The Genomic Landscape of Centromeres in Cancers

WebJul 7, 2024 · Centromeres are the genomic regions that organize and regulate chromosome behaviours during cell cycle, and their variations are associated with genome instability, karyotype evolution and speciation in eukaryotes. The highly repetitive and epigenetic nature of centromeres were documented during the past half century. WebFeb 23, 2016 · Here we describe the detailed mechanism and chronology of centromere repeat replacement, and identify inbreeding as a major driver of centromeric DNA replacement that ultimately gives rise to new tandem centromere repeats at genetically indistinguishable loci.
