Curcumol may alleviate psoriasis-like inflammation by inhibiting keratinocyte proliferation and inflammatory gene expression via JAK1/STAT3 signaling

Curcumol promotes differentiation in M5-stimulated NHEK cells. 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) Expression of keratin 1, keratin 5, keratin 10, filaggrin and loricrin in NHEK cells was analyzed by western blotting. (B–F) The relative expression of keratin 1 (B), keratin 5 (C), keratin 10 (D), filaggrin (E), and loricrin (F) quantified via normalization to β-actin. **P#P##P<0.01 compared with 10 ng/mL
