Mean ± SE relative amounts of total and phosphorylated (p) p70 S6 kinase (S6K), ribosomal protein S6 (rpS6), 4E-binding protein-1 (4E-BP1), and Akt in 10 saline (Sal)-treated (gray bars) and 10 JA16-treated mice (black bars), as determined by immunoblotting. Representative bands are shown for proteins (S6K, rpS6) with increased phosphorylation (P < 0.05) in JA16-treated mice (P values for all proteins shown on right side of figure). The phosphorylated amino acids detected by the various anti-phospho 4E-BP1 and anti-phospho-Akt antibodies are shown next to the bars. The anti-phospho-S6K antibody detected phosphorylation at Thr (T)389. The anti-phospho-rpS6 antibody detected phosphorylation at Ser (S)235/236.
