摘要
microRNA是一类在生物体中广泛表达的、非编码调节性小分子RNA(约22-24nt)。它们一经问世,即被发现参与多种疾病的发生。miR-17-92及其旁系同源序列就是其中之一,它们已被证实在肺、心脏及免疫系统的正常发育及肿瘤形成中均起到重要作用。本文从miR-17-92及其旁系同源序列在不同肿瘤组织中的表达及其在肿瘤发生中的分子机制,对这一基因簇与肿瘤发生的关系进行综述。
MicroRNAs(miRNAs) are a class of short regulatory non-coding RNAs(22~24 nt) widely expressed in living organisms.Shortly after their discovery,microRNAs are found to participate in the development of a variety of diseases.miR-17-92 and its paralog are one of them,recent studies have revealed their critical roles not only in the development of lung,heart,immune system but also in carcinogenesis.The present article mainly focuses on their different expression patterns and molecular mechanisms to elucidate their contribution to cancer development.
