Whole-genome doubling drives oncogenic loss of chromatin segregation

Elisa Oricchio, Natalya Katanayeva, Daniele Tavernari, Ruxandra-Andreea Lambuta, Juan Diaz Miyar

Whole-genome doubling (WGD) is a recurrent event in human cancers and it promotes chromosomal instability and acquisition of aneuploidies(1-8). However, the three-dimensional organization of chromatin in WGD cells and its contribution to oncogenic phenotyp ...
