Is hypoxia necrosis
Witryna2 lis 2024 · One of the major consequences of shock is that the tissues don’t get enough oxygen and nutrients, a condition known as ischaemia. This begins a cascade of bad things that can eventually cause necrosis. The hypoxia causes the tissues to switch to glycolysis, which is anaerobic. This switch has two consequences: the tissues … WitrynaAlthough hypoxia caused by embolization can induce apoptosis and necrosis of the majority of tumor cells, a small proportion of cells can survive with hypoxia and chemotherapy resistance. HIF-1α induced by hypoxia is the key factor rendering surviving tumor cells invasive and metastatic properties.
