文题释义:
miRNA:
是一种内源性的、长度为8-25个核苷酸组成的单链非编码RNA,通过特异性结合靶基因mRNA的3’非翻译区(3’-UTR),调节基因转录后的表达,影响蛋白质合成,进而在细胞生物学行为反应(如细胞增殖、凋亡、分化、免疫应答、脂质代谢)等多个方面起到调控作用。在病理情况下外泌体分泌量增加,外泌体源miRNAs表达水平有改变。鉴于此,外泌体源miRNAs是近年探讨白血病分子发病机制以及挖掘诊治靶点的一个研究热点。
生物标记物:近年来随着免疫学和分子生物学技术的发展而提出的一类与细胞生长增殖有关的标志物。生物标记物不仅可从分子水平探讨发病机制,而且在评价早期、低水平的损害方面有着独特的优势,可提供早期预警,很大程度上为临床医生提供了辅助诊断的依据。

 

摘要
背景:
外泌体是穿梭在细胞间的物质传递与信息交流载体,是活细胞分泌到胞外的一种膜包被的纳米级囊泡。外泌体携载有亲本细胞来源的核酸(DNA、mRNA、microRNA等)、蛋白质、脂质等生物大分子,经体液流动远距离调控靶细胞的功能。白血病是一类造血系统的恶性肿瘤,大部分患者难以治愈。已有研究表明,外泌体源miRNA受脂质保护不易被RNase水解,介导白血病细胞的浸润、转移等恶性生物学行为。
目的:对外泌体源miRNA在白血病中的作用进行综述,为探索白血病的分子发病机制以及挖掘诊治靶点提供重要信息。
方法:以“外泌体、白血病、miRNAs”为中文检索词,以“Exosome,Leukemia,miRNAs”为英文检索词,通过计算机检索PubMed数据库与万方医学网;检索时限:2003年11月至2018年5月,最终纳入48篇文献进行结果分析。
结果与结论:外泌体源miRNA通过驯化造血微环境,使白血病细胞的存活、增殖和迁移浸润等恶性生物学行为得到加强。通过干预外泌体源miRNA的产生和释放,阻断受体细胞摄取外泌体源miRNA以及干涉其调控的靶基因等可能会拓展白血病的治疗理念。通过深入探讨外泌体源miRNA在白血病中的作用,为挖掘诊治靶点提供重要信息。

Abstract:

BACKGROUND: Exosomes, known as vehicles for substance transporting and signaling communication, are nanosized bilayer-lipid membrane microvesicles secreted by living cell types that harbor biological constituents such as nucleic acids (DNA, mRNA and microRNA) proteins and lipids derived from host cells, which can potentially transfer their cargo through the extracellular fluid to the other cells at distance. Leukemia is a deadly hematologic malignancy. Recent studies have demonstrated that exosomal miRNAs protected from enzymatic degradation (RNase) by the lipid-bilayer membrane are associated with the invasion as well as metastasis in leukemia. 
OBJECTIVE: To review the role of exosomal miRNA in leukemia, providing important information on exploring the molecular pathogenesis and targets for diagnosis and treatment of leukemia. 
METHODS: PubMed and WanFang databases were retrieved for articles concerning leukemia and exosomal miRNA published from November 2003 to May 2018.The key words were “exosomes, leukemia, miRNAs” in English and Chinese, respectively. Forty-eight eligible articles were included in final analysis.
RESULTS AND CONCLUSION: Exogenous miRNAs enhance the malignant biological behaviors such as survival, proliferation and migration of leukemia cells by acclimating the hematopoietic microenvironment. We can extend the concept of treating leukemia by interfering with the production and release of exogenous miRNAs, blocking the uptake of exogenous miRNAs by the recipient cells and interfering with their target genes. In-depth study on the role of exogenous miRNAs in leukemia is helpful to provide important information for mining diagnostic and therapeutic targets.
