遗传物质在真核细胞中的忠实传递不仅需要准确的DNA复制和染色体分布,还需要感知和修复自发和诱导的DNA损伤的能力。为了维持基因组的完整性,细胞使用复杂的信号通路网络进行DNA损伤反应,该信号通路网络由细胞周期停滞、凋亡和DNA修复中的坐标传感器、转换器和效应器组成。新出现的证据表明,microRNAs(miRNAs)在调节DNA损伤反应中起着关键作用。在这里,我们讨论了最近的研究结果,如何与典型的DNA损伤反应的miRNA的相互作用,以及如何在DNA损伤后的miRNA表达的调节。
Faithful transmission of genetic material in eukaryotic cells requires not only accurate DNA replication and chromosome distribution, but also the ability to sense and repair spontaneous and induced DNA damage. To maintain genomic integrity, cells undergo a DNA damage response using a complex network of signaling pathways, composed of coordinate sensors, transducers and effectors in cell cycle arrest, apoptosis and DNA repair. Emerging evidence has suggested that microRNAs (miRNAs) play a critical role in regulation of DNA damage response. Here, we discuss the recent findings on how miRNAs interact with the canonical DNA damage response and how miRNA expression is regulated after DNA damage.
