Fig. 3. Expression profiles for IGF-I, IGF-II, and IGF receptors IGFR1a, IGFR1b and IGF2R in fast skeletal muscle of Atlantic salmon from fish with zero growth rate (0 days) that were then fed to satiation and sampled at 3, 5, 7, 14, 30 and 60 days. Gene expression was normalised to the geometric average of three reference genes (Genorm analysis); see text for details. Values represent means ± s.e.m., 10 fish per sample point. Significant differences between means are indicated by different letters.
