The regulation of apoptosis is critical for controlling tissue homeostasis and preventing tumor formation and growth. Reactive Oxygen Species (ROS) generation plays a key role in such regulation. Here, we describe a HIF-1 target, ATIA (anti-TNFα-induced apoptosis), which protects cells against TNFα- and hypoxia-induced apoptosis. Through the generation of ATIA knockout mice, we show that ATIA protects cells from apoptosis through regulating the function of the mitochondrial antioxidant, thioredoxin-2, and ROS generation. ATIA is highly expressed in human glioblastoma and ATIA knockdown in glioblastoma cells renders them sensitive to hypoxia-induced apoptosis. Therefore, ATIA is not only a HIF-1 target that regulates mitochondrial redox pathways but a potentially diagnostic marker and therapeutic target in human glioblastoma.
