Inhibitory effect of Cyrtomium falcatum on melanogenesis in α-MSH-stimulated B16F10 murine melanoma cells

摘要

Objective:To explore the anti-melanogenic potential of Cyrtomium falcatum.Methods:The effects of Cyrtomium falcatum crude extract and its solvent fractions on tyrosinase activity,melanin content,and the expressions of melanogenesis-related genes and proteins were analyzed inα-melanocyte-stimulating hormone(α-MSH)-stimulated B16F10 cells.Results:α-MSH treatment significantly increased tyrosinase activity,and extracellular and intracellular melanin content,as well as the expression levels of tyrosinase,microphthalmia-associated transcription factor(MITF),tyrosinase-related protein(TRP)-1,and TRP-2 in B16F10 cells.Treatment with Cyrtomium falcatum crude extract and its solvent fractions reduced tyrosinase activity and extracellular and intracellular melanin content and downregulated the expression levels of tyrosinase,MITF,TRP-1,and TRP-2 in a dose-dependent manner.Conclusions:Cyrtomium falcatum has potential anti-melanogenesis effects and can be used as a potential source material in cosmeceutical industry for the research and development of novel lead molecules with whitening properties.
