【摘要】 组蛋白乙酰化是表观遗传调控的主要机制之一,由组蛋白乙酰转移酶(histone
acetyltransferases,HATs)和组蛋白去乙酰化酶(histone deacetylases,HDACs)共同调控。近年研究发现,HDACs 通过调节错误折叠蛋白的异常积聚、线粒体功能、氧化应激等,与帕金森病(Parkinson’s disease,PD)、阿尔茨海默病(Alzheimer’s disease,AD)、亨廷顿病(Huntington’s disease,HD)等多种神经退行性疾病(neurodegenerative diseases,NDs)的发病机制密切相关。在 NDs 中,组蛋白乙酰化稳态被破坏,向低乙酰化方向转移。越来越多的研究提出了组蛋白去乙酰化酶抑制剂(histone deacetylase inhibitor,HDACi)可用于治疗某些神经退行性疾病的可能性。本文对 HADCs 在 NDs 发病机制中的研究进展进行综述。

【Abstract】 Histone acetylation is one of the main mechanisms of epigenetic regulation,co-regulated by histone acetyltransferases(HATs)and histone deacetylases(HDACs). HDACs can deacetylate lysine residues of histones and non-histone proteins,regulating almost all biological processes in cells. Many experimental models have confirmed that HDACs are closely related with the pathogenesis of neurodegenerative diseases(NDs)through regulation for deposition of aggregate-prone proteins,mitochondrial function,oxidative stress,etc. In NDs,histone acetylation homeostasis is disrupted,shifting towards hypoacetylation. Recently,a growing number of studies have raised the possibility that histone deacetylase inhibitor(HDACi)could be used to treat some DAs. In this review,we discuss the latest research progress on the comprehensive role of HDACs in pathogenesis of NDs and the possible therapeutic target for treating some NDs.
