Insulin-like growth factor (IGF-I) is hypothesized to be a critical upstream regulator of mTOR-regulated protein synthesis with muscle contraction. We utilized a mouse model that expresses a skeletal muscle specific dominant-negative IGF-I receptor (MKR) to investigate the role of IGF-1 in signaling of protein synthesis in response to unilateral lengthening contractions (10 sets, 6 repetitions, 100Hz) at 0 h and 3 h following the stimulus. Our results indicate that one session of high frequency muscle contractions can activate mTOR signaling independent of signaling components directly downstream of the receptor.
