Trichostatin A suppresses hearing loss by reducing oxidative stress and inflammation in an Alport syndrome model.

ABSTRACT: Alport syndrome (AS) is a genetic disorder marked by mutations in type IV collagen, leading to kidney glomerular dysfunction. AS also involves the cochlea, causing late-onset progressive hearing loss. Currently, there are no therapeutic drugs to protect hearing from AS. HDAC inhibitors (HDACis) are chemical compounds that block the activity of histone deacetylase and are known to exert diverse biologic effects. We investigated the effect of Trichostatin A (TSA), an HDACi, to assess its potential to inhibit hearing deterioration in AS. Col4a3 knockout (KO) mice were treated with TSA at 3 weeks of age, and hearing levels were measured using auditory brainstem response (ABR). The results demonstrate that TSA significantly protects the hearing of KO mice compared to the untreated group. The TS
