WebMar 13, 2024 · Definition. Chromosome instability describes the increased probability of acquiring chromosomal aberrations due to defects in processes such as DNA repair, replication or chromosome segregation. WebAn aged or damaged somatic cell experiences an identity transformation, including cytoskeletal modification, to become a tumor preinitiation cell, which then undergoes senescence, resulting in an increase in cell size.
WebChromosomal instability is the predominant form of genomic instability that leads to changes in both chromosome numbers and structure [84]. Numerical CIN is a high rate of either gain or loss of whole chromosomes, also called aneuploidy.
