Summary
Mass spectrometry is a powerful tool for identifying and quantifying ribonucleic acid (RNA) modifications. Recent advances in methods and instrumentation enhance the study of RNA modifications and their impact on the epitranscriptome.
Area of Science:
- Biochemistry
- Molecular Biology
- Analytical Chemistry
Background:
- Ribonucleic acids (RNAs) are frequently modified chemically.
- These modifications typically increase nucleoside mass, making mass spectrometry a key detection method.
- The epitranscriptome, encompassing RNA modifications, is an area of growing research interest.
Purpose of the Study:
- To review recent advances in mass spectrometry for RNA modification analysis.
- To highlight improvements in instrumentation and data interpretation software.
- To discuss the role of mass spectrometry in understanding the epitranscriptome.
Main Methods:
- Mass spectrometry (MS) and tandem mass spectrometry (MS/MS) for RNA analysis.
- Development of novel methods for RNA modification identification and characterization.
- Advancements in software for interpreting tandem mass spectra of RNA.
Main Results:
- Current MS approaches provide qualitative and quantitative information on RNA modifications.
- Sequence-specific RNA modification analysis is increasingly feasible.

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
