AMPK of control (white bars) and PTGOE (black bars) mice under fed or fasted conditions. (A, E) Total and (A, C) phosphorylated AMPKβ and (B, F) total and (B, D) phosphorylated AMPKα measured by western blot. (G) Phosphorylated to total AMPKα is provided as a ratio (A.U). (H) Phosphorylated to total AMPKα is provided as a ratio (A.U). (I) Amount of AMPKβ and AMPKα in homogenates, supernatant, and 100 000 g pellet fraction. Data are presented as mean ± SEM. *P < 0.05, **P < 0.01, and ***P < 0.001. n = 8.
