RNA Modifications as Drug Targets: Unlocking the Therapeutic Potential of the Epitranscriptome.

Introduction: The epitranscriptome covers reversible changes to RNA. These changes help control gene expression by making RNA more stable, easier to use, or more prone to degradation. They are increasingly implicated in disease development and offer a promising target for treatment. This review covers RNA alterations and their potential clinical applications. Methods: The systematic analysis of the peer-reviewed literature was performed, including experimental, clinical, and computational research. The biochemical properties and biological functions were used to classify RNA modifications. In addition, we evaluated current therapeutic options, including small molecules, CRISPR/Cas-based technologies, and RNA-targeted approaches. Results: RNA undergoes immense changes, including N6-methyladenosine (m6A), 5-methylcytosine (m5C), and pseudouridine. By these modifications, the genes are regulated by coordinated writers, erasers, and readers. Targeted therapeutics aim to regulate changes in cancer, neurodegenerative disease, and viral diseases. Several limitations remain, including overly general framing, suboptimal clarity in conveying the message, and inadequate response mechanisms. Discussion: The epitranscriptome provides an additional regulatory layer with significant therapeutic applications. New techniques appear to be successful. Researchers, in turn, should be more specific. These therapies require improved delivery vehicles and reduced side effects not associated with the treatment to be safe and effective for the patient. Conclusion: Therapy targeting RNA-based modifications is a breakthrough in disease treatment. These chemical modifications affect gene function and expression patterns. The next step in the research requires overcoming current limitations to fully realize the therapeutic potential of epitranscriptomics-based interventions.
