Small interfering RNA (siRNA) has the potential to influence gene expression with a high degree of target gene specificity. However, the clinical application of siRNA therapeutics has proven to be less promising as evidenced by its poor intracellular uptake, instability in vivo, and nonspecific immune stimulations. Recently, we have demonstrated that single-walled carbon nanotube (SWNT)-mediated siRNA delivery can enhance the efficiency of siRNA-mediated gastrin-releasing peptide receptor (GRP-R) gene silencing by stabilizing siRNA while selectively targeting tumor tissues. Based on our recent findings, we introduce a novel technique to silence specific gene(s) in human neuroblastoma through SWNT-mediated siRNA delivery in vitro and in vivo.
小干扰RNA(siRNA)具有以高度的靶基因特异性影响基因表达的潜力。然而,siRNA疗法的临床应用已被证明前景不太乐观,其细胞内摄取不佳、体内不稳定以及非特异性免疫刺激就是明证。最近,我们已经证明,单壁碳纳米管(SWNT)介导的siRNA递送可以通过稳定siRNA同时选择性靶向肿瘤组织来提高siRNA介导的胃泌素释放肽受体(GRP-R)基因沉默的效率。基于我们最近的发现,我们引入了一种新技术,通过在体外和体内SWNT介导的siRNA递送使人类神经母细胞瘤中的特定基因沉默。
