- GENOMIC INSTABILITY IN TELOMERASE AND AGING MOUSE MODELSSandy Chang; Fiscal Year: 2003..Guarente s lab. The hypotheses are that these mice will represent models for human aging, and that the combination of both strains will generate animals with increased genomic instability. ..
- Telomere induced senescence as a supressor of tumorigenesisSandy Chang; Fiscal Year: 2009..It is likely that up regulation of p53 function by compounds currently undergoing clinical trials would favor the activation of the cellular senescence program, resulting in suppression of breast cancer. ..
- The role of the telomere capping protein POT1 in mammalian agingSandy Chang; Fiscal Year: 2009..Given increasing evidence that telomere attrition reduces lifespan in humans, we believe our findings will be relevant to human aging as well. ..
- The role of the telomere capping protein POT1 in mammalian agingSandy Chang; Fiscal Year: 2007..Given increasing evidence that telomere attrition reduces lifespan in humans, we believe our findings will be relevant to human aging as well. ..
- Telomere induced senescence as a supressor of tumorigenesisSandy Chang; Fiscal Year: 2007..It is likely that up regulation of p53 function by compounds currently undergoing clinical trials would favor the activation of the cellular senescence program, resulting in suppression of breast cancer. ..
- Telomere Induced Genomic Instability in Premature AgingSandy Chang; Fiscal Year: 2006..We are also probing for molecular mechanisms that may be responsible for the observed aging phenotypes in our mouse model. These studies should illuminate the roles of Wrn and dysfunctional telomeres during human aging. ..
- Characterization of a Mouse Model of Werner SyndromeSandy Chang; Fiscal Year: 2005..These studies should establish a role for WRN function in mammalian telomere biology and lend support to the notion that telomeres play a causative role in mammalian aging. ..
