Abstract

Mitochondria can initiate cell death or activate genes that promote cell survival in response to low oxygen. The BCL-2 family of proteins regulate cell death in response to anoxia (0-0.5% O2). By contrast, under hypoxia (0.5-3% O2), mitochondrial oxidative stress activates hypoxia-inducible factors (HIFs) to promote cell survival. In this review, we discuss how mitochondria, BCL-2 proteins, and HIFs are crucial for cellular responses to low oxygen. Antioxid. Redox Signal. 11, 2673-2683.
