Figure 2. Mechanical overload and administration of capsaicin induce phosphorylation of p70S6K, S6, mTOR, Erk1/2 and p38 MAPK, but not Akt, AMPKα or GSK3β. Western blot analysis showing the effects of mechanical overload or administration of capsaicin on phosphorylation of p70S6K and S6 (A), mTOR (B), Akt (C), Erk1/2 and p38 MAPK (D), AMPKα (E) and GSK3β (F) (n = 3–4).
