Single-Molecule RNA Mapping May Reveal How Shape Shifts Steer Health and Disease
Researchers at Singapore’s A*STAR Genome Institute have unveiled “sm‑PORE‑cupine,” a technique that combines chemical labeling with nanopore direct RNA sequencing to map RNA structures at single‑molecule resolution. The approach tags non‑paired bases, enabling full‑length reads that expose how individual transcripts from the same gene adopt distinct folds. Experiments showed that these structural variations correlate with protein synthesis efficiency and RNA degradation rates. The technology also uncovers RNA‑shape influences on viral genomes, opening new avenues for antiviral drug discovery and precision medicine.
