Activation of p53-Dependent Apoptosis by Acute Ablation of Glycogen Synthase Kinase-3β in Colorectal Cancer Cells

Abstract
Purpose: The restoration of checkpoint mechanisms may provide a rational anticancer approach, but the molecular circuitries of how this can be achieved therapeutically are poorly understood. A pivotal signaling network in colorectal cancer cells involves glycogen synthase kinase-3β (GSK3β), a multifunctional kinase whose role in tumor cell survival is not defined.
