Abstract:

The effects of Kushui rose essential oil on melanin synthesis in mouse B16 melanoma cells were investigated and its mechanism of action was explored to provide an experimental basis for the development and application of Kushui rose essential oil as a natural active substance. The volatile components of the essential oil were analyzed by gas chromatography-mass spectrometry (GC-MS). The cell model with high melanin expression induced by α-melanocyte-stimulating hormone (α-MSH) was constructed using in vitro cultured mouse B16 cells. The effects of Kushui rose essential oil on melanocyte viability were determined by CCK8 method; the changes in melanin content and tyrosinase (Tyr) activity in B16 cells were analyzed by enzyme-linked immunosorbent assay (ELISA) and dopa oxidation method, respectively; the expression of cyclic adenosine monophosphate (cAMP)-responsive element-binding protein (CRE-binding protein, CREB), p38 MAP kinase (p38 MAPK) and extracellular signal-regulated kinase (ERK) in three signaling pathways was measured. The expression of CREB, p38 MAPK, ERK and microphthalmia-associated transcription factor (MITF) in B16 cells was determined by quantitative real-time PCR (qRT-PCR) and western blotting using Kushui rose essential oil at a mass concentration of 2 g/L for 12 h, 24 h and 48 h, respectively. qRT-PCR results showed that the expression of MITF gene was significantly inhibited after 48 h treatment of B16 cells with Kushui rose essential oil. The expression of MITF gene was down-regulated by 76%, and the expression of CREB and p38 MAPK was also significantly inhibited, in which the inhibition rates reached 54% and 41%, respectively, while the expression of ERK1 and ERK2 gradually increased with time; similar results were obtained by western blot, and the trend of the expression levels of CREB and p38 MAPK was consistent with the expression level of MITF, which decreased with time, while the expression level of ERK gradually increased with time. It demonstrates that the Kushui rose essential oil reduces intracellular melanin production through three signaling pathways: cAMP/PKA, p38 MAPK and ERK/MAPK, and thus inhibit the expression of MITF.

Key words: Kushui rose essential oil, melanin content, B16 melanoma cell, signaling pathway
