Amphibian skin contains wound-healing peptides, antimicrobial peptides, and insulin-releasing peptides, which give their skin a strong regeneration ability to adapt to a complex and harsh living environment. In the current research, a novel wound-healing promoting peptide, PM-7, was identified from the skin secretions of , which has an amino acid sequence of FLNWRRILFLKVVR and shares no structural similarity with any peptides described before. It displays the activity of promoting wound healing in mice. Moreover, PM-7 exhibits the function of enhancing proliferation and migration in HUVEC and HSF cells by affecting the MAPK signaling pathway. Considering its favorable traits as a novel peptide that significantly promotes wound healing, PM-7 can be a potential candidate in the development of novel wound-repairing drugs.
蛙类皮肤含有多种具有促进伤口愈合、抗菌和释放胰岛素功能的肽类物质，这使它们的皮肤具有很强的再生能力，以适应复杂而恶劣的生活环境。在目前的研究中，从 皮肤分泌物中鉴定出一种新型的促进伤口愈合的肽 PM-7，其氨基酸序列为 FLNWRRILFLKVVR，与以前描述的任何肽都没有结构相似性。它在小鼠中显示出促进伤口愈合的活性。此外，PM-7 通过影响 MAPK 信号通路，表现出增强 HUVEC 和 HSF 细胞增殖和迁移的功能。鉴于其作为一种新型显著促进伤口愈合的肽的优良特性，PM-7 可能成为新型伤口修复药物开发的潜在候选药物。
