Calcipotriol ointment has been demonstrated to be a very safe and effective topical drug for psoriasis. This study aims to investigate the effect of calcipotriol on IFN-γ-induced keratin 17 (K17) expression in a human keratinocyte cell line (HaCaT), which is a widely accepted as a mimic in vitro model for psoriasis. We used Western blot, immunofluorescence staining, and luciferase reporter system assays to evaluate the expression of K17 and the possible underlying mechanisms. Administration of IFN-γ (125–1000 U) increased K17 expression in a dose-dependent manner, and 250 U/ml IFN-γ significantly elevated K17 expression. The experimental results showed that calcipotriol at concentrations of 10−7 M and 10−5 M suppressed the IFN-γ-induced K17 expression by 58.10% and 70.68%, respectively. Through immunofluorescence staining and luciferase reporter assay, we found that Vitamin D Response Element (VDRE) affected IFN-activated site (Gamma-activated sequence, GAS) function at the transcriptional level and was involved in the inhibition of K17 expression. Our data suggest that calcipotriol downregulates IFN-γ-mediated K17 expression in keratinocytes in a dose-dependent manner via VDRE effect GAS function. The inhibitory effect of calcipotriol on K17 expression may be a potential mechanism and function in the treatment psoriasis.
