Alpha–lipoic acid supplementation improves pathological alterations in cellular models of Friedreich ataxia

Talaverón-Rey, M., Reche-López, D., Povea-Cabello, S. et al. Alpha–lipoic acid supplementation improves pathological alterations in cellular models of Friedreich ataxia. Orphanet J Rare Dis 20, 453 (2025).doi:10.1186/s13023-025-03990-z 

 Treatment with ALA was able to correct partially the pathological alterations in mutant fibroblasts. The optimal ALA concentration was dependent on the number of expanded GAA triplet repeats in the FXN gene. The positive effect of ALA was also confirmed in induced neurons derived from FRDA mutant fibroblasts. Our results also suggest that the positive effect of ALA was mediated by Peroxisome Proliferator-Activated Receptor Gamma activation. 

Conclusions: Our results suggest that ALA treatment can increase the expression levels of frataxin and reverse the mutant phenotype in cellular models of FRDA.
