Abstract
Histone deacetylase 6 (HDAC6), a distinctive member of the histone deacetylase family, plays a crucial role in regulating the cellular response to oxidative stress. Unlike other HDACs, HDAC6 primarily deacetylates non‑histone proteins, influencing various cellular functions critical to the pathogenesis of numerous oxidative stress‑related diseases. This review summarizes the latest research on how HDAC6 affects oxidative stress pathways and its impact on diseases such as neurodegeneration, cancer and cardiovascular disorders. Additionally, the therapeutic potential of targeting HDAC6, as evidenced by preclinical trials, was discussed, suggesting that HDAC6 inhibitors can ameliorate symptoms and alter disease progression in numerous disease models. By elucidating the multifaceted roles of HDAC6 in oxidative stress and disease, the review aims to underscore its potential as a therapeutic target. This review enhances the understanding of HDAC6 and presents new opportunities for innovative treatment approaches that can address oxidative stress‑related illnesses.
