Abstract

Cancer cells display distinct aneuploid karyotypes (i.e., abnormal chromosome numbers) and typically mis-segregate chromosomes at high rates, a phenotype referred to as chromosomal instability (CIN). Recent studies have shown that anaphase lagging chromosomes arising due to merotelic kinetochore att ...
