Histone deacetylases in hearing loss: Current perspectives for therapy

Area of Science:

• Otolaryngology
• Molecular Biology
• Genetics

Background:

• Hearing loss is a prevalent health issue in industrialized nations.
• The precise pathogenesis and molecular mechanisms underlying hearing loss remain largely unknown.
• Histone deacetylases (HDACs) are crucial enzymes involved in numerous cellular processes, including chromatin remodeling and gene regulation.

Purpose of the Study:

• To review and summarize existing literature on the role of HDACs in hearing loss.
• To discuss the differential involvement of HDAC family members in the development of hearing loss.
• To explore the potential of pharmacological interventions targeting HDACs for hearing loss treatment.

Main Methods:

• Comprehensive literature search on HDACs and hearing loss.
• Analysis of studies investigating HDACs' association with inner ear physiology and pathology.
• Synthesis of findings regarding HDAC dysfunction, oxidative stress, and aging in the inner ear.

Main Results:

• Recent studies suggest a significant association between HDACs and the development/progression of hearing loss.
• HDAC dysfunction may contribute to oxidative stress and aging processes within the inner ear.
• Different HDAC family members exhibit varied roles in disease development.

Conclusions:

• HDACs represent a critical molecular target for understanding and treating hearing loss.
• Pharmacological modulation of HDACs presents a novel therapeutic avenue for hearing loss.
• Further research into specific HDACs could lead to targeted and effective treatments for hearing impairment.
