Curcumol may alleviate psoriasis-like inflammation by inhibiting keratinocyte proliferation and inflammatory gene expression via JAK1/STAT3 signaling
Figure 5. Curcumol inhibits proliferation of M5-treated NHEK cells via downregulation of p-STAT3/cyclin D2 axis. NHEK cells were treated with curcumol (10 or 20 μM) for 24 h, and then stimulated with M5 (10 ng/mL) for 24 h. (A) The expression level of p-STAT3 in NHEK cells was detected by western blotting, and normalized to STAT3. (B) The nuclear levels of p-STAT3 were analyzed by western blotting, and normalized to Histone H3. (C) Cyclin D2 mRNA levels were analyzed by RT-qPCR. (D) Cyclin D2 protein levels were analyzed by western blotting, and normalized to β-actin. **P<0.01 compared with control group; ##P<0.01 compared with 10 ng/mL_M5 group.
