BigField GEG Tech's insight:
For first time, scientists use CRISPR-Cas9 to target RNA in live cells. They show that nuclear-localized RNA-targeting Cas9 (RCas9) is exported to the cytoplasm only in the presence of sgRNAs targeting mRNA and observe accumulation ofACTB, CCNA2, and TFRC mRNAs in RNA granules that correlate with fluorescence in situ hybridization. They also demonstrate time-resolved measurements of ACTB mRNA trafficking to stress granules. Their results establish RCas9 as a means to track RNA in living cells in a programmable manner without genetically encoded tags.
