Chromosome rearrangements resulting from telomere dysfunction and their role in cancer

Abstract excerpt

Telomeres play a vital role in protecting the ends of chromosomes and preventing chromosome fusion. The failure of cancer cells to properly maintain telomeres can be an important source of the chromosome instability involved in cancer cell progression. Telomere loss results in sister chromatid fusion and prolonged breakage/fusion/bridge (B/F/B) cycles, leading to extensive DNA amplification and large deletions....
