abstractText | Maternal effect factors derived from oocytes are important for sustaining early embryonic development before the major wave of embryonic genome activation (EGA). In this study, we report a two-cell-stage arrest of embryos lacking maternal 3-phosphoinositide-dependent protein kinase 1 as a result of suppressed EGA. Concurrent deletion of maternal Pten completely rescued the suppressed EGA and embryonic progression through restored AKT signalling, which fully restored the fertility of double-mutant females. Our study identifies maternal phosphatidylinositol 3-kinase signalling as a new maternal effect factor that regulates EGA and preimplantation embryogenesis in mice. |
