microRNA

microRNA
micro·RNA (miRNA) (mi″kro-ahrґen-a) any of a number of very small (20–22 nucleotides) RNA molecules that act as negative regulators of gene expression by binding to specific segments of messenger RNA, thus interfering with translation. MicroRNAs are important in the regulation of cellular development, differentiation, proliferation, apoptosis, and stress response; abnormalities of miRNA expression are involved in the development of malignancies.
