摘要: RNA干扰作为转录后基因沉默的有效途径,在基因调控、功能分析及疾病防治等领域发挥重要作用。小干扰RNA表达载体的诞生实现了RNA干扰技术持续、稳定和可控性应用,是实现基因沉默的理想选择。目前干扰性小RNA表达载体虽已发展到第二代,也开发出多种商品化的产品,但依然未能很好地解决其高效、安全、可控性方面的矛盾,发展陷入了瓶颈期。因此,从载体自身角度出发,通过系统分析其功能部件的特点,纵观小RNA载体的历史渊源、发展现状、存在问题和发展方向等问题,为干扰性小RNA表达载体的优化与选择提供相关理论指导。

Abstract: RNA interference as a potent gene silencing approach plays important parts in gene regulation, functional study and gene therapy. The small interfering RNA expression vector achieves a sustainable, stable and controllable application of the RNAi technology, and becomes a promising way for gene silencing. Although the interfering RNA expression vector has progressed to the second generation, and many commercial products were availabe, the discrepancies among efficiency, safety and controllability of these vectors still exist. The development of the interfering RNA expression vector seems get into a lag phase. Therefore, this article analysed the history and development of these small interference RNA expression vectors on the basis of their functional blocks, providing a theoretical fundation for the vector’s optimization and selection.
