摘要
This study investigated the effects young leaves of reed (Phragmites communis) water extract (YLR) on melanogenesis and oxidative stress using B16F10 cells. YLR decreased the intracellular melanin content, protein expression and enzyme activity of tyrosinase in a dose-dependent manner. YLR significantly decreased the gene and protein expression of melanogeneis-related proteins, such as microphthalmia-associated transcription factor (MITF), and tyrosinase-related protein-1 and -2. In addition, YLR up-regulated the melanogenesis inhibitory proteins, extracellular signal-regulated kinase (ERK) and protein kinase B (AKT), while it dose-dependently down-regulated p38 and cAMP response element-binding protein (CREB). Moreover, YLR significantly reduced H2O2-induced reactive oxygen species levels in B16F10 cells and showed antioxidant activity based on DPPH and ABTS free radical scavenging activity and SOD-like activity. These results suggest that YLR have anti-melanogensis properties that function through regulation of the CREB/MITF/tyrosinase pathway in B16F10 cells and antioxidant activity. Overall, these findings indicate that YLR has the potential for use in treatment of skin disorders and skin-whitening.
