Biallelic MAD2L1BP variants contribute to oocyte metaphase I arrest in women with primary infertility and p31comet is required for human oocyte maturation.
Oocyte maturation and ovulation in the sister group of vertebrates, Ciona intestinalis Type A, are triggered by Ci-VP, the Ciona homolog of a typical neruopeptide, vasopressin.
A whole-genome genetic screen links new aspects of oocyte maturation to proteostasis renewal in the immortal Caenorhabditis elegans germ-cell lineage and reveals similarities to somatic cell maintenance during aging.
Gamete release in the jellyfish Clytia is mediated by an opsin photopigment expressed in neurosecretory cells of the gonad ectoderm, which release an oocyte maturation hormone in response to light.
In vitro and in vivo data show that C-natriuretic peptide is significant for increasing mitochondrial bioenergetics by cAMP-PKA pathway and improving cytoplasmic and nuclear maturation of maternally aged oocyte.

Profiling of mRNA poly(A)-tail lengths and translational efficiencies provides new insights into posttranscriptional gene regulation in early Drosophila development.
FMNL2 associates with Formin2 and Arp2/3 complex for actin assembly, which further regulates spindle migration and INF2/Cofilin-related organelle dynamics during mammalian oocyte maturation.

Meiotic chromosome segregation in mature Drosophila oocytes is sensitive to prolonged quiescence, suggesting that human oocyte instability may result from storage of mature rather than primordial oocytes and be modifiable.
