Hypoxia and hypoxia-inducible factors in chronic kidney disease
It is generally accepted that renal hypoxia plays an important role in the progression of chronic kidney disease (CKD). This review focuses on renal hypoxia and hypoxia-inducible factor (HIF), a master regulator of cellular adaptation to hypoxia, during CKD progression. The kidney, which is physiologically hypoxic, is exposed to increased levels of hypoxia in CKD; insufficient oxygenation in th...
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...
متن کاملHypoxia-inducible factors in the kidney.
Tissue hypoxia not only occurs under pathological conditions but is also an important microenvironmental factor that is critical for normal embryonic development. Hypoxia-inducible factors HIF-1 and HIF-2 are oxygen-sensitive basic helix-loop-helix transcription factors, which regulate biological processes that facilitate both oxygen delivery and cellular adaptation to oxygen deprivation. HIFs ...
متن کاملHypoxia-inducible factors and kidney vascular development.
Among the genes strongly induced by hypoxia-inducible factors (HIF) and highly expressed during kidney microvascular development is vascular endothelial growth factor, which encodes a potent endothelial mitogen and chemoattractant critical for embryonic vasculogenesis and angiogenesis. In developing kidney, glomerular podocytes are particularly rich sources of vascular endothelial growth factor...
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...
