背景说明:ACTH (4-11) 是一种促肾上腺皮质激素片段,仅在高浓度 (100 和 1000 nM) 时才具有弱的 α-黑素细胞刺激激素 (α-MSH) 效力。ACTH (4-11), an adrenocorticotropin hormone fragment, possesses a weak α-melanocyte stimulating hormone (α-MSH) potency only at high doses (100 and 1000 nM). In Vitro:α-melanocyte stimulating hormone (MSH) induces the differentiation of mouse epidermal melanocytes in vivo and in vitro. Adrenocorticotropic hormone (ACTH) possesses the same amino acid sequence as MSH does. α-MSH induces the differentiation of mouse epidermal melanocytes in vivo and in vitro. ACTH (4-11) loses almost all activity for the binding to melanocortin receptor 1 (MC1R). 参考文献:[1] Hirobe T, et al.
