多形性胶质母细胞瘤(GBM)是一种无法治愈的脑癌,预后非常差。由于其高度侵袭性,在手术切除过程中不可能去除所有肿瘤细胞,因此复发不可避免。因此,有必要进一步研究GBM发病机制的调控机制,在过去的十年中,人们越来越关注microRNA(miRNA)的功能作用。这项系统性综述旨在全面概述有关GBM中miRNA表达谱和功能的所有可用文献。在这里,我们回顾了163篇论文,并确定了253个上调,95个下调,17个有争议的miRNA的表达水平;这些miRNA的85%尚未进行功能表征。本研究的重点是26个参与间充质迁移和侵袭模式的有趣miRNA,证明了miRNA在细胞生态位背景下的重要性。致癌和肿瘤抑制miRNAs都被发现影响参与细胞迁移、细胞骨架重排、侵袭性和血管生成的靶基因。显然,这些miRNAs的独特功能特性需要进一步研究,并可能在未来靶向GBM的分子治疗中具有巨大潜力。本文的在线版本(doi:10.1007/s12035-012-8349-7)包含补充材料,可供授权用户使用。
Glioblastoma multiforme (GBM) is an incurable form of brain cancer with a very poor prognosis. Because of its highly invasive nature, it is impossible to remove all tumor cells during surgical resection, making relapse inevitable. Further research into the regulatory mechanism underpinning GBM pathogenesis is therefore warranted, and over the past decade, there has been an increased focus on the functional role of microRNA (miRNA). This systematic review aims to present a comprehensive overview of all the available literature on the expression profiles and function of miRNA in GBM. Here, we have reviewed 163 papers and identified 253 upregulated, 95 downregulated, and 17 disputed miRNAs with respect to expression levels; 85 % of these miRNAs have not yet been functionally characterized. A focus in this study has been 26 interesting miRNAs involved in the mesenchymal mode of migration and invasion, demonstrating the importance of miRNAs in the context of the cellular niche. Both oncogenic and tumor-suppressive miRNAs were found to affect target genes involved in cell migration, cytoskeletal rearrangement, invasiveness, and angiogenesis. Clearly, the distinct functional properties of these miRNAs need further investigation and might hold a great potential in future molecular therapies targeting GBM.
