最近发现的小干扰RNA(siRNA)基因沉默现象的治疗应用将取决于分子生物稳定性、特异性和递送的改进。为了解决这些问题,我们使用合成的 RNA 样高亲和力核苷酸类似物锁核酸 (LNA) 系统地修饰了 siRNA。在这里,我们表明,LNA 的掺入大大延长了 siRNA 的血清半衰期,这是治疗用途的关键要求。此外,我们提供的证据表明,LNA 与细胞内 siRNA 机制兼容,可用于减少不良的、与序列相关的脱靶效应。针对新出现的疾病 SARS 的 LNA 修饰 siRNA 在某些 RNA 基序上显示出比未修饰 siRNA 更高的效率。这项研究的结果强调了 LNA 将 siRNA 从功能基因组技术转变为治疗平台的前景。
Therapeutic application of the recently discovered small interfering RNA (siRNA) gene silencing phenomenon will be dependent on improvements in molecule bio-stability, specificity and delivery. To address these issues, we have systematically modified siRNA with the synthetic RNA-like high affinity nucleotide analogue, Locked Nucleic Acid (LNA). Here, we show that incorporation of LNA substantially enhances serum half-life of siRNA's, which is a key requirement for therapeutic use. Moreover, we provide evidence that LNA is compatible with the intracellular siRNA machinery and can be used to reduce undesired, sequence-related off-target effects. LNA-modified siRNAs targeting the emerging disease SARS, show improved efficiency over unmodified siRNA on certain RNA motifs. The results from this study emphasize LNA's promise in converting siRNA from a functional genomics technology to a therapeutic platform.
