Web28 de nov. de 2024 · Activation of OET does not need new transcripts, mainly based on the maternal RNA and protein accumulated in fully grown oocytes (FGOs). In this process, the function of nucleus has radical changes: differentiated egg and sperm combine to produce the embryo genome. WebOocyte-to-Embryo Transition (OET) requires a coordinated transcriptional program acting through evolutionarily conserved events.

Web30 de jul. de 2016 · Oocyte maturation involves the release of the primary meiotic arrest at prophase I and progression of the oocyte nucleus into meiotic divisions to produce a mature oocyte (egg) capable of being fertilized ( Von Stetina and Orr-Weaver, 2011 ). The mature oocyte is arrested in metaphase II in most vertebrates and metaphase I in insects.

WebThe FGO contains all the transcripts necessary to activate the molecular pathways required for oocyte-to-embryo transition (OET) and early embryogenesis ( Pennetier et al., 2004 Cui and Kim, 2007). Completion of meiosis is dependent on fertilization that triggers progression to anaphase II coupled with the formation of the first mitotic interphase.
