Objective:To observe the effects of the extract of Corni Fructus on the mRNA expression of tyrosinase(TYR)
tyrosinase related protein-1(TRP-1) and TRP-2 in co-culture model of melanoma cells and keratinocytes. Method: Differences concentration of the extract of Corni Fructus(1.0
0.5 g·L-1) were added in co-culture model of A375 melanoma cells and HaCat keratinocytes.RT-PCR assay was used to detect the effects of the extract of Corni Fructus on the TYR
TRP-1 and TRP-2 mRNA expression in A375 melanoma cells. Result: Compared with control group
the extract of Corni Fructus(1.0
0.5 g·L-1) down-regulated mRNA expression of TYR
TRP-1 and TRP-2 in A375 melanoma cells by 36.07%
62.34%
44.69% and 24.10%
53.00%
16.11% respectively(P<0.01). Conclusion: The extract of Corni Fructus can decrease the melanogenesis by down-regulating the mRNA expression of tyrosinase and its related protein.
