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. WebAbstract. The oocyte-to-embryo transition (OET) occurs in the absence of new transcription and relies on post-transcriptional gene regulation, including translational control by mRNA poly(A) tail regulation, where cytoplasmic polyadenylation activates translation and deadenylation leads to translational repression and decay.

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. 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.
