与细胞结合并随后内化的核酸可能被证明是一种新的递送试剂。一种抗前列腺特异性膜抗原适配体通过模块化链亲和素桥接与sirna偶联,该适配体先前已被证明与前列腺肿瘤细胞结合。所得的偶联物可以简单地添加到细胞上,无需任何进一步的准备,并在30分钟内被吸收。sirna介导的基因表达抑制与传统的脂质试剂一样有效,并且依赖于与适体的结合。这些结果为sirna的治疗递送和可用于探测细胞生理学的试剂的开发提供了新的途径。
Nucleic acids that bind to cells and are subsequently internalized could prove to be novel delivery reagents. An anti-prostate specific membrane antigen aptamer that has previously been shown to bind to prostate tumor cells was coupled to siRNAs via a modular streptavidin bridge. The resulting conjugates could be simply added onto cells without any further preparation, and were taken up within 30 min. The siRNA-mediated inhibition of gene expression was as efficient as observed with conventional lipid-based reagents, and was dependent upon conjugation to the aptamer. These results suggest new venues for the therapeutic delivery of siRNAs and for the development of reagents that can be used to probe cellular physiology.
