Relative expression values from microarray and real-time PCR experiments for A) igf1, B) igf2bp3, and C) igfbp2a. Values on the x-axis are the relative expressions in each group. In each graph the value for females are set to 1 as the reference for each group. F; female, M; male, Y; young, O; old. Error bars indicate the standard error, n =?6. *: p < 0.05.
