Fertility loss: negative effects of environmental toxicants on oogenesis
Frontiers in Physiology, 2023 There has been a global decline in fertility rates, with ovulatory disorders emerging as the leading cause, contributing to a global lifetime infertility prevalence of 17.5%.

EMBO Journal, 2023 In most metazoans, centrioles are lost during oogenesis, ensuring that the zygote is endowed with the correct number of two centrioles, which are paternally contributed. How centriole architecture is dismantled during oogenesis is not understood.

Systemic Regulation of Host Energy and Oogenesis by Microbiome-Derived Mitochondrial Coenzymes
Cell Reports, 2021 Gut microbiota have been shown to promote oogenesis and fecundity, but the mechanistic basis of remote influence on oogenesis remained unknown. Here, we report a systemic mechanism of influence mediated by bacterial-derived supply of mitochondrial ...

Nuclear Pores Assemble from Nucleoporin Condensates During Oogenesis
Cell, 2019 Summary The molecular events that direct nuclear pore complex (NPC) assembly toward nuclear envelopes have been conceptualized in two pathways that occur during mitosis or interphase, respectively.

Hijacking Oogenesis Enables Massive Propagation of LINE and Retroviral Transposons
Cell, 2018 SUMMARY Although animals have evolved multiple mechanisms to suppress transposons, “leaky” mobilizations that cause mutations and diseases still occur. This suggests that transposons employ specific tactics to accomplish robust propagation.

Myosin VI is expressed in developing ovarian follicles in Drosophila but is not essential for effective oogenesis [PDF]
Frontiers in Cell and Developmental BiologyMyosin VI is the only actin-based motor known to move toward the minus end of actin filaments. This protein is involved in many different cellular processes, such as endocytosis, autophagy, secretion, and regulation of actin organization and dynamics ...

Stage Specific Transcriptomic Analysis and Database for Zebrafish Oogenesis
Frontiers in Cell and Developmental Biology, 2022 Oogenesis produces functional eggs and is essential for fertility, embryonic development, and reproduction. The zebrafish ovary is an excellent model to study oogenesis in vertebrates, and recent studies have identified multiple regulators in oocyte ...

Microinjection Method for Analyzing Zebrafish Early Stage Oocytes
Frontiers in Cell and Developmental Biology, 2021 Maternal factors which accumulate and establish oocyte polarity during the early stages of oogenesis play key roles in embryonic development, as well as germ cell formation. However, vertebrate oogenesis, especially early stages of oogenesis, is not well

Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Metazoan species optimize the timing of reproduction to maximize fitness. To understand how biological clocks direct reproduction, we investigated the neural substrates that produce oogenesis rhythms in the genetically amenable model ...

Prp22 and spliceosome components regulate chromatin dynamics in germ-line polyploid cells. [PDF]
PLoS ONE, 2013 During Drosophila oogenesis, the endopolyploid nuclei of germ-line nurse cells undergo a dramatic shift in morphology as oogenesis progresses; the easily-visible chromosomes are initially polytenic during the early stages of oogenesis before they ...
