Long non-coding RNAs (lncRNAs) are a class of RNA molecules that are longer than 200 nucleotides and do not code for proteins. They are involved in a wide range of biological processes, such as gene expression, cell differentiation, and development. Research in the field of lncRNAs has expanded rapidly in recent years, with scientists investigating their potential roles in various diseases, including cancer, cardiovascular disorders, and neurological conditions. lncRNAs have also been suggested as potential therapeutic targets and biomarkers for disease diagnosis and prognosis. Overall, the study of lncRNAs is helping to deepen our understanding of gene regulation and cellular functions.
