Growing evidence has begun to elucidate the contribution of epigenetic mechanisms in the modulation and maintenance of gene expression and behavior. Histone acetylation is one such epigenetic mechanism, which has been shown to profoundly alter gene expression and behaviors. In this review, we begin with an overview of the major epigenetic mechanisms including histones acetylation. We next focus on recent evidence about the influence of environmental stimuli on various motivated behaviors through histone acetylation and highlight how histone deacetylase inhibitors can correct some of the pathologies linked to motivated behaviors including substance abuse, feeding and social attachments. Particularly, we emphasize that the effects of histone deacetylase inhibitors on motivated behaviors are time and context-dependent.

组蛋白脱乙酰基酶抑制剂对后代行为的表观遗传调控。

越来越多的证据开始阐明表观遗传机制在调节和维持基因表达和行为中的作用。组蛋白乙酰化是一种这样的表观遗传机制，已被证明可深刻改变基因表达和行为。在这篇综述中，我们首先概述了主要的表观遗传机制，包括组蛋白乙酰化。接下来，我们将重点关注有关环境刺激通过组蛋白乙酰化对各种动机行为的影响的最新证据，并强调组蛋白脱乙酰基酶抑制剂如何纠正与动机行为有关的某些病理，包括物质滥用，进食和社交依恋。特别地，我们强调组蛋白脱乙酰基酶抑制剂对动机行为的影响是时间和上下文相关的。
