bFGF up-regulated the phosphorylation of Akt and mTOR. a Western blot analysis of phosphorylation of Akt and mTOR levels in skeletal muscle tissues of saline group and bFGF group at indicated time. Actin was used as the loading control, and total Akt and mTOR were used for band density normalization. All of the experiments were repeated three times. b, c The optical density analysis of phosphorylation of Akt and mTOR levels. Data are expressed as mean ± SEM (n = 3). *P < 0.05 compared with saline group
