Epigenetic modifications, including DNA methylation, histone modifications, RNA epigenetics and nucleosome remodeling, are important for gene transcription, but such modifications do not change the coding sequence of the gene. Although these events are heritable, they are potentially reversible, thus opening up opportunities for the therapy of cancer. So epigenetic modifications have been thrusted into the forefront of new drug discoveries. Current knowledge suggests that the agents that intervene epigenetics by "turning back on" silenced genes may represent a significant advancement in treating many forms of cancer. In this review, we summarized the research progress of epigenetic gene regulation and the proteins which could read epigenetic codes. And the relationship between epigenetics and cancer was discussed comprehensively.
表观遗传修饰,包括DNA甲基化、组蛋白修饰、RNA表观遗传学和核小体重塑,对于基因转录很重要,但这些修饰不会改变基因的编码序列。尽管这些事件是可遗传的,但它们可能是可逆的,从而为癌症治疗带来了机会。因此,表观遗传修饰已被推到新药发现的前沿。目前的知识表明,通过“重新开启”沉默基因来干预表观遗传学的药物可能代表了治疗多种癌症形式的重大进展。在这篇综述中,我们总结了表观遗传基因调控和能够解读表观遗传密码的蛋白质的研究进展。并全面讨论了表观遗传学与癌症之间的关系。
