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.

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.

Characterization of the Drosophila Egfl7/8 ortholog during oogenesis [PDF]

, 2006
During animal development precise coordination and regulation of cell proliferation, differentiation and cell death is required for proper tissue organization. This is achieved through specific cell communication by intercellular signals. Cell death, for

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

RNAi-based screens uncover a potential new role for the orphan neuropeptide receptor Moody in Drosophila female germline stem cell maintenance.

PLoS ONE, 2020
Reproduction is highly sensitive to changes in physiology and the external environment. Neuropeptides are evolutionarily conserved signaling molecules that regulate multiple physiological processes.

LSM14B is an Oocyte‐Specific RNA‐Binding Protein Indispensable for Maternal mRNA Metabolism and Oocyte Development in Mice

Advanced Science, 2023
Mammalian oogenesis features reliance on the mRNAs produced and stored during early growth phase. These are essential for producing an oocyte competent to undergo meiotic maturation and embryogenesis later when oocytes are transcriptionally silent.

Drosophila p53 isoforms have overlapping and distinct functions in germline genome integrity and oocyte quality control

eLife, 2022
p53 gene family members in humans and other organisms encode a large number of protein isoforms whose functions are largely undefined. Using Drosophila as a model, we find that a p53B isoform is expressed predominantly in the germline where it ...

Select aspects of oogenesis and folliculogenesis

, 2013
The processes of oogenesis and folliculogenesis begin very early in foetal life and are continued until the end of the reproductive period. Despite the numerous research conducted, the mechanism which initiates the growth of primary follicles has not ...
