Abstract
Telomeres are TTAGGG repetitive motifs found at the ends of vertebrate chromosomes. In humans, telomeres are protected by shelterin, a complex of six proteins (de Lange [2005] Genes Dev. 19: 2100β2110). Since (MΓΌller [1938] Collecting Net. 13: 181β198; McClintock [1941] Genetics 26: 234β282), their function in maintaining chromosome stability has been intensively studied. This interest, especially in cancer biology, stems from the fact that telomere dysfunction is linked to genomic instability and tumorigenesis (Gisselsson et al. [2001] Proc. Natl. Acad. Sci. USA 98: 12683β12688; Deng et al. [2003] Genes Chromosomes Cancer 37: 92β97; DePinho and Polyak [2004] Nat. Genetics 36: 932β934; Meeker et al. [2004] Clin. Cancer Res. 10: 3317β3326). In the present overview, we will discuss the role of telomeres in genome stability, recent findings on threeβdimensional (3D) changes of telomeres in tumor interphase nuclei, and outline future avenues of research.

## Abstract Unlimited proliferative potential is a hallmark of cancer, and can be achieved through the activation of telomere maintenance mechanisms (TMMs). Most tumors activate telomerase, but a significant minority, mainly of mesenchymal origin, uses a recombinationβbased, alternative lengthening
