[PDF][PDF] SnapShot: hypoxia-inducible factors
Molecular oxygen (O 2) is a key substrate for mitochondrial ATP production and numerous
intracellular biochemical reactions. The maintenance of O 2 homeostasis is therefore
essential for the survival of most species. During O 2 deprivation, mammalian cells rely on
multiple adaptations mediated by the hypoxia-inducible factors (HIFs), mTOR, autophagy,
and the ER stress response. This SnapShot will summarize recent reports expanding our
current understanding of HIF-dependent adaptations to low O 2 levels.
