Abstract: Epigenetic mechanisms are thought to be involved in the reduced developmental capacity of early prepubertal ewe oocytes compared to their adult counterparts. In this study, we have analyzed the global DNA methylation pattern and in vitro… read more here.

27 Vitrification at the germinal vesicle stage does not trigger apoptosis in porcine oocytes and early embryos

DOI: 10.1071/rdv32n2ab27
Abstract: Porcine immature oocytes can survive vitrification at high rates and retain their ability to undergo maturation and fertilization; however, the procedure reduces their competence for subsequent embryo development via unknown mechanisms (Somfai et al. 2014… read more here.

Abstract: AbstractThe size of oocytes during germinal vesicle migration (GVM) and germinal vesicle breakdown (GVBD) was revised for the Leopard Grouper Mycteroperca rosacea. Histology of ovaries, plasma levels of estradiol-17s (E2), and testosterone (T) were analyzed… read more here.

DOI: 10.7717/peerj.3032
Abstract: Calcineurin (CN) is a serine/threonine phosphatase which plays important roles in meiosis maturation in invertebrate oocytes; however, the role of CN in mouse oocytes is relatively unexplored. In this study, we examined the expression, localization… read more here.
