From: AMPK-induced activation of Akt by AICAR is mediated by IGF-1R dependent and independent mechanisms in acute lymphoblastic leukemia

Figure 7

Co-targeting AMPK and Akt signaling pathway induces synergistic cell death in ALL cell lines. Cell death values obtained from the ALL CCRF-CEM and NALM6 cells shown in Fig. 6 which were treated with either AICAR (100 μM) plus the IGF-1R inhibitor HNMPA(AM)3 (1.0 μM) (panel A); AICAR (200 μM) plus the Akt inhibitor-X (AIX, 9.0 μM) (panel B); or rapamycin (1.0 μg/ml) plus HNMPA(AM)3 (0.5 and 1.0 μM) (panel C). The cell death values were generated from the trypan blue exclusion data and are expressed as a percentage relative to those obtained with control cells (mean ± SEM, n = 3). Combination index (CI) values were determined for each drug combination as described in Methods (C <1, = 1, and >1 indicate synergism, additive effect, and antagonism, respectively).
