Regulation of YY1 by SET7/9-mediated methylation [PDF]
, 2016 目前随着生活品质的改善和人类寿命的延长，许多老年疾病例如癌症成为人类常见的疾病，目前治疗癌症除了常规手段之外，一种伤害比较小的即表观遗传治疗手段逐渐被提上研究日程。 蛋白甲基化修饰系统对于基因组精密转录至关重要。蛋白甲基化酶和去甲基化酶通过对组蛋白动态修饰调控基因转录是表观遗传学“组蛋白密码子学说”的核心内容之一，其失调会导致包括癌症在内的多种疾病的发生。众所周知基因转录也受到转录因子的精密调控，然而甲基化修饰系统如何通过以转录因子为代表的非组蛋白底物调控基因转录的模式还不完全清楚 ...

The Functions and Mechanisms of Histone Demethylase JMJD1A in Urinary Bladder Cancer Development [PDF]
, 2015 JMJD1A（JumonjiCdomain-containing1A），又名JHDM2A，KDM3A，是一种组蛋白去甲基化酶，可以特异性去除H3K9位点的一甲基化和二甲基化，在组蛋白甲基化修饰中起到重要作用。JMJD1A表达受到低氧诱导因子HIF-1α（hypoxia-induciblefactor1α）的调节，并且参与到肿瘤细胞对低氧环境的适应性调节过程中。 膀胱癌是世界范围内高发和高致死率的恶性肿瘤之一。已有报道JMJD1A在膀胱癌肿瘤组织中高表达，但是JMJD1A在膀胱癌的发生发展机制尚不清楚 ...
