Objectives : The Skin is composed of multiple layers, including the epidermis, dermis, and hypodermis. It provides a vital barrier structure that protects vertebrates from external environmental antigens, solvents, ultraviolet light, microorganisms, toxins, and weather conditions. Although several biological effects of Mori Follium have been reported, beneficial effects of Mori Follium in skin health remain unclear. In this study, we prepared water extract of Mori Follium (MLE) and evaluated the effects on melanin accumulation and expression levels of skin fibril-related proteins.Methods : The cytotoxicities of MLE in B16F10 melanoma and human skin fibroblasts (HSF) were examined by MTT assay. Inhibitory effect of MLE on the α-MSH- and IBMX-induced melanosis in B16F10 melanoma was examined. The expression levels of fibronectin, collagen 1α2, and CCN2 in MLE-treated HSF were analyzed by reverse transcription-polymer chain reaction (RT-PCR) and western blotting.Results : The MLE treatment for 24 h did not affect to the B16F10 and HSF at concentrations of 1, 10, 50, 100, 200, 400 and 800 ㎍/ml. The MLE treatment for 72 h significantly and dose dependently suppressed melanin accumulation in B16F10 melanoma. In addition, the MLE treatment up-regulated expression levels of skin fibril-related genes such as fibronectin, collagen 1α2, and CCN2 in HSF. Our western blot analysis revealed MLE-induced up-regulation of skin fibril-related genes required the activation of CCN2 protein.Conclusions : In conclusion, these findings suggest that the MLE could be used in development of cosmetic natural material of maintaining healthy skin.
