N6-Methyladenosine plays a crucial role in RNA biology, particularly in the regulation of gene expression. It is a key modification in messenger RNA (mRNA) that influences mRNA stability, translation efficiency, and splicing. This modification is essential for various cellular processes, including development, stress responses, and disease progression. In cancer research, it is studied for its role in tumorigenesis and as a potential biomarker for cancer diagnosis and prognosis. Additionally, it is investigated in the context of viral infections, where it can modulate viral RNA function and host immune responses. Its involvement in epigenetic regulation makes it a significant focus in the development of therapeutic strategies targeting RNA modifications.
