The molecular response of cancer cells to hypoxia is the focus of intense research. In the last decade, research into microRNAs (miRNAs), small RNAs which have a role in regulation of mRNA and translation, has grown exponentially. miR-210 has emerged as the predominant miRNA regulated by hypoxia. Elucidation of its targets points to a variety of roles for this, and other hypoxia-regulated miRNAs (HRMs), in tumour growth and survival. miR-210 expression correlates with poor survival in cancer patients, and shows promise for future use as a tumour marker or therapeutic agent. The role of miR-210 and other HRMs in cancer biology is the subject of this review.
癌细胞对缺氧的分子反应是目前研究的重点。在过去十年中,对 microRNAs(miRNAs)的研究——一种在 mRNA 和翻译调控中起作用的小 RNA——呈指数级增长。miR-210 是受缺氧调节的主要 miRNA。对其靶标的阐明表明,miR-210 和其他缺氧调节 miRNA(HRMs)在肿瘤生长和存活中具有多种作用。miR-210 的表达与癌症患者的不良预后相关,并且有望在未来用作肿瘤标志物或治疗剂。本文综述了 miR-210 和其他 HRMs 在癌症生物学中的作用。
