后生动物通过激活应激反应途径适应低氧环境(缺氧)。在这里,我们报告说,短暂缺氧暴露延长寿命的C。通过线粒体ROS依赖性调节营养传感激酶TOR及其上游激活剂RHEB-1,缺氧期间寿命的增加需要TOR信号下游的肠GATA型转录因子ELT-2。使用RNA测序,我们描述了ELT-2依赖的缺氧反应,包括肠道谷胱甘肽S-转移酶,GSTO-1,并发现GSTO-1是缺氧条件下的寿命所需的。这些结果表明线粒体ROS依赖性TOR信号转导整合了代谢适应以赋予缺氧下的存活。
Metazoans adapt to a low oxygen environment (hypoxia) through activation of stress response pathways. Here we report that transient hypoxia exposure extends lifespan in C. elegans through mitochondrial ROS-dependent regulation of the nutrient sensing kinase TOR and its upstream activator RHEB-1. The increase in lifespan during hypoxia requires the intestinal GATA-type transcription factor, ELT-2, downstream of TOR signaling. Using RNA-Sequencing, we describe an ELT-2-dependent hypoxia response that includes an intestinal glutathione S-transferase, GSTO-1, and uncover that GSTO-1 is required for lifespan under hypoxia. These results indicate mitochondrial ROS-dependent TOR signaling integrates metabolic adaptations to confer survival under hypoxia.
