Summary

In this talk, Dr. Kristin Koutmou provides an overview of the technologies used to study RNA modifications, emphasizing their importance in gene regulation and disease. She begins by explaining the historical context, noting that over 150 types of RNA modifications exist and that recent advances have revealed more than 10,000 modification sites in eukaryotic mRNAs. The talk then details three main approaches: global ribonucleotide modification profiling (GRMP) using TLC and LC-MS/MS, which offers direct and quantitative detection but lacks sequence context; sequencing-based methods that map modifications transcriptome-wide but are indirect and often not quantitative; and nanopore sequencing, which provides long-read direct RNA analysis but currently has high error rates and limited quantification. Dr. Koutmou highlights the strengths and limitations of each method, stressing that no single technology can address all questions. She concludes by advocating for the integration of multiple platforms to achieve comprehensive and functional insights, aligning with recommendations from a recent National Academies report. The Q&A session touches on prioritizing abundant modifications and the need for site-specific editing tools.
