Control of pluripotency during the oocyte-to-embryo transition in caenorhabditis elegans [PDF]
, 2015 The germline of Caenorhabditis elegans has been used as a model system to study the control of pluripotency in germ cells: through the mean of a genetic screen, from which most of the results of this thesis derived, different factors involved in the ...

The Journal of Reproduction and Development, 2023 The mechanisms underlying postovulatory oocyte aging (POA) remain largely unknown. The expression of the calcium-sensing receptor (CaSR) in mouse oocytes and its role in POA need to be explored.

Deep evolutionary conservation of an intramolecular protein kinase activation mechanism [PDF]
, 2012 DYRK-family kinases employ an intramolecular mechanism to autophosphorylate a critical tyrosine residue in the activation loop. Once phosphorylated, DYRKs lose tyrosine kinase activity and function as serine/threonine kinases.

Freezing the Biological Clock: A Viable Fertility Preservation Option for Young Singaporean Women? [PDF]
, 2013 In March 2012, an article in The Straits Times entitled ‘Freezing eggs could reverse falling birth rate’ suggested that employing the latest oocyte cryopreservation techniques could both foster individual women’s reproductive autonomy and impact ...

eLife, 2017 The oocyte-to-embryo transition involves extensive changes in mRNA translation, regulated in Drosophila by the PNG kinase complex whose activity we show here to be under precise developmental control. Despite presence of the catalytic PNG subunit and the

Stimulation of TRPV1 by green laser light [PDF]
, 2012 Low-level laser irradiation of visible light had been introduced as a medical treatment already more than 40 years ago, but its medical application still remains controversial.

Role of Na+/Ca2+ exchanger (NCX) in modulating postovulatory aging of mouse and rat oocytes.
PLoS ONE, 2014 We studied the role of the Na+/Ca2+ exchanger (NCX) in modulating oocyte postovulatory aging by observing changes in NCX contents and activities in aging mouse and rat oocytes.

Sperm Originated Chromatin Imprints and LincRNAs in Organismal Development and Cancer
iScience, 2020 Summary: Importance of sperm-derived transcripts and chromatin imprints in organismal development is poorly investigated. Here using an integrative approach, we show that human sperm transcripts are equally important as oocyte.

Animal, 2023 The oocyte is the basis of life, supporting development from a fertilized cell to an independent multicellular organism. The oocyte’s competence to drive the first cell cycles postfertilization are critical to embryonic survival and subsequent successful

Zinc Dynamics during Drosophila Oocyte Maturation and Egg Activation
iScience, 2020 Summary: Temporal fluctuations in zinc concentration are essential signals, including during oogenesis and early embryogenesis. In mammals, zinc accumulation and release are required for oocyte maturation and egg activation, respectively.
