低氧诱导因子(hif)调节多种基因,使细胞在低氧环境下适应和生存。最近,microRNAs (miRNAs)作为一类新的基因被HIF调控以应对缺氧,其中miR-210是最一致和主要上调的miRNA。功能研究表明,miR-210是一个多用途基因,在生理和恶性条件下调节缺氧途径的许多方面。在这里,我们总结了缺氧调节miR-210表达的机制及其在正常生理和恶性条件下的多方面生物学功能的最新发现,并讨论了我们在阐明miR-210的生物学功能和探索其潜在治疗用途方面面临的挑战。
Hypoxia inducible factors (HIFs) regulate a variety of genes to prepare cells to adapt and to survive under a hypoxic environment. Recently, microRNAs (miRNAs) have emerged as a new class of genes regulated by HIF in response to hypoxia, of which miR-210 is the most consistently and predominantly upregulated miRNA. Functional studies have demonstrated that miR-210 is a versatile gene that regulates many aspects of hypoxia pathways, both in physiological and malignant conditions. Here, we summarize recent findings on the mechanism of hypoxia regulation of miR-210 expression and its multifaceted biological functions in normal physiological and malignant conditions and discuss challenges we face in elucidating the biological functions of miR-210 and in exploring its potential use for therapeutics.
