acetyl-lysine was analyzed on a western blot. A band specific for acetyl-lysine was found to run at the same place on a gel as that for Glut1 (Fig. 6G). Again, the acetylation status of Glut1 was unaffected by piericidin A or antimycin A treatment (Fig. 6G). The above results ... Weblevel of Glut1 acetylation. Stimulation of glucose uptake was greatly reduced by chemical inhibition of Sirt2 or mTOR–RAPTOR. We propose that mitochondrial dysfunction triggers LKB1-mediated AMPK activation, which stimulates Sirt2 phosphorylation, leading to activation of mTOR–RAPTOR and Glut1-mediated glucose uptake. city of fort myers fire department https://pkokdesigns.com
