abstract：:Insulin stimulated protein kinase B alpha (PKB alpha) more than 10-fold and decreased glycogen synthase kinase-3 (GSK3) activity by 50 +/- 10% in skeletal muscle and adipocytes. Rapamycin did not prevent the activation of PKB, inhibition of GSK3 or stimulation of glycogen synthase up to 5 min. Thus rapamycin-insensiti...
