Witrynanecrosis. Death of some or all cells in an organ or tissue. The process involves swelling of the nucleus (pyknosis), fragmentation of the nucleus (karyorrhexis) and complete dissolution of the nuclear chromatin (karyolysis). Necrosis is caused by disease, trauma or interference with blood supply. WitrynaMeanwhile, acute and chronic hypoxia are combined in frequently in cancer tissues leading to central tumor necrosis and surrounded by hypoxic areas . Chronic hypoxia may induce physiological responses in tumor tissue, but in case of genetic changes of the signaling pathway components, this response could be profoundly different [ 6 ].
