RNA研究的最新进展在生物学和化学方面提出了新的指导,以揭示核糖核酸在细胞过程中的复杂作用。可视化天然RNA的创新技术,特别是活细胞中的短的、低丰度的RNA,可以极大地影响目前对生物学中RNA的研究。在这里,我们报道了一种新的方法,基于可编程的寡核苷酸探针,通过级联杂交反应(CHR)自组装,在活细胞内进行实时的microRNA成像。
Recent advances in RNA research have posed new directives in biology and chemistry to uncover the complex roles of ribonucleic acids in cellular processes. Innovative techniques to visualize native RNAs, particularly, short, low-abundance RNAs in live cells, can dramatically impact current research on the rotes of RNAs in biology. Herein, we report a novel method for real-time, microRNA imaging inside live cells based on programmable oligonucleotide probes, which self-assemble through the Cascade Hybridization Reaction (CHR).
