## Abstract 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 ch

Abstract
Telomeres are the ends of chromosomes and protect them from degradation and fusion. As such, their stability is required for normal cellular function. Telomere dysfunction is found often at the origin of cellular transformation and contributes to the onset of genomic instability, a hallmark of cancer cells. In this article, I discuss current data and concepts on telomereโmediated chromosomal rearrangements in cancer. J. Cell. Biochem. 109: 1095โ1102, 2010. ยฉ 2010 WileyโLiss, Inc.

## Abstract A study was undertaken to correlate telomere dysfunction and genomic instability with the histopathological grades and the estrogen and progesterone receptor status in breast cancer. Sixtyโone archived breast tissues (38 cancer tissues and 23 paired normal tissues) were used in the stud
The molecular events involved in pancreatic cancer are becoming increasingly well characterized, with mutations in the dominant oncogene KRAS and the tumour suppressor genes TP53, CDKN2A and MADH4 being typically observed. However, other genetic abnormalities remain to be identified and molecular cy
## Abstract Ovarian carcinomas (OCs) often exhibit highly complex cytogenetic changes. Abnormal chromosome segregation at mitosis is one potential mechanism for genomic rearrangements in tumors. In this study, OCs were demonstrated to have dysfunctional short telomeres, anaphase bridging, and multi
