Regulation 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 کاملPredominant Role of Hypoxia-Inducible Transcription Factor
Tumor hypoxia induces the up-regulation of a gene program associated with angiogenesis, glycolysis, adaptation to pH, and apoptosis via the hypoxia-inducible transcription factors (Hifs) 1 and 2. Disruption of this pathway has been proposed as a cancer therapy. Here, we use short interfering RNAs to compare specific inactivation of Hif-1 or Hif-2 and show markedly different cell type-specific e...
متن کاملRegulation of oxygen homeostasis by hypoxia-inducible factor 1.
Metazoan organisms are dependent on a continuous supply of O(2) for survival. Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that regulates oxygen homeostasis and plays key roles in development, physiology, and disease. HIF-1 activity is induced in response to continuous hypoxia, intermittent hypoxia, growth factor stimulation, and Ca(2+) signaling. HIF-1 mediates adaptive respons...
متن کاملRegulation of hypoxia-inducible factor-1α by NF-κB
HIF (hypoxia-inducible factor) is the main transcription factor activated by low oxygen tensions. HIF-1alpha (and other alpha subunits) is tightly controlled mostly at the protein level, through the concerted action of a class of enzymes called PHDs (prolyl hydroxylases) 1, 2 and 3. Most of the knowledge of HIF derives from studies following hypoxic stress; however, HIF-1alpha stabilization is ...
متن کاملRegulation of human metabolism by hypoxia-inducible factor.
The hypoxia-inducible factor (HIF) family of transcription factors directs a coordinated cellular response to hypoxia that includes the transcriptional regulation of a number of metabolic enzymes. Chuvash polycythemia (CP) is an autosomal recessive human disorder in which the regulatory degradation of HIF is impaired, resulting in elevated levels of HIF at normal oxygen tensions. Apart from the...
