RNA modification is a growing field of research that focuses on the post-transcriptional chemical modifications that occur on RNA molecules. These modifications can alter the structure, stability, and function of RNA, and play crucial roles in gene expression regulation, RNA processing, and the cellular response to various stimuli. RNA modifications can occur on various nucleotides within an RNA molecule, including adenosine, cytosine, guanosine, and uridine. Some common RNA modifications include methylation, pseudouridylation, acetylation, and ribose methylation. These modifications can impact processes such as RNA splicing, translation, and degradation, ultimately influencing gene expression and cellular function. Researchers are actively studying RNA modifications to understand their roles in normal cellular processes, as well as their potential involvement in diseases such as cancer, neurological disorders, and metabolic diseases. The field of RNA modification is rapidly expanding, with new technologies and techniques being developed to accurately detect and study these modifications in various biological contexts.
