Rate of 3-MG transport in paired muscles incubated for 19 h in the presence or absence of 100 μmol/l PUGNAc. During the final
75 min of incubation, muscles were exposed to 0, 0.6, or 12 nmol/l insulin. Data are mean ± SE (n = 12 per group). *Significant difference for with PUGNAc versus without PUGNAc for paired muscles incubated with 0.6 nmol/l
insulin (P < 0.05).
