摘要:

在噬菌体phi29中, 基因组DNA的包装需要由病毒基因组编码的pRNA参与, 6个pRNA分子通过由pRNA分子间相互作用形成的六聚体来启动DNA转运马达, 这个过程由ATP提供能量。RNA纳米技术将pRNA与siRNA、核酶、反义RNA等分子稳定结合, pRNA作为一种载体把它们准确运输到癌细胞和病毒感染细胞的作用靶点, 从而发挥它们各自的功能。作为一种非编码RNA, 对pRNA的深入研究将有助于我们了解生命起源问题, 并有着广阔的应用前景。

Abstract:

In the bacteriophage phi29, a virus-encoded RNA(pRNA) is required for the packaging of its genomic DNA. Six pRNAs form a hexamer through pRNA/pRNA interaction to drive the DNA translocation motor, and ATP as the energy resource. Chimeric pRNAs can steadily combine with siRNA, ribozymes and anti-sense RNA, and then be transferred into the cancer cells and viral-infected cells by RNA nanotechnology. The continued study of pRNA will help us to understand the origin of the life and explore its possible applications.
