Errors in chromosome segregation during oogenesis and early embryogenesis [PDF]

open access: yes, 2010
Errors in chromosome segregation occurring during human oogenesis and early embryogenesis are very common. Meiotic chromosome development during oogenesis is subdivided into three distinct phases.

Transcriptomic and functional analyses of the piRNA pathway in the Chagas disease vector Rhodnius prolixus.

open access: yesPLoS Neglected Tropical Diseases, 2018
The piRNA pathway is a surveillance system that guarantees oogenesis and adult fertility in a range of animal species. The pathway is centered on PIWI clade Argonaute proteins and the associated small non-coding RNAs termed piRNAs.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

LOTUS domain protein MARF1 binds CCR4-NOT deadenylase complex to post-transcriptionally regulate gene expression in oocytes

open access: yesNature Communications, 2018
The RNA-binding protein MARF1 is required for post-transcriptional regulation of mRNAs during mouse oogenesis. Here, by analyzing a Drosophila MARF1 mutant, the authors show that MARF1 recruits CCR4-NOT deadenylase to shorten the poly-A tails of target ...

A spatiotemporal single‐cell atlas of porcine development reveals regulatory dynamics and cellular targets of domestication

open access: yesiMeta, EarlyView.
This study presents a cross‐tissue, single‐cell/single‐nucleus transcriptomic atlas spanning from prenatal to postnatal developmental stages in pig, characterizing 83 distinct cell types from 252,033 cells. Through the construction of cross‐tissue transcriptional regulatory networks and pseudotime trajectories, we revealed that organogenesis is driven ...

A Single‐Cell Atlas of Crab Ovary Provides New Insights Into Oogenesis in Crustaceans

open access: yesAdvanced Science
Oogenesis is crucial for sexual reproduction and provides the material basis for population continuation. Nonetheless, the identity of the cells involved, the nature of transformation, and underlying regulators of oogenesis in crustaceans remain elusive.

The Role of Mitochondria in Human Fertility and Early Embryo Development: What Can We Learn for Clinical Application of Assessing and Improving Mitochondrial DNA?

open access: yesCells, 2022
Mitochondria are well known as ‘the powerhouses of the cell’. Indeed, their major role is cellular energy production driven by both mitochondrial and nuclear DNA.

Toxic Effects of Bisphenol A and Its Analogs on Ovarian Structure and Function: A Narrative Review of Ovary‐Focused Studies

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is a widely used industrial chemical found in polycarbonate plastics and epoxy resins and is recognized for its endocrine‐disrupting properties. Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE

Oogenesis in Caenorhabditis elegans

open access: yesSexual Development, 2023
Background: The nematode, Caenorhabditis elegans has proven itself as a valuable model for investigating metazoan biology. C. elegans have a transparent body, an invariant cell lineage, and a high level of genetic conservation which makes it a desirable model organism.

Role of Endocrine System in the Regulation of Female Insect Reproduction

open access: yesBiology, 2021
The proper synthesis and functioning of ecdysteroids and juvenile hormones (JHs) are very important for the regulation of vitellogenesis and oogenesis.
