Hypoxia-inducible factor 2alpha regulates macrophage function in mouse models of acute and tumor inflammation.

Hypoxia-inducible factor 1alpha (HIF-1alpha) and HIF-2alpha display unique and sometimes opposing activities in regulating cellular energy homeostasis, cell fate decisions, and oncogenesis. Macrophages exposed to hypoxia accumulate both HIF-1alpha and HIF-2alpha, and overexpression of HIF-2alpha in ... View More
