基于核酸的纳米器件已广泛应用于生物传感和纳米医学领域。传统上,大多数纳米器件首先使用合成 DNA 或 RNA 寡核苷酸在体外构建,然后输送到细胞中。如今,基因编码RNA纳米器件的出现为细胞内分析和调控提供了一种有前景的替代方法。这些基因编码的基于RNA的纳米器件可以在活细胞内直接转录并持续产生。在过去的十年里,各种高精度和可编程的纳米器件已经以这种方式构建出来。在这篇综述中,我们将总结这些人工基因编码 RNA 纳米器件的设计和功能的最新进展。我们将特别关注它们在调节细胞基因表达、成像、逻辑运算、结构生物学和光遗传学中的应用。我们相信这些基于 RNA 的多功能纳米器件将在不久的将来广泛用于探测和编程细胞和其他生物系统。新兴基因编码RNA纳米器件在调节细胞基因表达、成像、逻辑运算、结构生物学和光遗传学方面的最新设计和应用。
Nucleic acid-based nanodevices have been widely used in the fields of biosensing and nanomedicine. Traditionally, the majority of these nanodevices were first constructed in vitro using synthetic DNA or RNA oligonucleotides and then delivered into cells. Nowadays, the emergence of genetically encoded RNA nanodevices have provided a promising alternative approach for intracellular analysis and regulation. These genetically encoded RNA-based nanodevices can be directly transcribed and continuously produced inside living cells. A variety of highly precise and programmable nanodevices have been constructed in this way during the last decade. In this review, we will summarize the recent advances in the design and function of these artificial genetically encoded RNA nanodevices. In particular, we will focus on their applications in regulating cellular gene expression, imaging, logic operation, structural biology, and optogenetics. We believe these versatile RNA-based nanodevices will be broadly used in the near future to probe and program the cells and other biological systems. Recent design and applications of emerging genetically encoded RNA nanodevices in regulating cellular gene expression, imaging, logic operation, structural biology, and optogenetics.
