Figure 2. Protein mass and fractional growth rates.

Figure 2

Protein mass and fractional growth rates of pooled gastrocnemius, tibialis anterior and quadriceps muscle from one hind limb of Control mice, mice undernourished from PN1 to PN11 (Early-UN) or PN11 to PN22 (Late-UN), or refed (RF) for 2 days, 7 days, 21 days or 18 months (protein mass only). Protein mass is normalized for bone length. Fractional growth rates were calculated using the first derivative of a polynomial that described the change of muscle protein mass with age for each litter. Values are least square means ± SEM; n = 7–8 litters per treatment group.*Significant difference between age-matched groups where age×group is significant.
