dc.description.abstract | HCT116 (p53+/+) human colon carcinoma cells treated with nanomolar concentrations of doxorubicin underwent transient senescence, synthesized DNA, showed endopolyploidization, increased their size and became multinucleated without a significant increase in mitosis. Nuclei underwent a budding process that involved the release of buds outside the nuclear membrane, and some of the buds seemed to escape from the polyploid cells. A clonogenic assay showed that some cells proliferated following the initial treatment. In general, cells ensuing after budding were not resistant to a variety of drugs, although some of them turned out to be resistant, indicating a potential selective advantage. Nuclear budding was accompanied by changes in protein levels in the giant cells, including inhibition of p53 and enhanced expression of p21WAF1 and the meiosis-related Mos. The buds might be a mechanism for the segregation and elimination of redundant DNA, or for generating viable aneuploid cells with a potentially extended life span. © 2009 Elsevier Inc.
