RNA干扰是指具有同源性的双链RNA(dsRNA)能高效、特异地使靶mRNA发生降解、使基因转录后的mRNA不能表达而导致基因沉默的一种现象。肿瘤是多基因病,RNAi为肿瘤的基因治疗提供了新思路,RNAi相关技术作为一种简单、有效的代替基因敲除的手段正被应用于筛选药物靶基因、基因治疗、药物开发、功能基因组学等。现综述RNAi的干扰机制、特点及在肿瘤基因治疗等方面的应用进展。
RNA interference refers to a phenomenon that double-stranded RNA (dsRNA) with homology can efficiently and specifically degrade target mRNA and cause gene transcription after mRNA transcription can not be performed, leading to gene silencing. Tumor is a multi-gene disease, RNAi provides new ideas for the gene therapy of cancer. RNAi-related technology as a simple and effective alternative to gene knockout is being applied to screening drug target genes, gene therapy, drug development, functional genomics Learn. Are summarized RNAi interference mechanism, characteristics and application in tumor gene therapy and so on.
