摘要
在肿瘤形成过程中,启动子区异常高甲基化的抑癌基因始终保持沉默、功能丧失,而启动子区去甲基化后抑癌基因则可以重新激活。因此,DNA去甲基化药物可治疗肿瘤。本文阐述了DNA甲基化与肿瘤的关系,以及DNA去甲基化药物的研究现状。
The promoter of exceptionally hypermethylation in tumor suppressor genes including key genes always kept silent and lost functions in the process of tumor formation.However,the tumor suppressor genes could be reactivated after the promoter region demethylation,which induce re-expression of tumor suppressor genes.Some of DNA demethylation drugs have been used in clinical treatment.The relationship between DNA methylation and tumor and the research of DNA demethylation drug is reviewed.
