Ginsenosides of are used to enhance skin health and beauty. The present study aimed to investigate the potential use of ginsenoside Rf (Rf) from as a new anti-pigmentation agent.
The anti-melanogenic effects of Rf were explored. The transcriptional activity of the cyclic adenosine monophosphate (cAMP) response element binding protein (CREB) and the expression levels of tyrosinase, microphthalmia-associated transcription factor (MITF), and tyrosinase-related proteins (Tyrps) were evaluated in melanocytes and UV-irradiated human skin.
Rf significantly inhibited Forskolin (FSK) or UV-stimulated melanogenesis. Consistently, cellular tyrosinase activity and levels of MITF, tyrosinase, and Tyrps were downregulated. Furthermore, Rf suppressed MITF promoter activity, which was stimulated by FSK or CREB-regulated transcription coactivator 3 (CRTC3) overexpression. Increased CREB phosphorylation and protein kinase A (PKA) activity induced by FSK were also mitigated in the presence of Rf.
Rf can be used as a reliable anti-pigmentation agent, which has a scientifically confirmed and reproducible action mechanism, via inhibition of CREB/MITF pathway.
人参皂苷用于促进皮肤健康与美丽。本研究旨在探讨人参皂苷Rf作为一种新型抗色素沉着剂的潜在用途。
探究Rf的抗黑色素生成作用。在黑素细胞和紫外线照射的人皮肤中评估环磷酸腺苷(cAMP)反应元件结合蛋白(CREB)的转录活性以及酪氨酸酶、小眼畸形相关转录因子(MITF)和酪氨酸酶相关蛋白(Tyrps)的表达水平。
Rf显著抑制福斯高林(FSK)或紫外线刺激的黑色素生成。相应地,细胞酪氨酸酶活性以及MITF、酪氨酸酶和Tyrps的水平均下调。此外,Rf抑制了由FSK或CREB调节的转录共激活因子3(CRTC3)过表达所刺激的MITF启动子活性。在存在Rf的情况下,FSK诱导的CREB磷酸化增加和蛋白激酶A(PKA)活性也得到缓解。
Rf可作为一种可靠的抗色素沉着剂,通过抑制CREB/MITF途径具有科学证实且可重复的作用机制。
