Reduced mitophagy in the cochlea of aged C57BL/6J mice

An increase in mitochondrial damage has been associated with a decline in the ability to mitigate damage through mitophagy in age-related pathologies. The present study aimed to investigate the changes of mitophagy in a mouse model with age-related hearing loss. C57BL/6J mice were divided into two groups: young (1 month) and aged (12 months). Hearing tests were conducted through the measurement of auditory brainstem response (ABR). Mitochondrial...
