HDAC3 negatively regulates spatial memory in a mouse model of Alzheimer's disease.

ABSTRACT: The accumulation and deposition of beta-amyloid (Aβ) is a key neuropathological hallmark of Alzheimer's disease (AD). Histone deacetylases (HDACs) are promising therapeutic targets for the treatment of AD, while the specific HDAC isoforms associated with cognitive improvement are poorly understood. In this study, we investigate the role of HDAC3 in the pathogenesis of AD. Nuclear HDAC3 is significantly increased in the hippocampus of 6- and 9-month-old APPswe/PS1dE9 (APP/PS1) mice compared with that in age-matched wild-type C57BL/6 (B6) mice. Lentivirus -mediated inhibition or overexpression of HDAC3 was used in the hippocampus of APP/PS1 mice to investigate the role of HDAC3 in spatial memory, amyloid burden, dendritic spine density, glial activation and tau phosphorylation. Inhibition of
