Wonsey et al. used time-lapse microscopy to show that depletion of FoxM1 in basal cell carcinoma cells would generate cells that enter mitosis but were unable to complete cell division, resulting in either mitotic catastrophe or endoreduplication, confirming their hypothesis that FoxM1 might regulate genes essential for faithful chromosome segregation and mitosis, including NEK2, CENPA and KIF20A [35]. This evidence concerns the gene KIF20A and basal cell carcinoma.
