Polyploid giant cells arise by endo\u2010reduplication in the first week after a single 10 Gray dose of irradiation. Within the giant cells a sub\u2010nuclear structure is apparent and within this, sub\u2010nuclear autonomy is evident, as displayed by independent nuclear structure and DNA replication in different parts of the nucleus. The majority of these cells soon die as apoptotic polykaryons. However, approximately 10\u201320% of giant cells remain viable into the second week after irradiation and begin vigorous extrusion of large degraded chromatin masses. During the second week, the giant cells begin to reconstruct their nuclei into polyploid \u2018bouquets\u2019, where chromosome double\u2010loops are formed. Subsequently, the bouquets return to an interphase state and separate into several secondary nuclei. The individual sub\u2010nuclei then resume DNA synthesis with mitotic divisions and sequester cytoplasmic territories around themselves, giving rise to the secondary cells, which continue mitotic propagation. This process of giant cell formation, reorganization and breakdown appears to provide an additional mechanism for repairing double\u2010strand DNA breaks within tumour cells.<\/jats:p>","DOI":"10.1006\/cbir.2000.0558","type":"journal-article","created":{"date-parts":[[2002,9,16]],"date-time":"2002-09-16T14:51:08Z","timestamp":1032187868000},"page":"635-648","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":101,"title":["RELEASE OF MITOTIC DESCENDANTS BY GIANT CELLS FROM IRRADIATED BURKITT'S LYMPHOMA CELL LINES"],"prefix":"10.1002","volume":"24","author":[{"given":"Jekaterina A.","family":"Erenpreisa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark S.","family":"Cragg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Birgitta","family":"Fringes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Igor","family":"Sharakhov","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy M.","family":"Illidge","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,1,2]]},"container-title":["Cell Biology International"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1006%2Fcbir.2000.0558","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1006\/cbir.2000.0558","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,29]],"date-time":"2023-10-29T11:11:51Z","timestamp":1698577911000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1006\/cbir.2000.0558"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,9]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2000,9]]}},"alternative-id":["10.1006\/cbir.2000.0558"],"URL":"https:\/\/doi.org\/10.1006\/cbir.2000.0558","archive":["Portico"],"relation":{},"ISSN":["1065-6995","1095-8355"],"issn-type":[{"value":"1065-6995","type":"print"},{"value":"1095-8355","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,9]]},"assertion":[{"value":"2013-01-02","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
