Abstract
BackgroundVitiligo is classified as an acquired chronic depigmentation disorder that includes the destruction of epidermal melanocytes. It affects 0.5–1% of the population all over the world. Wnt signaling pathway is vital in melanocytes differentiation and development. WIF-1 is an antagonist of the Wnt signaling pathway; it hinders Wnt from binding its receptors. The present study aims to detect WIF-1 expression in vitiligo skin and if it relates to the disease's severity.ResultsThis case–control study included 70 subjects: 35 vitiligo patients and 35 healthy controls. Skin WIF-1 expression was estimated using quantitative real-time PCR. Assessment of the vitiligo disease activity score and vitiligo area severity index score was determined. WIF-1 expression showed significant elevation in the skin of vitiligo patients compared to the healthy control group.ConclusionOverexpression of WIF-1 may participate in the pathogenesis of vitiligo; hence, it should be a future therapeutic target.
