CTNND1 and cervical squamous intraepithelial neoplasia: In addition, we quantified the frequency of lagging chromosomes in U2OS p120-iKD cells and did not observe an increase after one passage on dox (−dox: 10/34; +dox: 6/23; P=0.428) indicating that the induction of CIN through loss of p120 is not caused by early chromosome segregation errors.
