Unraveling the Functional Complexity of Cancer Genomes through Chromosome Engineering

Cancers arise through genetic and epigenetic alterations that drive the transformation of single cells into malignant tumors. Among genetic changes, copy number alterations (CNAs) are recurrent chromosomal events that increase or decrease the dosage of specific regions of DNA, can affect up to 30% of a cancer cell genome, and are associated with poor clinical outcomes. Despite their pervasiveness, the functional effects of specific CNAs on cancer phenotypes remain largely unknown, as current approaches cannot faithfully recapitulate the unique properties of these chromosomal alterations. Indeed, CNAs can uniquely affect the expression of hundreds of linked genes and change DNA topology,…
