|
Purpose: This study was performed to elucidate the inhibitory effect of Mibaeksan (MB) on melanin synthesis in B16F10 mouse melanoma cell.
Methods: To demonstrate the inhibitory effects of MB on melanin synthesis, we measured the amount of released and produced melanin in B16F10 melanoma cell. Also, we evaluated tyrosinase-activity in vitro as well as in B16F10 melanoma cell. And to investigate the action mechanism, we assessed the gene expression of tyrosinase, TRP-1, TRP-2, MMP-2, PKA, PKCβ, ERK-1 ERK-2, AKT-1 and MITF in B16F10 melanoma cells.
Results: 1. MB decreased the release and production of melanin in B16F10 melanoma cells. 2. MB decreased tyrosinase activity in vitro and in B16F10 melanoma cells. 3. MB decreased the expression of tyrosinase, TRP-1, TRP-2, PKA, PKCβ and MMP-2 in B16F10 melanoma cells. 4. MB increased the expression of ERK-1, ERK-2 and AKT-1 in B16F10 melanoma cells. 5. MB decreased the expression of MITF in B16F10 melanoma cells.
Conclusion: From these results, it may be concluded that MB has the antimelanogenetic effects.
