Phosphorylation of Akt/PKB, S6K1, 4E-BP1 and eEF2 in older volunteers at baseline and during the intra-arterial infusion of insulin at two different rates, chosen to increase the femoral vein insulin concentrations to either a postprandial level (PD: n=6 for Akt/PKB and S6K1; n=5 for 4E-BP1 and eEF2) or a supraphysiological high level (HD: n=6 for all proteins). Values are the mean ± SE. *P < 0.05 vs. Basal; ‡P = 0.07 vs. PD; #P<0.05 vs. PD
