Mitochondrial CircRNA CircMT‐RNR2 Safeguards Antioxidant Defense to Support Fibroblast Functions in Wound Repair (Adv. Sci. 26/2026)

CircMT-RNR2-Mediated Wound Healing The cover illustrates mitochondrial CircMT-RNR2 RNA as a radiant golden ring binding to the PRDX3 protein, protecting fibroblasts from oxidative stress and enhancing their antioxidant defense and regenerative capacity. The background transitions from orange, representing chronic diabetic wounds, to blue as healing progresses, symbolizing CircMT-RNR2-mediated restoration of impaired wound repair.
