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.
