WebHIFs mainly control transcription of genes for angiogenesis, erythropoiesis and glycolysis in response to hypoxia. In normoxia HIF-α’s are constantly degraded. Degradation is prevented in hypoxia, the HIF-α’s form heterodimers with HIF-β’s, translocate to the nucleus and become transcriptionally active. Web6 de set. de 2024 · In turn, HIF induces VEGF expression and angiogenesis. HBOT is thought to promote HIF-1alpha hydroxylation by spurring the formation of ROS via the cycling between hyperoxic and hypoxic states that occurs after HBOT treatments. As HBOT increases the rate of angiogenesis, there exist myriad indications for its utilization.
