Figure 6. Effect of honokiol on STAT-3 phosphorylation in gastric cancer cells and HUVECs.
AGS (A) and MKN45 (B) quiescent human gastric cancer cells and HUVECs (C) were treated with and without honokiol (HK, 5–40 µM) for the indicated times. Whole cell lysates were prepared and analyzed by Western blotting for detection of phosphorylated STAT-3 (pSTAT-3, Tyr705). The blottings were reprobed with anti-STAT-3 antibodies for normalization. The results are representative of at least five independent experiments.
