Messenger RNA carries instructions for building proteins from our DNA to the cell’s ribosomes. Along the way, chemical tags are added to RNA, much like sticky notes added to a recipe. Although the underlying RNA remains the same, these tags can change the amount of protein created, how We see folded, and how long the RNA persists in the cell, a process known as epitranscriptomics. The EU-funded ROPES project sought to grow European capacity in this field, and explored how changes to RNA influence protein expression and health. The project has now been featured in the CORDIS series of explanatory videos titled ‘Make the connection with EU science’. “Over the course of the project, we saw our early stage researchers strengthen not only their technical skills but also their professional networks across Europe,” says project coordinator Alessandro Quattrone, from the University of Trento in Italy. “This work has helped to prepare a cohort of young scientists who can carry this field forward – an outcome we consider a major success.”
The Rising Field of Epitranscriptomics
For decades, scientists focused on the genome – the complete set of DNA instructions. More recently, the spotlight has shifted to the epigenome, which describes changes to DNA that affect gene expression without altering the DNA sequence itself. Now, epitranscriptomics is emerging as the next frontier, revealing a layer of regulation that controls RNA fate and function. These chemical modifications to RNA, often likened to “sticky notes,” are proving to be remarkably influential.
Decoding the ‘Sticky Notes’ of RNA
These RNA modifications impact several key processes. They can alter how much protein is produced from a given RNA molecule, influence how the protein folds into its functional shape, and determine how long the RNA molecule persists within the cell. Understanding these mechanisms is crucial for unraveling the complexities of disease.
Implications for Disease Detection and Treatment
The potential applications of epitranscriptomics are vast. Researchers are exploring how changes in RNA modifications contribute to various diseases, including viral infections. The ability to detect these changes could lead to earlier and more accurate diagnoses. Manipulating RNA modifications offers a novel therapeutic avenue – potentially allowing scientists to correct aberrant patterns and restore normal cellular function.
Building European Expertise
The EU-funded ROPES project, coordinated by the University of Trento in Italy, has been instrumental in fostering European expertise in epitranscriptomics. The project focused on strengthening the skills and networks of early-stage researchers across Europe, preparing them to lead future advancements in the field.
Future Trends and Opportunities
Several key trends are shaping the future of epitranscriptomics. Advances in sequencing technologies are enabling researchers to map RNA modifications with unprecedented resolution. Computational tools are being developed to analyze the vast amounts of data generated, identifying patterns and predicting functional consequences. The development of small molecules that can selectively modify RNA is also gaining momentum, offering the potential for targeted therapies.
The Convergence of Technologies
A significant trend is the convergence of epitranscriptomics with other ‘omics’ technologies – genomics, transcriptomics, proteomics, and metabolomics. Integrating data from these different layers of biological information will provide a more holistic understanding of disease processes and identify novel therapeutic targets.
