| 摘 要： | 表观遗传调控在基因表达、DNA复制、修复和重组等重要过程中起着关键作用，表观遗传调控异常会引发多种疾病尤其是癌症。SNF5是SWI-SNF染色体重塑复合物的核心成分之一，具有强效抑癌作用。果蝇zeste基因增强子同源物2（EZH2）是目前与肿瘤关联密切且复杂的组蛋白甲基化酶，具有促癌功能。已有研究报道了表观遗传调控因子SNF5和EZH2在不同肿瘤发生发展中的作用及二者之间的相互关系。

| Abstract: | EpigeneticsreferstoheritablealterationsingeneexpressionthatdonotinvolvetheDNA coding sequence itself.Epigenetic regulation plays an important role in gene expression,DNA replication,rep-aration and reconstitution. Thus, the abnormity of epigenetic regulation may lead to different diseases, especially cancer.SNF5 ,which can suppress tumor significantly,is one of the core components of SWI/SNF chromosome remodeling complexes.EZH2,a histone methyltransferase,is closely and complicatedly related to cancer and has significant effect on tumorigenesis.There are many studies reporting the effects of epigenetic regulation factors-SNF5 and EZH2 on different tumors as well as the interrelation at present.In the present paper,the advances in the research on these two epigenetic regulation factors in the carcinogenesis are reviewed. |
