Web1 nov. 2013 · In hypoxic conditions ( Left ), hypoxia-inducible factor (HIF) α and HIF-β subunits translocate to the nucleus, where they bind as heterodimers to a hypoxia response promoter element (HRE), inducing transcription of numerous genes, including those of nuclear factor κB (NF-κB) and toll-like receptors (TLRs). Web22 okt. 2024 · The main types of hypoxia include: 2. Hypoxic hypoxia (hypoxemic hypoxia) : There is a lack of oxygen in the blood flowing to the tissues. Hypemic hypoxia : Blood isn't able to carry oxygen as well as it should. Often this is because of an insufficient amount of healthy red blood cells. This leads to a lower supply of oxygen in the tissues.
