摘要: RNA干扰(RNAi)是近年发展起来的一种阻抑基因表达的新方法,该技术通过双链RNA的介导,可以特异性地阻断或降低相应基因的表达.在肿瘤研究中,通过RNAi技术可以选择性地抑制人类肿瘤相关基因的表达,从而抑制肿瘤细胞的生长.该技术的应用为癌症的基因治疗提供了新的方法.本文综述了小干扰RNA(siRNA)、微小RNA(miRNA)的生成和作用机制以及RNAi在肿瘤研究中的应用.

Abstract: RNA interference(RNAi) is a newly developed method to negatively regulate gene expression by introduction of homologous double stranded RNA(dsRNA) to specifically act on a gene's product,resulting in the formation of null or hypomorphic phenotypes.Discovered only recently,it has been utilized very successfully to inhibit many tumor cells growth by knocking down some oncogenes expression,suggesting an enthusiastic potential for therapeutic applications.In this review,it summarizes recent views about the mechanism of small interference RNA(siRNA) and microRNA production and process,and the current and future potential in cancer diagnosis and prevention.

Key words: RNA interference, small interfering RNA, gene silencing, tumor
