Abstract

Delayed wound healing will result in the development of chronic wounds in some diseases, such as diabetes. Amphibian skins possess excellent wound-healing ability and represent a resource for prospective wound-healing promoting compounds. A potential wound-healing promoting peptide (CW49; amino acid sequence APFRMGICTTN) was identified from the frog skin of Odorrana grahami. It promotes wound healing in a murine model with a full-thickness dermal wound in both normal and diabetic animals. In addition to its strong angiogenic ability with respect to the upregulation of some angiogenic proteins, CW49 also showed a significant anti-inflammatory effect in diabetic wounds, which was very important for healing chronic wounds. CW49 had little effect on re-epithelialization, resulting in no significant effect on wound closure rate compared to a vehicle control. Altogether, this indicated that CW49 might accelerate diabetic wound healing by promoting angiogenesis and preventing any excessive inflammatory response. Considering its favorable traits as a small peptide that significantly promotes angiogenesis, CW49 might be an excellent candidate or template for the development of a drug for use in the treatment of diabetic wounds.
