Abstract: microRNAs (miRNAs or miRs) are endogenous non-coding RNAs that negatively regulate gene expression by binding to the 3' non-coding regions of target mRNAs, resulting in their cleavage or blocking their translation. miRNAs may have an impact on cell differentiation, proliferation, and survival, and their deregulation can be inclined to diseases and cancers, including thyroid tumors. The purpose of this review is to summarize the existing findings of deregulated miRNAs in different types of thyroid tumors and to exhibit their potential target genes, especially to demonstrate those involved in tumor invasion and metastasis. In addition, new findings of circulating miRNA expression profiles, single nucleotide polymorphism (SNP) in thyroid tumors, and the correlation of somatic mutations with deregulated miRNA expression in thyroid tumors were all included in this review.

甲状腺肿瘤中microRNA表达失调的研究进展

研究目的：MicroRNAs（miRNAs或miRs）是一种内源性非编码RNA，通过与信使RNA（mRNA）的3'非编码区结合，引起mRNA的断裂或蛋白质翻译的阻断，进而对基因表达进行负性调控。miRNAs可影响细胞的分化、增殖和生存等过程，其表达失调有引起疾病甚至肿瘤的可能。miRNA表达失调已在多种人类肿瘤中出现，包括甲状腺肿瘤。本文对不同类型的甲状腺肿瘤中出现的miRNAs表达失调及miRNAs可能的下游靶基因进行综述，为甲状腺肿瘤的临床诊断及治疗提供依据。
创新要点：已有大量关于滤泡细胞起源，尤其是乳头状甲状腺癌（PTC）中miRNAs表达失调的综述，但对C细胞起源的甲状腺髓样癌（MTC）中miRNAs表达失调的研究并未形成系统。同时，在此之前没有关于各型甲状腺肿瘤miRNAs表达与其靶基因的综述报道。在这篇综述中，我们还列入了对甲状腺肿瘤患者外周循环血液中miRNAs表达谱的最新研究以及单核苷酸多态性（SNP）对甲状腺肿瘤的影响。
重要结论：总结了miRNAs在各型甲状腺肿瘤中的表达谱（见表1、3、4、6）；描述了在各型甲状腺肿瘤中不同miRNAs潜在的靶基因及其在肿瘤发生、发展、浸润、转移等多方面的作用（见图1；表2、5）。
