FMR1 expression in human granulosa cells increases with exon 1 CGG repeat length depending on ovarian reserve [PDF]
Background: Fragile-X-Mental-Retardation-1- (FMR1)-gene is supposed to be a key gene for ovarian reserve and folliculogenesis. It contains in its 5’-UTR a triplet-base-repeat (CGG), that varies between 26 and 34 in general population.

Maternal TCF12 ensures the competence of fertilisation by controlling the expression of Astl and the proper location of cortical granules. Furthermore, maternal TCF12 maintains the phosphatase activity of PP2A by regulating the expression of Arpp19. Oocyte‐specific deletion of Tcf12 leads to fertilisation defects as well as ZGA failure at the 2‐cell ...

ABSTRACT The greater rhea (Rhea americana), the largest bird species in South America, has significant economic value due to its meat, eggs, leather, feathers and oil. However, its lack of external sexual dimorphism poses challenges for reproductive management and breeding programmes.

Folliculogenesis: A Cellular Crosstalk Mechanism
In vitro embryo production has accelerated in the cattle industry in recent years. Because women are similar to cows, this represents an opportunity to improve women’s reproductive protocols. This review focuses on crosstalk communication during folliculogenesis for an in-depth understanding of the events involved in developing the oocyte competence ...

A schematic showing decreased PTGES2 farnesylation in granulosa cells compromises PGE2‐dependent cumulus expansion and oocyte maturation during ovarian aging. In young ovaries, PTGES2 farnesylation of GCs regulates the process of cumulus expansion and oocyte maturation by facilitating PGE2 production.

Molecular basis of oocyte-paracrine signalling that promotes granulosa cell proliferation [PDF]
Copyright © 2006 Company of BiologistsOocytes regulate follicle growth by secreting paracrine growth factors that act on neighbouring granulosa cells (GCs).

Ageing brings about various biochemical, structural and mechanical alterations within tissues, profoundly impacting cellular behaviour and function. One of the hallmark changes observed with ageing is an increase in cellular microenvironment stiffness, a biomechanical property influenced by intrinsic factors within the cell and extrinsic factors from ...

Novel direct effect of CCR2 receptor on follicle activation process
IntroductionThe regulation of primordial follicle activation is crucial for maintaining ovarian function, the duration of the reproductive phase, and fertility in women; therefore, we propose as our general objective to determine the physiological role ...
