Figure 2. Fractional protein synthesis rates (FSRs).

FSRs were measured in gastrocnemius (A) and soleus (B) muscles from adult and old rats in the four groups: C, INS−, AA–, INS–/AA–. Values are means ±s.e.m. and are expressed as percentage protein synthetized per day; n = 6–9 per group. Values not sharing the same letter differ significantly (P < 0.05) by ANOVA.
