摘要：【中文】本发明公开了一种用于细胞凋亡信号通路有效成像的DNA纳米器件的设计原理、最优条件及其成像应用。虽然许多细胞凋亡信号通路已由经典的分子生物学技术所揭示，但细胞凋亡相关研究仍然迫切需要研发具有可操作性和高效率的技术和方法。为此，我们设计了一种DNA纳米器件，它是通过在金纳米颗粒表面组装一层Y型DNA结构所构建而成。只有包含了上游的锰超氧化物歧化酶信使RNA和下游的细胞色素c的凋亡信号通路作为输入时，DNA纳米器件才能执行“与”逻辑门操作，使Y型DNA从金纳米颗粒表面去组装，输出荧光信号。与靶向单个信号分子的分析方法相比，本发明中的DNA纳米器件同时表征上下游两个相关的信号分子，可以实现对细胞凋亡的信号通路直接的原位分析。 【EN】The invention discloses a design principle, an optimal condition and an imaging application of a DNA nano device for effectively imaging an apoptosis signal path. Although many apoptotic signaling pathways have been revealed by classical molecular biology techniques, there is still an urgent need for apoptosis-related research to develop techniques and methods that are operable and highly efficient. Therefore, a DNA nano device is designed, and is constructed by assembling a layer of Y-shaped DNA structure on the surface of gold nanoparticles. Only when an apoptosis signal path containing upstream manganese superoxide dismutase messenger RNA and downstream cytochrome c is used as input, the DNA nano device can execute AND logic gate operation, so that Y-type DNA is disassembled from the surface of the gold nano particle, and a fluorescence signal is output. Compared with the analysis method of targeting a single signal molecule, the DNA nano device simultaneously represents two related signal molecules at the upstream and the downstream, and can realize the direct in-situ analysis of the signal path of apoptosis.
