MicroRNAs (miRNAs) are small, non-coding RNA molecules typically about 20-22 nucleotides in length that play a crucial role in the regulation of gene expression. They function by binding to complementary sequences on messenger RNA (mRNA) molecules, leading to mRNA degradation or the inhibition of its translation into proteins. This post-transcriptional regulation allows miRNAs to control a wide range of biological processes, including development, differentiation, proliferation, and apoptosis. Since their discovery in the early 2000s, miRNAs have been found to be involved in numerous physiological and pathological conditions, including cancer, cardiovascular diseases, and neurological disorders. The study of miRNAs is a rapidly growing field in molecular biology, with significant implications for understanding disease mechanisms and developing new therapeutic strategies.
