    摘要: Provided herein, in some aspects, is a multiplex RNA targeting system that enables live cell imaging and/or modification of multiple RNA targets. Specifically, the disclosure provides a method of live cell imaging of ribonucleic acid (RNA), or targeting RNA in a live cell, comprising: (a) delivering to a cell an RNA-editing complex that comprises a catalytically inactive Cas13 (dCas13) nuclease, a Cas 13 guide RNA (gRNA) comprising an RNA aptamer sequence, and a detectable molecule linked to an RNA-binding domain (RBD), or an RNA effector molecule linked to an RBD sequence that specifically binds to the RNA aptamer sequence; and (b) imaging the detectable molecule or RNA aptamer and RBD binding.
