Glucose uptake in porcine myotubes in response to insulin and cyto B. Glucose uptake was performed on differentiated porcine myotubes in the presence of varying concentrations of insulin (a), or varying concentrations of cyto B with (full circles) or without (open circles) 500 nM insulin (b). Control samples lacked cyto B. Data are expressed as LSmean values of four replicate wells, carried out in at least two separate experiments with cells isolated from a different pig each time. * denotes LSmeans with significant difference in responses with or without insulin; (P < 0.05).
