FSH-Induced Nuclear Exclusion of FOXO1 Mediated by PI3K/Akt Signaling Pathway in Granulosa Cells Is Associated with Follicle Selection and Growth of the Hen Ovary [PDF]
CellsFollicle selection is a pivotal process that determines which dominant prehierarchical follicle will enter the preovulatory hierarchy in the hen ovary and directly affects egg-laying productivity, in which granulosa cells (GCs) are characterized by ...

CircRNAs involved in the red light of effect on follicle selection in pigeons [PDF]
Poultry Science: Red light (RL) can enhance egg production in poultry. CircRNAs play a crucial role by serving as transcriptional regulators. However, their role in influencing follicle development in White King pigeons remains unexplored.

Oocyte-derived microvilli control female fertility by optimizing ovarian follicle selection in mice [PDF]
Nature Communications, 2021 How structural features on oocytes regulate mammalian female reproduction is unclear. Here, the authors provide imaging and physiological evidence (for example on Radixin knockout) to identify oocyte-derived mushroom-like microvilli that control the ...

Combined transcriptome and metabolome analysis of chicken follicles in Tengchong Snow Chicken follicle selection. [PDF]
Anim BiosciObjective: The development of pre-hierarchical follicles (PHFs), especially small yellow follicles (SYFs), directly affects the recruitment of dominant follicles and subsequently affects the egg-laying performance of chickens. The development of PHFs, especially SYFs, and their regulatory mechanisms remain unclear.Methods: Transcriptomic and ...

Ovarian Follicle Selection and Granulosa Cell Differentiation
Poultry Science, 2015 The reproductive strategy for avian species that produce a sequence (or clutch) of eggs is dependent upon the maintenance of a small cohort of viable, undifferentiated (prehierarchal) follicles. It is from this cohort that a single follicle is selected on an approximate daily basis to initiate rapid growth and final differentiation before ovulation ...
