摘要： Double-stranded RNA (dsRNA) induces sequence-specific post-transcriptional gene silencing in many organisms by a process known as RNA interference (RNAi). Using a Drosophila in vitro system, we demonstrate that 19-23 nt short RNA fragments are the sequence-specific mediators of RNAi. The short interfering RNAs (siRNAs) are generated by an RNase III-like processing reaction from long dsRNA. Chemically synthesized siRNA duplexes with overhanging 3' ends mediate efficient target RNA cleavage in the lysate, and the cleavage site is located near the center of the region spanned by the guiding siRNA. Furthermore, we provide evidence that the direction of dsRNA processing determines whether sense or antisense target RNA can be cleaved by the produced siRNP complex.

摘要翻译： 双链RNA（dsRNA）通过称为RNA干扰（RNAi）的过程在许多生物体中诱导序列特异性转录后基因沉默。 使用果蝇体外系统，我们证明19-23 nt短的RNA片段是RNAi的序列特异性介质。 短干扰RNA（siRNA）由来自长dsRNA的RNase III样加工反应产生。 具有突出3'末端的化学合成的siRNA双链体在裂解物中介导有效靶RNA裂解，并且裂解位点位于导向siRNA跨越的区域的中心附近。 此外，我们提供的证据表明，dsRNA加工的方向决定了正义或反义目标RNA是否可以被产生的siRNP复合物切割。
