摘要
微小RNA(micro-RNA,即miRNA)是长约21-23nt的非编码短链RNA,是基因表达的转录后调节因子,通过与靶miRNA特异的碱基配对,引起靶miRNA降解或翻译抑制。近年研究表明miRNA在肿瘤的发生和发展中起着重要作用。
MicroRNA (miRNA) constitute a large family of smaU,approximately 21 to 23 nucleotide-long, non-coding RNA that is a key post-transcriptional regulators of gene expression,By base pairing to mRNA, miRNA mediate translational repression or miRNA degradation. The recent study find that miRNA play an important role in carcinogenesis. Here is a reviews of the research advances of miRNA and ovarian cancer.
