Schematic of NC chromatin states during Drosophila oogenesis.
, 2013 (A) Early oogenesis (up to stage 1) marks the formation and budding of the egg chamber from the germarium. The 16-cell syncytium arises from 4 mitotic divisions with incomplete cytokinesis; one cell becomes an oocyte which arrests during meiotic prophase

Implications of Maternal Toxicant Effects on Size‐Dependent Fisheries' Management: A Meta‐Analysis
Fish and Fisheries, Volume 27, Issue 4, Page 895-911, July 2026.Larger, older fish transfer higher mercury and PCB concentrations to their eggs, significantly reducing offspring hatching success, survival and growth rates in contaminated aquatic ecosystems. These findings suggest that the reproductive benefits of big old fat fecund female fish may be compromised by maternal toxicant transfer in polluted waters ...

[Is neo-oogenesis in the adult ovary, a realistic paradigm?]
, 2010 International audienceIt is a central dogma of female reproductive biology that oogenesis ceases around the time of birth in mammalian species. In 2004 and 2005, two studies were published by Johnson et al., in which they claimed that in the adult mouse ...

FEBS Open Bio, Volume 16, Issue 6, Page 1087-1101, June 2026.dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

, 2011 RNA localization is a cellular mechanism used to localize proteins to sub-cellular domains and to control protein synthesis regionally. In oocytes, RNA localization has profound implications for development, generating asymmetric protein distributions ...

Expression of cell-cycle regulators during Xenopus oogenesis [PDF]
, 2003 In full-grown Xenopus oocytes, cell-cycle regulators and an inactive form of maturation/M phase promoting factor (pre-MPF) are stored ready to bring about a specific cell cycle for oocyte maturation. We examined the expression pattern of these cell-cycle

Novel roles for ecdysone receptor in the Drosophila germline
, 2023 Oogenesis, the process by which a viable egg is produced, demands carefully coordinated communication between somatic and germ cell populations, relying on both local and systemic factors such as steroid hormones for signaling. In Drosophila, the steroid

BMC Genetics, 2003 Background Differential methylation of the two alleles is a hallmark of imprinted genes. Correspondingly, loss of DNA methyltransferase function results in aberrant imprinting and abnormal post-fertilization development.
