(A) AICAR (400 μM), an AMPK activator, mimics the effect of ghrelin. (B) Compound-C (30 μM), an inhibitor of AMPK, completely blocks the effect of oligomycin. (C) STO-609 (1 μM), a CAMKK2 inhibitor, partially reverses the effect of ghrelin. Ghrelin was applied at 100 pM (red bars). Traces are mean values from 5–20 cells.
