含溴结构域和额外终端域家族蛋白——表观遗传领域的新型治疗靶点

Bromodomain and extraterminal proteins——a novel class of therapeutic targets in epigenetics

BET(bromodomain and extraterminal)是一类能解读表观遗传密码的蛋白,通过识别和结合乙酰化的组蛋白或非组蛋白,在调节基因转录中发挥重要的作用。BET抑制剂在肿瘤和炎症等临床前疾病模型中表现出良好的疗效,且已有部分抑制剂进入临床阶段,这表明以BET为治疗靶点的药物研发具有可观前景。本文将对BET蛋白的结构功能、BET抑制剂与疾病治疗以及其作为治疗靶点的分子机制等方面进行阐述。

Bromodomain and extraterminal（BET） proteins are a class of proteins that can interpret epigenetic codes and play an important role in regulating gene transcription through identifying and binding acetylated histones or non-histones proteins. The BET inhibitors have emerged with good therapeutic effects in preclinical disease models such as cancer and inflammation. Some of them have entered clinical studies, demonstrating that there is considerable prospect for drug development with BET as a potential therapeutic target. This review briefly describes the structures and functions of the BET proteins, the BET inhibitors in various diseases, as well as molecular mechanisms involved.
