Telomere dysfunction triggers developmentally regulated germ cell apoptosis
(American Society for Cell Biology, 2001-07)
Telomere dysfunction results in fertility defects in a number of organisms. Although data from fission yeast and Caenorhabditis elegans suggests that telomere dysfunction manifests itself primarily as defects in proper ...
The Shortest Telomere, Not Average Telomere Length, Is Critical for Cell Viability and Chromosome Stability
(Cell Press, 2001-10-05)
Loss of telomere function can induce cell cycle arrest and apoptosis. To investigate the processes that trig- ger cellular responses to telomere dysfunction, we crossed mTR/ G6 mice that have short telomeres with mice ...
Short dysfunctional telomeres impair tumorigenesis in the INK4a(delta2/3) cancer-prone mouse.
(Cell Press, 1999-05-14)
Maintenance of telomere length is predicted to be essential for bypass of senescence and crisis checkpoints in cancer cells. The impact of telomere dysfunction on tumorigenesis was assessed in successive generations of ...
p53 Deficiency Rescues the Adverse Effects of Telomere Loss and Cooperates with Telomere Dysfunction to Accelerate Carcinogenesis
(Cell Press, 1999-05-14)
Maintenance of telomere length and function is critical for the efficient proliferation of eukaryotic cells. Here, we examine the interactions between telomere dysfunction and p53 in cells and organs of telomerase-deficient ...
Short telomeres and ataxia-telangiectasia mutated deficiency cooperatively increase telomere dysfunction and suppress tumorigenesis
(American Association of Cancer Research, 2003-12-01)
To examine the role of ataxia-telangiectasia mutated (Atm) in telomere function, we generated Atm and telomerase null mice (Atm(-/-) mTR(-/-) iG6 mice). These mice exhibited increased germ cell death and chromosome fusions ...
