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.
