Figure 4: Correlations between phosphorylated mechanistic target of rapamycin and plasma Leu (a), and overall BCAAs levels (b). Phosphorylated p70S6K and total BCAAs levels (c). Phosphorylated 4E-BP1 and total BCAAs levels (d). Data were analyzed as two-tailed of significance using Pearson's correlation coefficients (n = 40) assumed P < 0.05. PLA: Placebo; BCAAs: Branched-chain amino acids; Leu: Leucine.
