Modulating the Wnt Signaling Pathway in Wound Healing: The Potential of L-Carnosine, Zinc Sulfate, and B-Complex Vitamins Cocktail

Background: The process of wound healing is a dynamic event that starts with inflammation, proliferation, and migration of various types of fibroblast cells and aims to restore the integrity and functionality of damaged tissue. One crucial signaling pathway involved in wound healing is the Wnt signaling pathway. This study aimed to investigate the effects of a cocktail consisting of L-carnosine, zinc sulfate, and B-complex vitamins on the modulation of the Wnt signaling pathway during wound healing. Methods: The optimal dosages of L-carnosine, zinc sulfate, and B-complex were used to prepare the cocktail. Then, the cocktail-mediated wound healing was measured through scratch assay on human dermal fibroblast (HDF) cells. Finally, the effects of the cocktail on the expression of SFRP1, SFRP2, SFRP4, MMP7, and RSPO2 genes involved in the Wnt signaling pathway were measured during the wound closure phenomenon by real-time quantitative polymerase chain reaction (RT-qPCR). Results: The scratch assay demonstrated the wound-healing effects of the prepared cocktail on HDF cells. Additionally, the RT-qPCR results showed that the cocktail can activate the Wnt signaling pathway by down-regulating the expression of SFRP1, SFRP2, SFRP4, and MMP7 and up-regulating the expression of RSPO2. Conclusions: The data suggest that the L-carnosine, zinc sulfate, and B-complex vitamin cocktail exhibits wound healing properties by increasing fibroblast proliferation via the activation of the Wnt pathway.
