Chromosomal instability through spindle assembly checkpoint alleviation facilitates malignant transformation of hepatocytes and T-cells in vivo, resulting in cancers with recurrent karyotypes.
Chromosomal instability of cancer can be quantitatively measured by phylogenetic analysis of 200 tumor cells while using evolutionary principles to account for cellular selection.
Genetic analyses reveal that purely quantitative changes in the relative copy number of chromosomes can be sufficient to disrupt the epigenetic mechanisms that define the cells' differentiated state.
Human cell lines regress to become ‘de-sexualized’ by reconfiguring to a 2:3 X/A ratio of high fitness, thus shedding light on the evolution of mammalian sex chromosomes.
