HLA-G MOLECULES: FROM EMBRYO IMPLANTATION TO OOCYTE MATURATION [PDF]

open access: yes, 2009
Background Assisted reproduction technique (ART) pregnancy rates have not changed in recent years and an increased risk of twins, triplets or higher order pregnancies leads to a perinatal mortality and morbidity.

Single Ca2+ transients vs oscillatory Ca2+ signaling for assisted oocyte activation : limitations and benefits [PDF]

open access: yes, 2018
Oocyte activation is a calcium (Ca2+)-dependent process that has been investigated in depth, in particular, regarding its impact on assisted reproduction technology (ART).

Characterization and therapy of fertilization failure in murine and human models with HNRNPR mutations

open access: yesEMBO Molecular Medicine
Oocyte activation is essential for successful fertilization and subsequent embryonic development. However, only a few disease-causing genes have been associated with sperm-derived oocyte activation failure, and the underlying molecular mechanisms and ...

Mechanisms of oocyte activation in the presence and absence of PLCζ [PDF]

open access: yes, 2022
Mammalian oocyte activation is thought to be caused by a sperm borne PLC subtype, called phospholipase C zeta1 (PLCζ). PLCζ RNA and protein microinjection and knockout studies in a mouse model have confirmed its primary role in releasing calcium (Ca2 ...

Stage‐Specific H3K14 and H3K23 Succinylation Orchestrates Insect Metamorphosis and Oogenesis

open access: yesAdvanced Science, EarlyView.
Stage‐specific succinylation of histone H3 at lysine 14 and 23 differentially controls insect metamorphosis and oogenesis through distinct GPCR‐PKC signaling cascades, revealing an evolutionarily conserved epigenetic mechanism that coordinates key life‐history traits.

Evaluation of different factors affecting the efficiency of oocytes cryopreservation in the bovine model [PDF]

open access: yes, 2011
Interest in oocyte cryopreservation has recently increased. Cattle oocytes are sensitive to low temperatures, and despite the efforts of numerous research groups cryopreservation of oocytes remains a difficult task.

Artificial oocyte activation: evidence for clinical readiness [PDF]

open access: yes, 2016
Artificial oocyte activation using Ca2+ionophores or similar compounds is a widely applied technique in IVF laboratories. This is all the more interesting as most of the agents aiming for intracellular Ca2+ increase do not result in physiological Ca2 ...
