The present invention provides methods for discovering agents that are effective in reversing epigenetic silencing by inhibiting the interaction of methyl-binding (MBD) proteins with methylated genomic DNA. Also provided are methods for reactivating silenced genes having CpG island hypermethylation along with methods for treatment and prevention of diseases, such as cancer and sickle cell anemia, by administering an agent that modulates methyl-binding domain (MBD) protein-mediated transcriptional repression, thereby increasing gene transcription to prevent or treat disease. Additionally, compounds identified by the present invention useful for treatment and prevention of diseases, such as cancer and sickle cell anemia, are provided.
本发明提供了通过抑制甲基结合(MBD)蛋白与甲基化基因组 DNA 的相互作用,发现可有效逆转表观遗传沉默的制剂的方法。本发明还提供了重新激活具有 CpG 岛超甲基化的沉默基因的方法,以及治疗和预防癌症和镰状细胞性贫血等疾病的方法,方法是施用一种调节甲基结合域(MBD)蛋白介导的转录抑制的制剂,从而增加基因转录以预防或治疗疾病。此外,还提供了本发明确定的有助于治疗和预防癌症和镰状细胞性贫血等疾病的化合物。
