Interação YAP1-TEAD regula a cascata de sinalização do EGF em células do cumulus em bovinos
(Universidade Federal de Santa MariaBrasilMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina VeterináriaCentro de Ciências Rurais, 2020-02-07)
The mechanism of cumulus cell (CC) expansion and ovulation in vivo is triggered by LH surge in granulosa cells and CC, which culminating in a series of paracrine and autocrine communications between these ovarian cells. ...
Fibroblast growth factor 2 regulates cumulus differentiation under the control of the oocyte
(Springer, 2019-05-01)
PurposeWe first assessed regulation of FGF2 expression in cumulus cells by FSH and oocyte-secreted factors during in vitro maturation (IVM). Then, we tested the hypothesis that FGF2 regulates meiotic progression, cumulus ...
Cumulus cell apoptosis changes with exposure to spermatozoa and pathologies involved in infertility
(2009)
Objective: To determine whether the incidence of apoptosis in mature oocyte cumulus cells changes after insemination related to infertility. Design: Prospective study. Setting: Public hospital and university. Patient(s): ...
The importance of manganese in the cytoplasmic maturation of cattle oocytes: blastocyst production improvement regardless of cumulus cells presence during in vitro maturation
(Cambridge University Press, 2016-02)
Adequate dietary intake of manganese (Mn) is required for normal reproductive performance in cattle. This study was carried out to investigate the effect of Mn during in vitro maturation of bovine cumulus–oocyte complexes ...
Time course of the meiotic arrest in sheep cumulus-oocyte complexes treated with roscovitine
(Cambridge University Press, 2015)
Temporary meiosis arrest with cyclin-dependent kinases inhibitors has been proposed in order to improve the quality of in vitro matured oocytes. In sheep, however, this phenomenon has been rarely investigated. Therefore, ...
The importance of having zinc during in vitro maturation of cattle Cumulus–Oocyte complex: role of Cumulus cells
(Wiley VCH Verlag, 2014-10)
The aim of this study was to investigate the influence of zinc (Zn) on the health of cumulus–oocyte complex (COC) during in vitro maturation (IVM). Experiments were designed to evaluate the effect of Zn added to IVM medium ...
Effect of melatonin on in vitro maturation of bovine cumulus-oocyte complexes and DNA damage of cumulus cells
(Wiley-Blackwell Publishing, Inc, 2008-07-01)
Effect of melatonin on in vitro maturation of bovine cumulus-oocyte complexes and DNA damage of cumulus cells
(Wiley-Blackwell Publishing, Inc, 2008-07-01)
Follicular environment and oocyte maturation: roles of local peptides and steroids
(Brazilian Coll Animal Reproduction, 2017-07-01)
A large amount of data on the mechanisms regulating cumulus-oocyte maturation in mammals has been generated in the last 20 years. It has been made clear that oocyte-secreted factors play a central role in the control of ...
