Advanced Science, EarlyView.D‐galactose (D‐gal) induced inner ear hair cell senescence by inhibiting TFEB transcription. RONIN/HCF1 promotes TFEB transcription to prevent cochlear HCs from D‐gal‐induced senescence through autophagy activation. Abstract Age‐related hearing loss is characterized by senescent inner ear hair cells (HCs) and reduced autophagy.
