The Role of Endothelin‐1 in Epidermal Hyperpigmentation and Signaling Mechanisms of Mitogenesis and Melanogenesis
1 Aug 1997
Abstract excerpt
The paracrine linkage of endothelins (ET) between keratinocytes and melanocytes suggested that ETs are intrinsic mediators for human melanocytes in UVB-induced pigmentation. In this study, the role of ET-1 in the epidermal hyperpigmentation was investigated in vivo and in vitro. The addition of 10 nM ET-1 induced a H-7 (10 microM) suppressible-increase in tyrosinase activity in cultured human melanocytes and was...
