肝细胞癌(HCC)是全世界最常见的癌症之一,也是癌症相关死亡的第三大原因。对HCC发病机制的了解不足,导致其早期诊断和治疗困难。 MicroRNA (miRNA) 是一类长度约为 22 个核苷酸的非编码单链 RNA,通过与目标信使 RNA (mRNA) 的 3' 非翻译区 (3'UTR) 碱基配对来转录后调节基因表达。在许多(如果不是全部)癌症中都发现了 miRNA 的异常表达,并且许多失调的 miRNA 已被证明通过调节各种癌基因或抑癌基因的表达在癌症的发生和进展中发挥着至关重要的作用。在本文中,我们将总结HCC中异常表达的miRNA的调控和功能,并讨论miRNA作为HCC诊断和预后生物标志物的潜在应用及其在HCC干预中的潜在作用。
Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide and the third cause of cancer-related death. Poor understanding of the mechanisms underlying the pathogenesis of HCC makes it difficult to be diagnosed and treated at early stage. MicroRNAs (miRNAs), a class of noncoding single-stranded RNAs of ~22 nucleotides in length, posttranscriptionally regulate gene expression by base pairing with the 3′ untranslated regions (3′UTRs) of target messenger RNAs (mRNAs). Aberrant expression of miRNAs is found in many if not all cancers, and many deregulated miRNAs have been proved to play crucial roles in the initiation and progression of cancers by regulating the expression of various oncogenes or tumor suppressor genes. In this Paper, we will summarize the regulations and functions of miRNAs aberrantly expressed in HCC and discuss the potential application of miRNAs as diagnostic and prognostic biomarkers of HCC and their potential roles in the intervention of HCC.
