Single-Cell Atlas of the Chinese Tongue Sole (Cynoglossus semilaevis) Ovary Reveals Transcriptional Programs of Oogenesis in Fish

Frontiers in Cell and Developmental Biology, 2022
Oogenesis is a highly orchestrated process that depends on regulation by autocrine/paracrine hormones and growth factors. However, many details of the molecular mechanisms that regulate fish oogenesis remain elusive.

Murder on the Ovarian Express: A Tale of Non-Autonomous Cell Death in the Drosophila Ovary

Cells, 2021
Throughout oogenesis, Drosophila egg chambers traverse the fine line between survival and death. After surviving the ten early and middle stages of oogenesis, egg chambers drastically change their size and structure to produce fully developed oocytes ...

Generation and Characterization of Germline-Specific Autophagy and Mitochondrial Reactive Oxygen Species Reporters in Drosophila

Frontiers in Cell and Developmental Biology, 2019
Oogenesis is a fundamental process that forms the egg and, is crucial for the transmission of genetic information to the next generation. Drosophila oogenesis has been used extensively as a genetically tractable model to study organogenesis, niche ...

Sexual and asexual oogenesis require the expression of unique and shared sets of genes in the insect Acyrthosiphon pisum

BMC Genomics, 2012
Background Although sexual reproduction is dominant within eukaryotes, asexual reproduction is widespread and has evolved independently as a derived trait in almost all major taxa. How asexuality evolved in sexual organisms is unclear.

E-cadherin acts as a positive regulator of the JAK-STAT signaling pathway during Drosophila oogenesis

Frontiers in Cell and Developmental Biology, 2022
The JAK-STAT pathway is evolutionary conserved. The simplicity of this signaling in Drosophila, due to the limited redundancy between pathway components, makes it an ideal model for investigation.

Regulation of Drosophila Oogenesis by Neuropeptide Signaling [PDF]

, 2021
Reproduction, particularly in females, is very energy-expensive, and organisms must balance survival and reproductive success. Therefore, oogenesis is highly regulated by whole-body physiology.

A developmental stage-specific switch from DAZL to BOLL occurs during fetal oogenesis in humans, but not mice.

PLoS ONE, 2013
The Deleted in Azoospermia gene family encodes three germ cell-specific RNA-binding proteins (DAZ, DAZL and BOLL) that are essential for gametogenesis in diverse species.

Ovary Structure and Oogenesis of Trypophloeus klimeschi (Coleoptera: Curculionidae: Scolytinae)

Insects, 2021
The female reproductive system, ovary structure and ultrastructure of Trypophloeus klimeschi (Coleoptera: Curculionidae: Scolytinae) were investigated using light microscopy, scanning electron microscopy, and transmission electron microscopy.

Stem cells in the ovary [PDF]

, 2009
For decades, scientists have thought that female mammals are born with a lifetime supply of oocytes in the ovary, irreversibly destined to decline after birth.

Subcellular localization and Egl-mediated transport of telomeric retrotransposon HeT-A ribonucleoprotein particles in the Drosophila germline and early embryogenesis. [PDF]

PLoS ONE, 2018
The study of the telomeric complex in oogenesis and early development is important for understanding the mechanisms which maintain genome integrity. Telomeric transcripts are the key components of the telomeric complex and are essential for regulation of
