The present invention provides a target gene transcriptional repression inhibitor that can be designed in a sequence-specific manner, a composition containing the same, and use thereof. More specifically, the present invention provides a composition for use in inhibiting repression of gene expression by DNA methylation in a living subject, comprising pyrrole imidazole polyamide or a conjugate of pyrrole imidazole polyamide and a histone modifying enzyme inhibitor, wherein the pyrrole imidazole polyamide or the conjugate of pyrrole imidazole polyamide and a histone modifying enzyme inhibitor is designed so as to bind in a sequence-specific manner to a minor groove of promoter region DNA of the gene.
本发明提供了一种可以以序列特异性方式设计的靶基因转录抑制剂,以及包含该抑制剂的组合物和其使用方法。更具体地,本发明提供了一种用于抑制DNA甲基化引起的基因表达抑制的组合物,包括吡咯咪唑聚酰胺或吡咯咪唑聚酰胺与组蛋白修饰酶抑制剂的结合物,其中吡咯咪唑聚酰胺或吡咯咪唑聚酰胺与组蛋白修饰酶抑制剂的结合物被设计成以序列特异性方式结合到基因启动子区域DNA的小沟。
