Extraovarian granulosa cell tumor

open access: yesIndian Journal of Pathology and Microbiology, 2009
Extraovarian granulosa cell tumor (GCT) is a very uncommon tumor, assumed to arise from the ectopic gonadal tissue along the embryonal route of the genital ridge. One such rare case of extraovarian GCT was encountered in a 58-year-old female who presented with a large intraabdominal lump.

Inhibition of IGFBP4 in Granulosa Cells Improves Reproductive Performance and Maintains Fertility With Age via YAP Signaling

open access: yesAdvanced Science, EarlyView.
IGFBP4 is upregulated in granulosa cells of aged ovaries across monkeys, mice, and humans. It inhibits YAP signaling, thereby suppressing cell proliferation and contributing to follicular dysfunction. Deletion of Igfbp4 in granulosa cells enhances ovulatory output, improves hormone profiles, and reproductive performance in aged female mice, suggesting ...

RHOB Regulates Apoptosis of Granulosa Cells in Muscovy Duck Follicles via Mitochondrial Pathway

open access: yesAnimals
Muscovy ducks (Cairina moschata) exhibit strong nesting tendencies, which result in reduced egg-laying performance. The research team previously identified differential expression of the Ras homolog family member B (RHOB) gene in the ovaries of Muscovy ...

Expression and alternative splicing of the neural cell adhesion molecule NCAM in human granulosa cells during luteinization [PDF]

open access: yes, 1994
Freshly aspirated human granulosa cells from pre-ovulatory follicles and granulosa cells luteinized in culture possess the neural cell adhesion molecule (NCAM) of approximate molecular mass of 140,000 and NCAM mRNA as confirmed by S1-nuclease protection ...

Paternal Sperm Gnas‐ICR Epigenetic Programming Contributes to PPP‐Like Phenotypes in Female Offspring

open access: yesAdvanced Science, EarlyView.
A paternal glucocorticoid–sperm Gnas‐ICR axis is linked to ovarian endocrine programming in female offspring. Paternal preconception caffeine exposure elevates corticosterone, promotes sperm Gnas‐ICR hypermethylation, and is associated with ovarian Gnas upregulation, cAMP/PKA/CREB–StAR activation, enhanced estradiol synthesis, and PPP‐like phenotypes ...

A new isolation and culture method for granulosa cells

open access: yes, 2021
Granulosa cells are the cell population who have an increasing importance in the female genital system and reproduction. Thus, nowadays in vitro studies to address these cells are also gaining importance and attracts researcher's attention.

Spatially Organized Human Ovarian Spheroids Instruct Endometrial Morphogenesis

open access: yesAdvanced Science, EarlyView.
A spatially organized human follicle‐like spheroid (SPHEGaT) composed of granulosa cells (GCs) and stromal‐derived theca‐like cells (TLCs) establishes sustained steroidogenesis in vitro. When co‐cultured with human endometrial organoids (EMOs), estradiol (E2) and progesterone (P4) exchange induces secretory/progesterone‐responsive differentiation ...

The adipokines progranulin and omentin – novel regulators of basic ovarian cell functions

open access: yesReproductive Biology and Endocrinology
The present study aimed to examine the effects of progranulin and omentin on basic ovarian cell functions. For this purpose, we investigated the effects of the addition of progranulin and omentin (0, 0.1, 1, or 10 ng/ml) on the viability, proliferation ...

Hormonal induction of polo-like kinases (Plks) and impact of Plk2 on cell cycle progression in the rat ovary. [PDF]

open access: yesPLoS ONE, 2012
The highly conserved polo-like kinases (Plks) are potent regulators of multiple functions in the cell cycle before and during mitotic cell division. We investigated the expression pattern of Plk genes and their potential role(s) in the rat ovary during ...

Paracrine effects of oocyte secreted factors and stem cell factor on porcine granulosa and theca cells in vitro [PDF]

open access: yes, 2003
Oocyte control of granulosa and theca cell function may be mediated by several growth factors via a local feedback loop(s) between these cell types. This study examined both the role of oocyte-secreted factors on granulosa and thecal cells, cultured ...
