R elatively little progress has been made in developing therapies for mitochondrial diseases in modern medicine as a result of the exquisite complexity of the structural proteins and pathways associated with mitochondrial functions and our incomplete understanding of pathophysiology (1). Leber hereditary optic neuropathy (LHON), in particular, provides a unique model for understanding molecular...
