Differences in the expression of SOCS2, CIS, myostatin (MSTN), AR, and ERα between wild-type (WT) and STAT5B^−/− mice. Mean (± SEM) expression of a Socs2 mRNA, b Cis mRNA, c Mstn mRNA and d protein, e Ar mRNA and f protein, and g Era mRNA and h protein in quadriceps muscles of male WT (black bars), male STAT5B^−/− (light grey bars), female WT (dark grey bars), and female STAT5B^−/− (white bars) mice at 6, 12, and 24 weeks of age (n = 8 per group). Values for each group are presented relative to expression in male WT mice at 6 weeks of age. Unlike letters within each graph denote significant differences (P < 0.05) between groups at each age only
