摘要
DNA甲基化和组蛋白修饰等表观遗传机制是恶性肿瘤发生发展的重要原因之一.然而近年来研究发现,microRNA表达水平改变也参与恶性肿瘤的形成.最新研究资料揭示,表观遗传可调控microRNA表达,而一些种类的microRNA也可调节表观遗传,并且二者之间相互作用可调控组织细胞内基因表达以及诱导体内恶性肿瘤产生.研究资料还显示,表观遗传主要通过DNA甲基化、组蛋白修饰等方式调控microRNA表达,而microRNA则通过调节DNA甲基化转移酶、维持细胞中DNA甲基化水平或改变组蛋白修饰等途径调控表观遗传.对microRNA与表观遗传之间的调控关系以及在抗肿瘤领域内的应用进行全面而系统的论述.
