Fig. 7. Relative expression of myogenin RNA expression in red muscle of GH-transgenic and non-transgenic Atlantic salmon at 4 and 7 months of age. Sample size equals 11 for transgenic salmon at 4 months, 10 for non-transgenic salmon at 7 months and 10 for transgenic salmon at 7 months. Results are means ± s.e.m. Myogenin data were log transformed to obtain normality. Data were analysed using one-way ANOVA, P=0.001 (Tukey–Kramer, <0.05). Red muscle could not be sampled from control salmon at 4 months due to the small size of the fish. Different letters indicate significant differences. See Fig. 4 legend for the definition of relative expression. (B) Picture of the gel used to analyse band intensities.
