Secondary Amenorrhea and Infertility Due to an Inhibin B Producing Granulosa Cell Tumor of the Ovary. A Rare Case Report and Literature Review

open access: yesMedicina, 2021
Granulosa cell tumor of the ovary (GCT) is a rare ovarian tumor with nonspecific symptoms. Studies reported that GCT are usually secreting estrogens and inhibins, especially inhibin B.

Evidence of a local negative role for cocaine and amphetamine regulated transcript (CART), inhibins and low molecular weight insulin like growth factor binding proteins in regulation of granulosa cell estradiol production during follicular waves in cattle

open access: yesReproductive Biology and Endocrinology, 2006
The ability of ovarian follicles to produce large amounts of estradiol is a hallmark of follicle health status. Estradiol producing capacity is lost in ovarian follicles before morphological signs of atresia.

Ovarian Aging: Role of Pituitary-Ovarian Axis Hormones and ncRNAs in Regulating Ovarian Mitochondrial Activity

open access: yesFrontiers in Endocrinology, 2021
The number of mitochondria in the oocyte along with their functions (e.g., energy production, scavenger activity) decline with age progression. Such multifaceted functions support several processes during oocyte maturation, ranging from energy supply to ...

Gene expression networks underlying ovarian development in wild largemouth bass (Micropterus salmoides). [PDF]

open access: yesPLoS ONE, 2013
Oocyte maturation in fish involves numerous cell signaling cascades that are activated or inhibited during specific stages of oocyte development. The objectives of this study were to characterize molecular pathways and temporal gene expression patterns ...

Physiological roles of activins in the human ovary

open access: yesJournal of Bio-X Research, 2018
. Initially discovered in the pituitary as stimulators of follicle stimulating hormone, activins are homo- or heterodimers of inhibin subunits, which belong to the transforming growth factor-β superfamily.

The Role of TGFβ Signaling in Squamous Cell Cancer: Lessons from Mouse Models

open access: yesJournal of Skin Cancer, 2012
TGFβ1 is a member of a large growth factor family including activins/inhibins and bone morphogenic proteins (BMPs) that have a potent growth regulatory and immunomodulatory functions in normal skin homeostasis, regulation of epidermal stem cells ...

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 ...

Expanded Phenotype Associated With an Intronic PPP1R12A Variant: A Case Report and Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autosomal dominant PPP1R12A‐related genitourinary and/or brain malformation syndrome is a recently described multisystem disorder caused by loss‐of‐function variants in the protein phosphatase 1 regulatory subunit 12a (PPP1R12A) gene. To date, 22 affected individuals have been reported with variable brain malformations and genitourinary ...

Bone turnover across the menopause transition The role of gonadal inhibins

open access: yesAnnals of the New York Academy of Sciences, 2010
Accumulating evidence demonstrates increasing bone turnover and bone loss in women prior to menopause and decreases in serum estradiol levels. Increased follicle‐stimulating hormone levels have been correlated with some of these peri‐menopausal changes ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

open access: yesAnimal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable
