Popis: Ferroptosis, a newly discovered form of cell death, can accumulation activates lipid peroxidation and excessive oxidative stress in a high glucose environment. These phenomena suggest there may be ferroptosis pathways in the pathological processes associated with diabetic ulcer (DU). Platelet-rich plasma (PRP) promotes the healing of DU wounds, which may be achieved by the regulation of ferroptosis pathways. Hence, the present study aimed to investigate this association and uncover the potential underlying mechanisms.Cell injury models induced by high glucose were constructed using EA.HY926 (vascular endothelial cells), HSF (fibroblasts), and rat DU models. The MDA, total ROS, total SOD content, the gene and protein expression ofThe results show that compared with the DU control group, the healing rate of the dorsal ulcer wound in the PRP intervention group was accelerated, and the expression levels of inflammatory cytokines IL-1β, IL-10, andIn this study, ferroptosis was preliminarily verified in DUs at the cellular and animal levels, while PRP could inhibit ferroptosis and significantly improve the migration and regeneration ability of fibroblasts and vascular endothelial cells induced by high glucose.
