Abstract

Epigenetic changes have been linked to a host of disease states. Besides the physiological function of epigenetic changes in regulating cellular function, recent data indicates that key changes in epigenetic activity also play an important pathophysiologic role following neurotrauma specifically. Such manifestations occur through the activation or silencing of different genes. Histone methylation has emerged as a critical component of this process and can be selectively modulated after injury. Pre-clinical studies have resulted in key discoveries regarding specific methylation sites of interest. This focused review highlights some of these early findings and their relationship to clinical outcomes. These findings suggest areas of future investigation and discovery in the quest to develop ideal biomarkers and methods to utilize them in developing therapeutic interventions.

神经创伤的表观遗传学
表观遗传变化与一系列疾病状态有关。除了表观遗传变化在调节细胞功能方面的生理作用外,最近的数据表明,表观遗传活动的关键变化在神经创伤后也发挥着重要的病理生理作用。这些表现通过不同基因的激活或沉默而发生。组蛋白甲基化是这一过程的重要组成部分,可在损伤后进行选择性调节。临床前研究已经发现了有关特定甲基化位点的关键信息。这篇重点综述强调了其中一些早期发现及其与临床结果的关系。这些发现提出了未来调查和发现的领域,以寻求开发理想的生物标志物和利用它们开发治疗干预措施的方法。
