| Outline of Final Research Achievements |
Chromothripsis is a catastrophic cellular event in cancer, in which chromosomes undergo localized massive copy number alterations and rearrangements. However the causes and consequences of chromothripsis are almost unclear. We investigated whether chromothripsis was artificially induced by irradiation with the Single Particle Irradiation system to Cell (SPICE), a focused vertical micro-beam system designed to irradiate the nuclei of adhesive cells. Multiple chromosomal alterations involved in chromosome 7 with a complex translocation, suggesting chromothripsis to be induced in part by irradiation.
