Figure 6. Curcumol inhibits proliferation of M5-treated NHEK cells via downregulation of JAK1/STAT3 signaling. (A) NHEK cells were treated with curcumol (10 or 20 μM; 24 h), and stimulated with M5 (10 ng/mL; 24 h). Levels of p-JAK1 were analyzed by western blotting, and normalized to JAK1. (B) NHEK cells were treated with 20 μM curcumol or/and 3μM ruxolitinib (RUX) for 24 h, and then stimulated with M5 (10 ng/mL) for 24 h. Levels of p-STAT3 were analyzed by western blotting, and normalized to STAT3. **P<0.01 compared with control group; #P<0.05, ##P<0.01 compared with M5 group; ^^P<0.01 compared with M5 + RUX group.
