Wnt/β-Catenin Signaling Regulates Telomerase in Stem Cells and Cancer Cells
21 Jun 2012
Abstract excerpt
Telomerase activity controls telomere length and plays a pivotal role in stem cells, aging, and cancer. Here, we report a molecular link between Wnt/β-catenin signaling and the expression of the telomerase subunit Tert. β-Catenin-deficient mouse embryonic stem (ES) cells have short telomeres; conversely, ES cell expressing an activated form of β-catenin (β-cat(ΔEx3/+)) have long telomeres. We show that β-catenin...
