1 In vitro, the oxygen-regulated subunits HIF-1alpha and -2alpha are expressed in inverse relationship to oxygen tensions in every cell line investigated to date. Oxygen hypoxia inducible factor 1 subunit alpha Rattus norvegicus
2 In vitro, the oxygen-regulated subunits HIF-1alpha and -2alpha are expressed in inverse relationship to oxygen tensions in every cell line investigated to date. Oxygen hypoxia inducible factor 1 subunit alpha Rattus norvegicus
3 High-amplification immunohistochemical analyses were used to study the expression of HIF-1alpha and -2alpha in kidneys of rats exposed to systemic hypoxia bleeding anemia, functional anemia (0.1% carbon monoxide), renal ischemia, or cobaltous chloride (which is known to mimic hypoxia). Carbon Monoxide hypoxia inducible factor 1 subunit alpha Rattus norvegicus
4 High-amplification immunohistochemical analyses were used to study the expression of HIF-1alpha and -2alpha in kidneys of rats exposed to systemic hypoxia bleeding anemia, functional anemia (0.1% carbon monoxide), renal ischemia, or cobaltous chloride (which is known to mimic hypoxia). cobaltous chloride hypoxia inducible factor 1 subunit alpha Rattus norvegicus
5 HIF-1alpha was mainly induced in tubular cells, including proximal segments with exposure to anemia/carbon monoxide, in distal segments with cobaltous chloride treatment, and in connecting tubules and collecting ducts with all stimuli. Carbon Monoxide hypoxia inducible factor 1 subunit alpha Rattus norvegicus
6 HIF-1alpha was mainly induced in tubular cells, including proximal segments with exposure to anemia/carbon monoxide, in distal segments with cobaltous chloride treatment, and in connecting tubules and collecting ducts with all stimuli. Chlorides hypoxia inducible factor 1 subunit alpha Rattus norvegicus
7 The kidney demonstrates a marked potential for upregulation of HIF, but accumulation of HIF-1alpha and HIF-2alpha is selective with respect to cell type, kidney zone, and experimental conditions, with the expression patterns partly matching known oxygen profiles.
