Abstract:
Friedreich ataxia (FRDA) is a mitochondrial disease with neurodegeneration, hypertrophic cardiomyopathy and diabetes. FRDA is caused by reduced level of frataxine (FXN), an essential mitochondrial protein involved in iron-sulfur cluster biogenesis and mitochondrial homeostasis. Cardiac failure is the most common cause of mortality in FRDA. To date, no treatment exists for FRDA cardiomyopathy. During my PhD, we showed that an adeno-associated vector (AAV) rh10 expressing human FXN injected intravenously not only prevented the onset of the cardiac disease in a faithful FRDA cardiac mouse model, but also, when administered in animals with cardiac failure, reversed rapidly and completely cardiac remodeling and insufficiency. Our results demonstrate the capacity of defective cardiomyocytes with severe energy failure and ultrastructure disorganization to be rapidly corrected and remodeled by gene therapy. Thus, we showed that gene therapy may be a relevant therapeutical approach for FRDA.
