Therapeutic potential of mitochondrial transfer in reversing mutant-to-wild-type mtDNA ratio and improving mitochondrial dysfunction in 1555A>G mtDNA mutation-associated hearing loss.

Abstract excerpt

Mitochondrial DNA (mtDNA) mutations are a major cause of sensorineural hearing loss (SNHL). The m.1555A >G mutation in the mitochondrial 12S rRNA gene is closely linked to nonsyndromic and aminoglycoside-induced hearing loss, leading to impaired oxidative phosphorylation (OXPHOS) and ATP production. Current treatments focus on auditory rehabilitation without addressing mitochondrial pathology. This study...
