The Potential of Targeting APE1/Ref-1 as a Therapeutic Intervention for Duchenne Muscular Dystrophy.

Antioxid Redox Signal

December 2024

Department of Medicine-Western Health, Melbourne Medical School, The University of Melbourne, Parkville, Australia.

Inflammation and oxidative stress play crucial roles in the development and progression of skeletal muscle diseases. This review aims to examine the existing evidence regarding the involvement and inhibition of APE1/Ref-1 (apurinic/apyrimidinic endonuclease 1/redox factor 1) in diseases, then extrapolate this evidence to the context of skeletal muscle and discuss the potential beneficial effects of APE1/Ref-1 inhibition in ameliorating myopathy with a particular focus on dystrophic pathology. Currently, therapeutic interventions targeting pathways, such as nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and nuclear factor erythroid 2-related factor 2 (NRF2), have shown limited efficacy in both clinical and preclinical settings.
