Cyclic nucleotide in oocyte In vitro maturation in Assisted Reproductive Technology

Journal of Biomedicine and Translational Research, 2020
In vitro maturation (IVM) is a promising assisted reproductive technology (ART) for human infertility treatment. However, when cumulus oocyte complexes (COCs) are removed from their follicular environment when manipulated in vitro, it can lead to a ...

Mutations in CCNB3 affect its location thus causing a multiplicity of phenotypes in human oocytes maturation by aberrant CDK1 activity and APC/C activity at different stages

Journal of Ovarian Research, 2023
Background Oocyte maturation arrest results in female infertility and the genetic etiology of this phenotype remains largely unknown. Previous studies have proven that cyclins play a significant role in the cell cycle both in meiosis and mitosis.

PATL2 is a key actor of oocyte maturation whose invalidation causes infertility in women and mice

EMBO Molecular Medicine, 2018
The genetic causes of oocyte meiotic deficiency (OMD), a form of primary infertility characterised by the production of immature oocytes, remain largely unexplored.

A novel role for DNA methyltransferase 1 in regulating oocyte cytoplasmic maturation in pigs.

PLoS ONE, 2015
Maternal factors are required for oocyte maturation and embryo development. To better understand the role of DNA methyltransferase 1 (Dnmt1) in oocyte maturation and embryo development, small interfering RNA (siRNA) was conducted in porcine oocytes.

BPA-Induced Deregulation of Epigenetic Patterns: Effects on Female Zebrafish Reproduction [PDF]

, 2016
Bisphenol A (BPA) is one of the commonest Endocrine Disruptor Compounds worldwide. It interferes with vertebrate reproduction, possibly by inducing deregulation of epigenetic mechanisms.

Human oocyte maturation in vitro

The International Journal of Developmental Biology, 2012
Oocytes from medium-sized antral follicles have already completed their growth phase and, if released from the follicular environment and cultured in vitro, are able to resume the meiotic process and mature. However, in vitro maturation (IVM) does not entirely support all the nuclear and cytoplasmic changes that occur physiologically as an effect of ...

Chromosome transfer in mature oocytes [PDF]

Fertility and Sterility, 2010
In this article, we describe detailed protocols for the isolation and transfer of spindle-chromosomal complexes between mature, metaphase II-arrested oocytes. In brief, the spindle-chromosomal complex is visualized using a polarized microscope and extracted into a membrane-enclosed karyoplast.

Supplementation of rapamycin during in vitro maturation promotes oocyte quality and subsequent embryo development in bovine

Bulletin of the National Research Centre, 2023
Background The developmental competence of oocyte derived from in vitro maturation (IVM) is significantly lower than those of oocyte matured in vivo. Rapamycin is an immunosuppressive substance and widely used to prolong the survival and preserve the ...
