哺乳动物的基因表达模式在低氧水平下会发生深刻的变化。基因表达程序的这些变化受到mRNA结合因子(RNA结合蛋白(RBP)和microRNA(miRNA))介导的转录后机制的强烈影响。在这里,我们审查的RBP和miRNA的调节mRNA周转和翻译,以应对缺氧的挑战。RBP如HuR(人抗原R)、PTB(多聚嘧啶片段结合蛋白)、异质核核糖核蛋白(hnRNP)、三曲脯氨酸、核仁素、铁反应元件结合蛋白(IRP)和细胞质多聚腺苷酸化元件结合蛋白(CPEB)选择性地结合许多低氧调节的转录物,并在建立低氧基因表达模式中起主要作用。包括miR-210、miR-373和miR-21的miRNA与低氧调节的转录物相关,并进一步调节编码蛋白的水平以实现低氧基因表达谱。我们讨论了RBP和miRNA对缺氧基因表达的有效调控及其在细胞缺氧反应中的综合作用。
Mammalian gene expression patterns change profoundly in response to low oxygen levels. These changes in gene expression programs are strongly influenced by post-transcriptional mechanisms mediated by mRNA-binding factors: RNA-binding proteins (RBPs) and microRNAs (miRNAs). Here, we review the RBPs and miRNAs that modulate mRNA turnover and translation in response to hypoxic challenge. RBPs such as HuR (human antigen R), PTB (polypyrimidine tract-binding protein), heterogeneous nuclear ribonucleoproteins (hnRNPs), tristetraprolin, nucleolin, iron-response element-binding proteins (IRPs), and cytoplasmic polyadenylation-element-binding proteins (CPEBs), selectively bind to numerous hypoxia-regulated transcripts and play a major role in establishing hypoxic gene expression patterns. MiRNAs including miR-210, miR-373, and miR-21 associate with hypoxia-regulated transcripts and further modulate the levels of the encoded proteins to implement the hypoxic gene expression profile. We discuss the potent regulation of hypoxic gene expression by RBPs and miRNAs and their integrated actions in the cellular hypoxic response.
