小干扰RNA(Small-interfering RNA,siRNA)是一种强有力的研究工具,也是一种很有前途的调控疾病相关基因表达的治疗平台。恶性肿瘤是基于核酸的治疗的有吸引力的疾病靶标。已经在动物模型中以及在某些情况下在人类中评估了针对致癌基因和驱动转移或血管生成的基因的siRNA。这些研究的结果表明,药物输送是一个重要的限制因素。这篇综述提供了在体内验证的基于纳米颗粒的siRNA递送系统的前景。脂质体以及聚合物和无机制剂的最新进展的结果表明,需要在体循环、肿瘤间质空间、质膜和内体中相互优化性能的属性。总结了有利于siRNA有效递送的理化性质,并讨论了未来的研究方向。
Small-interfering RNA (siRNA) is both a powerful tool in research and a promising therapeutic platform to modulate expression of disease-related genes. Malignant tumors are attractive disease targets for nucleic acid-based therapies. siRNA directed against oncogenes, and genes driving metastases or angiogenesis have been evaluated in animal models and in some cases, in humans. The outcomes of these studies indicate that drug delivery is a significant limiting factor. This review provides perspectives on in vivo validated nanoparticle-based siRNA delivery systems. Results of recent advances in liposomes and polymeric and inorganic formulations illustrate the need for mutually optimized attributes for performance in systemic circulation, tumor interstitial space, plasma membrane, and endosomes. Physiochemical properties conducive to efficient siRNA delivery are summarized and directions for future research are discussed.
