Cell Reports, 2022 Summary: Inactivation of cyclin-dependent kinase 1 (Cdk1), controlled by cyclin B1 proteolysis, orders events during mitotic exit. Here, we used a FRET biosensor to study Cdk1 activity while simultaneously monitoring anaphase II and pronuclear (PN ...

mRNA active transport in oocyte-early embryo: 3D agent-based modeling [PDF]
arXiv, 2023 Axes of polarity (and primary morphogenetic gradients) are established in the oocyte - early embryo through active transport and localization of maternal factors. It is the oocyte - syncytial embryo of Drosophila (D. melanogaster) that is a model object for studying the molecular machinery of such transport systems.

Impact of Oxidative Stress on Age-Associated Decline in Oocyte Developmental Competence
Frontiers in Endocrinology, 2019 Reproductive capacity in women starts to decline beyond their mid-30s and pregnancies in older women result in higher rates of miscarriage with aneuploidy.

Ultrafast imaging of cell elasticity with optical microelastography [PDF]
PNAS January 18, 2018. 201713395, 2018 Elasticity is a fundamental cellular property that is related to the anatomy, functionality and pathological state of cells and tissues. However, current techniques based on cell deformation, atomic force microscopy or Brillouin scattering are rather slow and do not always accurately represent cell elasticity.

Reorganization, specialization, and degradation of oocyte maternal components for early development
Reproductive Medicine and Biology, 2023 Background Oocyte components are maternally provided, solely determine oocyte quality, and coordinately determine embryo quality with zygotic gene expression.

Obesity Induces Ovarian Inflammation and Reduces Oocyte Quality.
Reproduction, 2019 In the US, 36.5 percent of women between the ages of 20-39 are obese. This obesity results in not only metabolic disorders including type II diabetes and cardiovascular disease, but also impaired female fertility.

Aspects of follicular and oocyte maturation that affect the developmental potential of embryos.
Journal of reproduction and fertility. Supplement, 2019 The ability to mature, be fertilized and finally to develop into a viable embryo is acquired gradually by the oocyte during progressive differentiation throughout folliculogenesis.
