Figure 3.
Phosphorylation of AKT/p70S6K in A549 cells treated with DK-1014. A549 cells were pre-treated with DK-1014 or DEX for 1 h and then incubated for 30 min with PMA (5 nM). (a) Phosphorylation of AKT/mTOR protein evaluated using western blot analysis and (b) quantified using ImageJ. (c) Immunocytochemical staining with anti-phosphoAKT antibodies for A549 cells that were DK-1014 treated or inhibitors (magnification = ×100, bar; 100 μm). #p < 0.05 compared to DMSO-treated cells; **p < 0.005 compared to PMA-treated cells.
