Liver and muscle metabolites.A, liver glucose-6-phosphate, (B) muscle glucose-6-phosphate, (C) liver triacylglycerol, and (D) muscle triacylglycerol in sedentary and exercised control and PTGOE mice under fed and fasting conditions (n = 8–12 in all experiments). All values are the mean ± SEM. ∗p < 0.05 and ∗∗∗p < 0.001. PTG, protein targeting to glycogen; PTGOE, overexpressing PTG specifically in the liver.
