miRNAs以非细胞自主机制参与肿瘤微环境调节的研究进展

摘要

As an internal environment of tumor occurrence, tumor microenvironment is composed of a variety of cells and extracellular matrix, and plays a crucial role in tumor formation, transfer and resistance to drugs. The regulation of tumor microenvironment will be a potential target to control the cancer. MicroRNAs (miRNAs) are a kind of 21 to 25 nucleotides single-stranded RNA, and are mainly involved in regulating gene expression. Recently, with the suggestion of cellular auton-omous tumor inhibition mechanism, the regulation of tumor microenvironment by miRNAs has received great attention. This review summarizes recent findings on the non-cell-autonomous mechanisms of miRNAs-mediated regulation of tumor micro-environments, which provides foundations and perspective on the design of therapeutic interventions.%肿瘤微环境是肿瘤发生发展过程中所处的内环境,由多种细胞及细胞外基质组成,是肿瘤形成、转移以及耐药的关键因素.对肿瘤微环境的调控将成为治疗肿瘤的靶点之一.MicroRNAs(miRNAs)是一类21~25个核苷酸的非编码单链RNA,主要参与基因的表达调控.近年来,随着非细胞自主抑癌机制的提出,使miRNAs对肿瘤微环境的调控受到了极大关注.本文主要阐述miRNAs通过非细胞自主机制对肿瘤微环境的影响,为对肿瘤微环境的深入研究以及肿瘤治疗提供参考.
