host cells. Both antisense technology and small molecules have been used to independently inhibit endogenous miR‐122 function, but not in combination. Intracellular stability, efficient delivery, hydrophobicity, and controlled release are some of the current challenges associated with these novel therapeutic methods. Reported herein is the first single‐vehicular system, based on mesoporous silica nanoparticles
微小RNA(miRNA)调节多种生物学过程。肝脏特异性,高度丰富的miR-122与许多人类疾病(包括癌症)有关。已发现其抑制作用导致丙型肝炎病毒(HCV)感染宿主细胞的能力急剧下降。反义技术和小分子均已被用来独立抑制内源性miR-122的功能,但不能组合使用。细胞内稳定性,有效递送,疏水性和控释是与这些新型治疗方法有关的当前挑战。本文报道的是第一个基于介孔二氧化硅纳米粒子(MSN)的单车系统,用于同时细胞递送miR-122 antagomir和小分子抑制剂。
