Constitutive Activation of PI3K in Oocyte Induces Ovarian Granulosa Cell Tumors

Abstract excerpt

Cell-cell interactions play crucial roles in the maintenance of tissue homeostasis, a loss of which often leads to varying diseases, including cancer. Here, we report that uncontrolled PI3K activity within oocytes irreversibly transforms granulosa cells (GC), causing GC tumors (GCT) through perturbed local cell communication. Previously, we reported reproductive phenotypes of transgenic mice, in which expression...
