Figure 2. AMPK agonists stimulate AMPK-dependent signal transduction in MEFs.
Immunoblot for AMPKα (Thr172 and total), ACC (Ser79 and total), raptor (Ser792 and total), p70S6K (Thr389 and total), 4E-BP1 (different phosphorylation states marked by arrows) and actin on lysates from WT or DKO MEFs. Cells were incubated with metformin (5mM), phenformin (1.25mM), AICAR (1.25mM), 2DG (12.5mM), salicylate (2.5mM) or A-769662 (25μM) for 1h.
