"Result showed that overexpression of Oocyte-G1 increased apoptosis in cultured cells. Oocyte-G1 transgenic mice also showed an increased apoptotic rate in male germ cells. Co-localization experiments revealed an interaction between Oocyte-G1 and Caspase-3 and suggest that Oocyte-G1 may promote male germ cell apoptosis through activating Caspase-3."xsd:string
