Cancer remains one of the most threatening causes of human health impairment, and the mechanisms underlying tumorigenesis have not been completely characterized. MicroRNAs (miRNAs) are a group of endogenous, small (18∼25 nucleotides) non-coding RNAs which negatively regulate gene expressions by directly binding to the 3'-untranslated regions (3'-UTRs) of the target messenger RNAs (mRNAs). Increasing evidence has demonstrated abnormal miRNA profiles and confirmed their involvement in tumor initiation and progression. As one important member of the miR-200 family, microRNA (miR)-141 is aberrantly expressed in many human malignant tumors, participating in various cellular processes including epithelial-mesenchymal transition (EMT), proliferation, migration, invasion, and drug resistance. In the present review, we briefly describe the mechanisms underlying miR-141-mediated tumorigenesis and the possible future of miR-141 as a potential diagnostic and prognostic parameter as well as therapeutic target in clinical applications.
癌症仍然是人类健康受损的最具威胁性的原因之一,肿瘤发生的机制尚未完全明确。微小RNA(miRNA)是一类内源性的小(18∼25个核苷酸)非编码RNA,它们通过直接结合靶信使RNA(mRNA)的3'非翻译区(3'-UTR)来负调控基因表达。越来越多的证据表明miRNA谱异常,并证实它们参与肿瘤的起始和进展。作为miR-200家族的重要成员之一,微小RNA(miR)-141在许多人类恶性肿瘤中异常表达,参与包括上皮-间质转化(EMT)、增殖、迁移、侵袭和耐药性在内的各种细胞过程。在本综述中,我们简要描述了miR-141介导肿瘤发生的机制,以及miR-141作为潜在的诊断和预后参数以及临床应用中的治疗靶点的可能前景。
