Angiotensin II, progesterone, and prostaglandins are sequential steps in the pathway to bovine oocyte nuclear maturation
(Elsevier B.V., 2012-06-01)
Oocyte meiotic resumption is triggered by the ovulatory gonadotropin surge; in cattle, angiotensin II (AngII) and prostaglandins (PG) are key mediators of this gonadotropin-induced event. Here, we tested the hypothesis ...

Meiotic inhibition of bovine oocytes in medium supplemented with a serum replacer and hormones: effects on meiosis progression and developmental capacity
(Cambridge University Press, 2011-05-01)
Aiming to improve the developmental competence of bovine oocytes during meiotic block, this study evaluated the effects of a serum replacer (Knockout SR(R)) and hormones (gonadotropins and estradiol) supplementation of ...

Delaying meiotic resumption during transportation of bovine cumulus-oocyte complexes: Effects on development, apoptosis and caspases activity of in vitro-produced embryos
(2017-12-01)
This study examined the effects of meiosis inhibition during bovine oocyte transportation on developmental competence and quality of produced embryos. The transportation medium was supplemented with: 100 μM butyrolactone ...
Função da ocitocina na indução da retomada meiótica de oócitos em bovinos
(Universidade Federal de Santa MariaBRFarmacologiaUFSMPrograma de Pós-Graduação em Farmacologia, 2011-10-31)
The aim of the present study was to examine the role of oxytocin (OT) on the control of oocyte meiotic resumption in the events that involves progesterone (P4) and prostaglandins (PGs). Oocytes were co-cultured with ...
Treatment with roscovitine and butyrolactone i prior to in vitro maturation alters blastocyst production
(2019-01-01)
SummaryThis study evaluated the effects of oocyte meiosis inhibitors roscovitine (ROS) and butyrolactone I (BL-I) on in vitro production of bovine embryos. Bovine oocytes were maintained in pre in vitro maturation (pre-IVM) ...
Modulação do reinício da meiose de oócitos bovinos pelo fator de crescimento fibroblástico 10, angiotensina II e progesterona em sistema alternativo de cultivo
(Universidade Federal de Santa MariaBRMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina Veterinária, 2009-02-27)
The aim of this study was to evaluate the effect of fibroblast growth factor 10 (FGF10) on bovine oocyte meiotic resumption in an in vitro oocyte and follicular cells co-culture system. At first, an oil-free culture system ...
Meiotic maturation of amphibian oocytes increases dephosphorylation of microinjected histones.
(Academic Pres Australia, 1981)
Histone H2b phosphorylated by a cAMP dependent protein kinase was injected into Xenopus laevis oocytes and the hydrolysis of phosphate groups measured. Two hours after injection 60% of the (32p) histone radioactivity had ...
