Chromosomal breakage-fusion-bridge events cause genetic intratumor heterogeneity

Gisselsson, David, Pettersson, Louise, Höglund, Mattias, Heidenblad, Markus, Gorunova, Ludmila, Wiegant, Joop, ...

It has long been known that rearrangements of chromosomes through breakage-fusion-bridge (BFB) cycles may cause variability of phenotypic and genetic traits within a cell population. Because...

Telomere dysfunction triggers extensive DNA fragmentation and evolution of complex chromosome abnormalities in human malignant tumors

Gisselsson, David, Jonson, Tord, Petersén, Åsa, Strömbeck, Bodil, Dal Cin, Paola, Höglund, Mattias, ...

Although mechanisms for chromosomal instability in tumors have been described in animal and in vitro models, little is known about these processes in man. To explore cytogenetic evolution in human...

Structural and numerical chromosome changes in colon cancer develop through telomere-mediated anaphase bridges, not through mitotic multipolarity

Stewénius, Ylva, Gorunova, Ludmila, Jonson, Tord, Larsson, Nina, Höglund, Mattias, Mandahl, Nils, ...

Telomere dysfunction has been associated with chromosomal instability in colorectal carcinoma, but the consequences of telomere-dependent instability for chromosome integrity and clonal evolution...

Limitations of Chromosome Classification by Multicolor Karyotyping

Lee, Charles, Gisselsson, David, Jin, Charlotte, Nordgren, Ann, Ferguson, David O., Blennow, Elisabeth, ...

Multicolor karyotyping technologies, such as spectral karyotyping (SKY) (Schröck et al. 1996; Liyanage et al. 1996) and multiplex (M-) FISH (Speicher et al. 1996), have proved to be extremely useful...
