Regulation of erythropoiesis by hypoxia-inducible factors.
A classic physiologic response to systemic hypoxia is the increase in red blood cell production. Hypoxia-inducible factors (HIFs) orchestrate this response by inducing cell-type specific gene expression changes that result in increased erythropoietin (EPO) production in kidney and liver, in enhanced iron uptake and utilization and in adjustments of the bone marrow microenvironment that facilita...
متن کاملThe transcription of Hypoxia-inducible factors (hif-1, hif-2) during normal development of Beluga sturgeon (Huso huso Linnaeus, 1758)
In the present study, the levels of the hypoxia-inducible factors (hif-1, hif-2) transcripts were evaluated during development of an ancient fish species, Beluga sturgeon (Huso huso) in a normal oxygen environment. The transcripts of hif-1, hif-2 were detected in all developmental time-points of H. huso from embryos to juvenile fish. Changes in normalized hif-1, hif-2 mRNA expression by using t...
متن کاملRegulation of hypoxia-inducible genes by ETS1 transcription factor.
Hypoxia-inducible factor (HIF-1) regulates the expression of genes that facilitate tumor cell survival by making them more resistant to therapeutic intervention. Recent evidence suggests that the activation of other transcription factors, in cooperation with HIF-1 or acting alone, is involved in the upregulation of hypoxia-inducible genes. Here we report that high cell density, a condition that...
متن کاملRegulation of iron homeostasis by the hypoxia-inducible transcription factors (HIFs).
Iron is essential for many biological processes, including oxygen delivery, and its supply is tightly regulated. Hepcidin, a small peptide synthesized in the liver, is a key regulator of iron absorption and homeostasis in mammals. Hepcidin production is increased by iron overload and decreased by anemia and hypoxia; but the molecular mechanisms that govern the hepcidin response to these stimuli...
متن کاملHypoxia-inducible transcription factors and their role in renal disease.
The 2 hypoxia inducible factors (HIF)-1alpha and HIF-2alpha are key mediators of cellular adaptation to hypoxia. They show a specific distribution pattern and possibly have complementary transcriptional targets in the kidney: HIF-1alpha is found mainly in tubular and HIF-2alpha in peritubular interstitial, endothelial, and glomerular cells. Both isoforms are regulated by oxygen-dependent hydrox...
