Abstract:
Background:Actinidia polygama (silver vine) has been used in oriental medicine to treat gout, rheumatoid arthritis, and inflammation. Actinidia polygama water extract (APWE) is named PB203.
Objective:To investigate whether PB203 has anti-photoaging effects and to understand the molecular mechanism underlying such effects.
Methods:The antioxidant effect was assessed by 1,1-diphenyl-2-picrylhydrazyl assay and 2′,7′-dichlorodihydrofluorescein diacetate staining in ultraviolet B (UVB)-irradiated HaCaT cells with or without PB203 treatment. Type I collagen, matrix metalloproteinase-1 (MMP-1), tissue inhibitor of metalloproteinase (TIMP-1), hyaluronic acid (HA), hyaluronan synthase 1 (HAS1) and HAS2 levels were measuring by enzyme-linked immunosorbent assay or reverse transcription quantitative polymerase chain reaction. Also, we investigate the effects of PB203 on wrinkle formation, and the potential mechanisms underlying such effects were investigated in UVB-induced wrinkle mouse model mice.
Results:PB203 alleviated the UVB-induced reactive oxygen species production, phosphorylation of JNK, ERK, and p38, and formation of AP-1. In addition, PB203 inhibited the decreases in type I collagen and TIMP-1 levels, and the increase in MMP-1 levels in UVBexposed HaCaT cells. In UVB-induced wrinkle mouse model, PB203 inhibited the decreases in elastin and type I collagen levels as well as the increases in MMP-1 expression, wrinkle formation, and skin dehydration. Furthermore, PB203 increased the expression of filaggrin, HAS1, and HAS2, improving the skin barrier function.
Conclusion:Taken together, we found that PB203 is as a potent candidate to serve as a functional ingredient or therapeutic agent to improve UVB-mediated skin aging.
