When the skin is damaged, accelerating the repair of skin trauma and promoting the recovery of tissue function are crucial considerations in clinical treatment. Previously, we isolated and identified an active peptide (livisin) from the skin secretion of the frog Odorrana livida. Livisin exhibited strong protease inhibitory activity, water solubility, and stability, yet its wound-healing properties have not yet been studied. In this study, we assessed the impact of livisin on wound healing and investigated the underlying mechanism contributing to its effect. Our findings revealed livisin effectively stimulated the migration of keratinocytes, with the underlying mechanisms involved the activation of CaSR as a peptide calcium mimetic. This activation resulted in the stimulation of the CaSR/E-cadherin/EGFR/ERK signaling pathways. Moreover, the therapeutic effects of livisin were partially reduced by blocking the CaSR/E-cadherin/EGFR/ERK signaling pathway. The interaction between livisin and CaSR was further investigated by molecular docking. Additionally, studies using a mouse full-thickness wound model demonstrated livisin could accelerate skin wound healing by promoting re-epithelialization and collagen deposition. In conclusion, our study provides experimental evidence supporting the use of livisin in skin wound healing, highlighting its potential as an effective therapeutic option. |
