Identification and Quantification of Intracellular N-acetylglucosamine Modified GlycoRNAs
Researchers from Nanjing University have developed a novel general paradigm for the identification and quantification of intracellular N-acetylglucosamine (GlcNAc) modified glycoRNAs, published in Nature Communications. The study addresses the urgent need to understand the components and distributions of these recently discovered glycoconjugates. By integrating metabolic labeling technology with designed fluorescent DNA probes, the team utilized fluorescence resonance energy transfer imaging to identify GlcNAc-modified Y5 RNA, locating it primarily within the cell nucleus. Following target-specific capture, the researchers employed gel electrophoresis and mass spectrometric analysis to determine the specific components of GlcNAc-conjugated ribonucleotides. Furthermore, they achieved in situ quantification of intracellular GlcNAc-modified Y5 RNA levels across different cell lines using a GlcNAc-specific in situ hybridization-mediated proximity ligation assay. This method offers single-cell and single-molecule resolution. These findings provide critical new information regarding the distribution and quantitation of glycoRNAs, significantly advancing the functional research potential of these molecules in glycobiology and RNA studies.
