表观遗传机制-包括DNA甲基化,组蛋白翻译后修饰和核小体定位的变化-调节几乎所有组织(包括大脑)的基因表达,细胞分化和发育。在成年期,表观基因组的变化对学习和记忆等高级认知功能至关重要。惊人的新证据表明,神经退行性疾病和疾病的表观遗传机制失调。虽然这些疾病的根本原因和病理生理学不同,但许多涉及限制性元件1沉默转录因子(REST)的失调,其通过表观遗传机制调节基因表达。虽然不是体细胞遗传的,但神经元中的表观遗传修饰是动态的和可逆的,这使得它们成为治疗干预的良好靶点。
Epigenetic mechanisms — including DNA methylation, histone post-translational modifications and changes in nucleosome positioning — regulate gene expression, cellular differentiation and development in almost all tissues, including the brain. In adulthood, changes in the epigenome are crucial for higher cognitive functions such as learning and memory. Striking new evidence implicates the dysregulation of epigenetic mechanisms in neurodegenerative disorders and diseases. Although these disorders differ in their underlying causes and pathophysiologies, many involve the dysregulation of restrictive element 1-silencing transcription factor (REST), which acts via epigenetic mechanisms to regulate gene expression. Although not somatically heritable, epigenetic modifications in neurons are dynamic and reversible, which makes them good targets for therapeutic intervention.
