Excessive melanin synthesis is one of the major troubles in the cosmetics industry, thus such research has been extensively described. Here, we investigated the anti\u2010melanogenic effects and molecular mechanisms of two types of alfalfa extracts: alfalfa ethanol precipitate (AEP) and alfalfa ethanol supernatant (AES).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The chemical composition of AEP and AES was analysed using HPAEC\u2010PAD and LC\u2013MS\/MS. B16F10 cells and MNT\u20101 cells were used to demonstrate the inhibitory effect of two alfalfa seed extracts on melanin synthesis. The gene expression and protein levels of tyrosinase, tyrosinase\u2010related protein 1 (TRP1), DCT and microphthalmia\u2010associated factor (MITF) were confirmed using semi\u2010quantitative RT\u2010PCR, western blot and immunocytochemistry. Furthermore, the underlying mechanisms of these factors were elucidated in B16F10. The inhibitory effect on melanogenesis was validated using 3D artificial skin (MelanoDerm).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Both AEP and AES reduced melanin content in B16F10 cells stimulated with \u03b1\u2010melanocyte\u2010stimulating hormone (\u03b1\u2010MSH) and subsequently decreased mRNA and protein levels of the melanogenesis\u2010related targets, tyrosinase, TRP1 and MITF, as shown by semi\u2010quantitative RT\u2010PCR and immunocytochemistry. In addition, AEP and AES reduced protein levels of the MITF upstream regulators such as extracellular signal\u2010mitogen\u2010activated protein kinases (ERK), cAMP response element\u2010binding protein (CREB) and \u03b2\u2010catenin. Similar inhibition of melanin production and decreased expression of tyrosinase protein and MITF mRNA and protein were also confirmed in MNT\u20101 human melanoma cells. Using artificial human skin tissue (MelanoDerm), a significant reduction in melanin content was observed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Alfalfa seed extracts exert an inhibitory effect on the melanin production process by modulating the activity of ERK, CREB and \u03b2\u2010catenin, thereby suppressing MITF and reducing the levels of tyrosinase, TRP1 and DCT. Collectively, these findings suggest that alfalfa extracts may be a promising avenue for further research and development in the fields of cosmetics and pharmaceuticals.<\/jats:p>\n
