Dcp1-bodies in mouse oocytes.
Processing bodies (P-bodies) are cytoplasmic granules involved in the storage and degradation of mRNAs. In somatic cells, their formation involves miRNA-mediated mRNA silencing. Many P-body protein components are also found in germ cell granules, such as in mammalian spermatocytes. In fully grown mammalian oocytes, where changes in gene expression depend entirely on translational control, RNA g...
متن کاملMicroinjection of follicle-enclosed mouse oocytes.
The mammalian oocyte develops within a complex of somatic cells known as a follicle, within which signals from the somatic cells regulate the oocyte, and signals from the oocyte regulate the somatic cells. Because isolation of the oocyte from the follicle disrupts these communication pathways, oocyte physiology is best studied within an intact follicle. Here we describe methods for quantitative...
متن کاملPyruvate prevents aging of mouse oocytes.
Inhibiting oocyte aging is important not only for healthy reproduction but also for the success of assisted reproduction techniques. Although our previous studies showed that cumulus cells accelerated aging of mouse oocytes, the underlying mechanism is unknown. The objective of this paper was to study the effects of pyruvate and cumulus cells on mouse oocyte aging. Freshly ovulated mouse cumulu...
متن کاملDistribution of mitochondria in reconstructed mouse oocytes.
It has been suggested that nucleus replacement (transfer) may be used as an efficient oocyte therapy in order to prevent transmission of mutated mitochondrial DNA from mother to offspring in humans. The essential and not yet answered question is how mitochondria surrounding the karyoplast will be distributed in the newly reconstructed oocytes. In our model experiments, we have evaluated the dis...
متن کاملEffect of Ethanol on Maturation and Development of Immatur Mouse Oocytes
Purpose: To study the effect of ethanol on resumption of meiosis, maturation and development of immature mouse oocytes in vitro. Materials and Methods: Immature oocytes were dissected from ovary of NMRI strain mouse (6-8 weeks old) and divided into control and experimental groups. The absolute ethanol was imposed to oocytes at doses of 0 (Control), 0.05, 0.1, 0.2 and 0.4% (v/v) in maturation c...
