Caspase-3 Gene Knockout Defines Cell Lineage Specificity for Programmed Cell Death Signaling in the Ovary*

Abstract excerpt

Previous studies have proposed the involvement of caspase-3, a downstream executioner enzyme common to many paradigms of programmed cell death (PCD), in mediating the apoptosis of both germ and somatic cells in the ovary. Herein we used caspase-3 gene knockout mice to directly test for the functional requirement of this protease in oocyte and/or granulosa cell demise. Using both in vivo and in vitro approaches,...
