The limited knowledge on the regulation of oocyte formation, the different steps of
folliculogenesis and the required conditions for oocytes to undergo proper growth …

The mitogen-activated protein kinase (MAPK) cascade is one of the most important of the
intracellular signaling pathways that play a crucial role in cell proliferation, cell differentiation …

Mitogen-activated protein kinase (MAPK) is a family of Ser/Thr protein kinases that are
widely distributed in eukaryotic cells. Studies in the last decade revealed that MAPK …

This study investigated the participation of MAPK in the resumption of meiosis [germinal
vesicle breakdown (GVB)] in oocytes and cumulus expansion using oocyte-cumulus cell …

Dietary polyunsaturated fatty acids can influence reproductive performance. In dairy cattle,
some high-fat diets resulted in higher blastocyst rates and improved embryo quality. These …

Oocyte meiotic maturation is one of the important physiological requirements for species
survival. However, little is known about the detailed events occurring during this process. A …

BACKGROUND During meiosis, mammalian oocytes undergo two successive cell divisions
without an intermediate replicative phase. This brief period, called 'meiotic maturation', is …

The developmental competence of bovine oocytes isolated from antral follicles of different
sizes was assessed in three European laboratories (Belgium, UCL; Denmark, DIAS; France …

Our previous studies have shown that oocytes collected from prepubertal calves lack
developmental competence. The overall objective of this study was to assess causes by …

In this study, butyrolactone I (BL I), a potent and specific inhibitor of cyclin-dependent
kinases, was shown to block germinal vesicle (GV) breakdown (GVBD) in bovine oocytes in …
