Effects of iron supplementation and depletion on hypoxic pulmonary hypertension: two randomized controlled trials.

5 Oct 2009 CONTEXT: Hypoxia is a major cause of pulmonary hypertension in respiratory disease and at high altitude. Recent work has established that the effect of hypoxia on pulmonary arterial pressure may depend on iron status, possibly acting through the ... Read more...

The glial cell response is an essential component of hypoxia-induced erythropoiesis in mice.

3 Oct 2009 A key adaptation to environmental hypoxia is an increase in erythropoiesis, driven by the hormone erythropoietin (EPO) through what is traditionally thought to be primarily a renal response. However, both neurons and astrocytes (the largest ... Read more...

The role of NF-kappaB in hypoxia-induced gene expression.

29 Sep 2009 Hypoxia is a common physiologic and pathophysiologic stimulus that activates the expression of genes through oxygen-sensitive transcription factors including the hypoxia-inducible factor (HIF) and nuclear factor-kappaB (NF-kappaB). Hypoxia-dependent ... Read more...
