Abstract
- Ultraviolet (UV) radiation is the main physiological stimulus for human skin pigmentation. Recently, nitric oxide (NO) have been involved in mediation of skin pigmentation induced by UVB. Rutin, a flavonoid of vegetables and fruits, has antiviral and antioxidant properties. Therefore, we investigated the effect of rutin on UVB-induced melano-genesis and NO production in HM3KO cells. In this study, we demonstrated that UVB-irradiation stimulated melanin content and tyrosinase activity in HM3KO cells. Rutin suppressed UVB-stimulated total melanin content and tyrosinase activity in a dose-dependent manner. Additionally, we showed that UVB-irradiation stimulated NO production in HM3KO cells. Rutin also suppressed UVB-induced NO production and repaired reduction of cell proliferation by UVB. UVB stimulation of melanogenesis was mimicked by exogenous NO donor (sodium nitroprusside, SNP), and rutin effectively suppressed it. Therefore, we concluded that rutin suppressed UVB-stimulated melanogenesis and that it is involved in melanogenesis regulation partially through the suppression of UVB-induced NO production.
