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.

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.

Impact of Maternal Age on Oocyte and Embryo Competence
Frontiers in Endocrinology, 2018 The overall success of human reproduction, either spontaneously or after IVF, is highly dependent upon maternal age. The main reasons for age-related infertility include reduced ovarian reserve and decreased oocyte/embryo competence due to aging insults,

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.

Molecules and Cells, 2017 Summary YTHDF2 binds and destabilizes N6-methyladenosine (m6A)-modified mRNA. The extent to which this branch of m6A RNA-regulatory pathway functions in vivo and contributes to mammalian development remains unknown. Here we find that YTHDF2 deficiency is

GGPP-Mediated Protein Geranylgeranylation in Oocyte Is Essential for the Establishment of Oocyte-Granulosa Cell Communication and Primary-Secondary Follicle Transition in Mouse Ovary. [PDF]
PLoS Genetics, 2017 Folliculogenesis is a progressive and highly regulated process, which is essential to provide ova for later reproductive life, requires the bidirectional communication between the oocyte and granulosa cells.

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.
