细胞通常对压力反应迅速,改变它们的新陈代谢来补偿。在哺乳动物细胞中,应激信号通常导致细胞周期停滞或凋亡,这取决于损伤的严重程度和细胞的恢复能力。应激还经常导致核结构的重组,反映了主要核途径的同时抑制(例如,复制和转录)和特异性应激反应的激活(例如,DNA修复)。在这篇综述中,我们集中在两个核细胞器,核仁和卡哈尔体,如何应对压力。核仁感知压力,是协调压力反应的中心枢纽。我们回顾核仁的功能,在压力诱导的调节p53和特定的变化,核仁的形态和组成,发生在压力。核仁和CBs之间的串扰也讨论了压力反应的背景下。
Cells typically respond quickly to stress, altering their metabolism to compensate. In mammalian cells, stress signaling usually leads to either cell-cycle arrest or apoptosis, depending on the severity of the insult and the ability of the cell to recover. Stress also often leads to reorganization of nuclear architecture, reflecting the simultaneous inhibition of major nuclear pathways (e.g., replication and transcription) and activation of specific stress responses (e.g., DNA repair). In this review, we focus on how two nuclear organelles, the nucleolus and the Cajal body, respond to stress. The nucleolus senses stress and is a central hub for coordinating the stress response. We review nucleolar function in the stress-induced regulation of p53 and the specific changes in nucleolar morphology and composition that occur upon stress. Crosstalk between nucleoli and CBs is also discussed in the context of stress responses.
