Abstract:
Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that mediates essential homeostatic responses to reduced O2 availability in mammals. Recent studies have provided insights into the O2-dependent regulation of HIF-1 expression, target genes regulated by HIF-1, and the effects of HIF-1 deficiency on cellular physiology and embryonic development.
