Low phosphofructokinase activity increases glycogen biosynthesis in the heart. (A) Schematic of glycogen biosynthesis pathway. (B) Pool totals and isotopologue abundances for glycogen intermediates. (C) Representative NMR trace for glucose (Glc) and glycogen (Glyc) in WT mouse heart. (D) Abundance of 12C- and 13C-labeled glucose (Glc) and glycogen (Glyc) in the heart. n = 4–5 hearts per group, **p < 0.01, ***p < 0.001, ****p < 0.0001, one-way (B) or two-way (D) ANOVA with Tukey’s multiple comparison test.
