聚酰胺抑制基因转录研究进展

Suppression of Gene Transcription by Polyamide——Review

聚酰胺(polyamide)是一类人工合成的小分子,能以序列特异性与DNA小沟结合,从而干扰天然转录因子与特定DNA序列的结合,实现对特定基因表达的调控。此类小分子发展迅速,近年来与烷化剂连接而提出了基因沉默新途径,具有特异基因治疗的潜力。本文总结了聚酰胺对特定基因转录抑制的研究进展。

Polyamide is a synthetic small molecule that recognizes predetermined sequences in the minor groove of DNA with affinities and specificities compared to those of DNA-binding proteins. Polyamide can suppress gene transcription by interfering with the attachment of natural transcription factors and DNA. The alkylating polyamides represent a novel approach for sequence-specific gene silencing , which might be applied to gene therapy. The research on suppression of gene transcription by polyamide was reviewed in this paper.
