Peptides in insect oogenesis [PDF]

Current Opinion in Insect Science, 2019
© 2018 Elsevier Inc. The physiological control of reproduction in insects depends on a combination of environmental and internal cues. In the adult stage, insects become sexually mature and generate gametes.

Unscrambling butterfly oogenesis [PDF]

BMC Genomics, 2013
Background: Butterflies are popular model organisms to study physiological mechanisms underlying variability in oogenesis and egg provisioning in response to environmental conditions.

Oogenesis: Matrix Revolutions [PDF]

Current Biology, 2011
SummaryThe mechanism of egg-chamber elongation during Drosophila oogenesis has always been mysterious. A new study shows that the egg chambers spin around their long axis laying down polarised extracellular matrix, which acts as a molecular corset to ...

The dynamic landscape of gene regulation during Bombyx mori oogenesis

BMC Genomics, 2017
Background Oogenesis in the domestic silkworm (Bombyx mori) is a complex process involving previtellogenesis, vitellogenesis and choriogenesis. During this process, follicles show drastic morphological and physiological changes.

Neo-oogenesis in mammals

Zygote, 2017
SummaryRecently, the existence of a mechanism for neo-oogenesis in the ovaries of adult mammals has generated much controversy within reproductive biology. This mechanism, which proposes that the ovary has cells capable of renewing the follicular reserve,

Molecular control of oogenesis

Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2012
Oogenesis is a complex process regulated by a vast number of intra- and extra-ovarian factors. Oogonia, which originate from primordial germ cells, proliferate by mitosis and form primary oocytes that arrest at the prophase stage of the first meiotic ...

Germ cell-intrinsic effects of sex chromosomes on early oocyte differentiation in mice.

PLoS Genetics, 2020
A set of sex chromosomes is required for gametogenesis in both males and females, as represented by sex chromosome disorders causing agametic phenotypes. Although studies using model animals have investigated the functional requirement of sex chromosomes,

Sequential Regulation of Maternal mRNAs through a Conserved cis-Acting Element in Their 3′ UTRs

Cell Reports, 2018
Summary: Maternal mRNAs synthesized during oogenesis initiate the development of future generations. Some maternal mRNAs are either somatic or germline determinants and must be translationally repressed until embryogenesis.

Ablation of the MiR-17-92 MicroRNA Cluster in Germ Cells Causes Subfertility in Female Mice

Cellular Physiology and Biochemistry, 2018
Background/Aims: Oogenesis is a highly complex process that is intricately regulated by interactions of multiple genes and signaling molecules. However, the underlying molecular mechanisms are poorly understood.

High-dose irradiation induces cell cycle arrest, apoptosis, and developmental defects during Drosophila oogenesis. [PDF]

PLoS ONE, 2014
Ionizing radiation (IR) treatment induces a DNA damage response, including cell cycle arrest, DNA repair, and apoptosis in metazoan somatic cells. Because little has been reported in germline cells, we performed a temporal analysis of the DNA damage ...
