abnormal mitosis ( J:126471 )
• 36% of mouse embryonic fibroblasts (MEFs) transfected with an adenovirus cre vector exhibit abnormal mitosis similar to in Tacc3tm1Tno MEFs and produce binucleated cells, 7.8% of cells produce 3 or 4 cells after cytokinesis and 22% of cells fail to separate sister chromatids
• however, 37% of transfected MEFs complete mitosis normally

neoplasm
increased T cell derived lymphoma incidence ( J:179414 )
• in the absence of 4OHT, mutants develop thymic lymphoma tumors
decreased lymphoma incidence ( J:179414 )
• administration of 4-hydroxytamoxifen (4OHT) to induce Cre recombination results in regression of autochthonous thymic lymphoma, with a reduction in tumor volume to 96% and 26% of original volume, over 3 and 10 days, respectively
• regression of tumors is due to apoptosis in thymic lymphoma
• 4OHT treatment of mutants results in massive apoptosis in thymic lymphomas but not in normal thymic tissue or other tissues
• lymphoma cells contain multi-polar spindles, indicating aberrant spindle formation, resulting in mitotic arrest and rapid cell death

endocrine/exocrine glands
increased T cell derived lymphoma incidence ( J:179414 )
• in the absence of 4OHT, mutants develop thymic lymphoma tumors
