Tóm tắt

AbstractHoney has been used since ancient times for wound repair, but the subjacent mechanisms are almost unknown. We have tried to elucidate the modulatory role of honey in an in vitro model of HaCaT keratinocyte re‐epithelialization by using acacia, buckwheat, and manuka honeys. Scratch wound and migration assays showed similar increases of re‐epithelialization rates and chemoattractant effects in the presence of different types of honey (0.1%, v/v). However, the use of kinase and calcium inhibitors suggested the occurrence of different mechanisms. All honeys activated cyclin‐dependent kinase 2, focal adhesion kinase, and rasGAP SH3 binding protein 1. However, vasodilator‐stimulated phosphoprotein, integrin‐β3, cdc25C, and p42/44 mitogen activated protein kinase showed variable activation pattern. Re‐epithelialization recapitulates traits of epithelial‐mesenchymal transition (EMT) and the induction of this process was evaluated by a polymerase chain reaction array, revealing marked differences among honeys. Manuka induced few significant changes in the expression of EMT‐regulatory genes, while the other two honeys acted on a wider number of genes and partially showed a common profile of up‐ and down‐regulation. In conclusion, our findings have shown that honey‐driven wound repair goes through the activation of keratinocyte re‐epithelialization, but the ability of inducing EMT varies sensibly among honeys, according to their botanical origin.
