Ovarian activity regulation by anti-Müllerian hormone in early stages of human female life, an overview

open access: yesAnthropological Review, 2018
The present study aimed at describing the anti-Müllerian hormone (AMH), with special focus on molecular background for ovarian activity, in particular the role AMH plays in sex determination and gonadogenesis process in early stages of prenatal life and ...

FMR1 expression in human granulosa cells increases with exon 1 CGG repeat length depending on ovarian reserve [PDF]

open access: yes, 2018
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.

Transcription Factor TCF12‐Mediated Maternal Gene Expressions in Mouse Oocyte Are Prerequisites of Successful Fertilisation and Zygotic Genome Activation

open access: yesCell Proliferation, EarlyView.
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 ...

Immunostaining of P450c17, Aromatase and Oestrogen Receptor Alpha in Germ and Somatic Cells During Gonadal Development in Greater Rhea

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
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

open access: yesCurrent Issues in Molecular Biology
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 ...

Decreased PTGES2 Farnesylation in Granulosa Cells Compromises PGE2‐Dependent Cumulus Expansion and Oocyte Maturation During Ovarian Aging

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
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.

Mechanopharmacology of cellular microenvironment stiffness: Therapeutic strategies for age‐related diseases

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 4, Page 945-956, February 2026.
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

open access: yesFrontiers in Endocrinology
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 ...
