Figure 3: AMPK activation mediated dasatinib-induced ER stress and EGFR degradation. (A) The effect of dasatinib on AMPK activation. Cells were treated with dasatinib (1uM) for indicated intervals. The expression of p-AMPK and AMPK was evaluated. (B) The effect of AMPK knockdown on dasatinib-induced EGFR degradation and ER stress. Cells were treated with control or AMPK siRNA and then with dasatinib for 24 hours. (C) The effect of AMPK activation on dasatinib-induced EGFR degradation. Cells were treated with dasatinib with or without AICAR (10uM) for 24 hours. The expression of EGFR p-eIF2α, and AMPK was evaluated. (D) The correlation between p-AMPK and EGFR expression. Left, the expression of EGFR, p-AMPK, and AMPK in HNSCC cells. Right, the correlation of p-AMPK and EGFR expression in resected human specimens. Pearson’s correlation coefficient=0.659; *, p<0.01.

Figure 4: Dasatinib induced cellular ATP decrease and PDK4 up-regulation. (A,B) The effect of 6-hr or 18-hr dasatinib (1uM) on cellular ATP (A) and glucose (B) levels. *, p<0.05. (C) The expression of PDK4 and p-Erk in HNSCC cells treated with dasatinib (1uM) for indicated intervals.
