Disruption of Epidermal Growth Factor Receptor but Not EGF Blocks Follicle Activation in Zebrafish Ovary

Frontiers in Cell and Developmental Biology, 2022
Folliculogenesis is controlled by intimate communications between oocytes and surrounding follicle cells. Epidermal growth factor (EGF/Egf) is an important paracrine/autocrine factor in vertebrate ovary, and it is well known for its stimulation of oocyte

Sex Steroid Receptors in Polycystic Ovary Syndrome and Endometriosis: Insights from Laboratory Studies to Clinical Trials

Biomedicines, 2022
Polycystic ovary syndrome (PCOS) and endometriosis are reproductive disorders that may cause infertility. The pathology of both diseases has been suggested to be associated with sex steroid hormone receptors, including oestrogen receptors (ER ...

Gap junctions and ovarian folliculogenesis [PDF]

Reproduction, 2002
Abstract Gap junctions are collections of intercellular membrane channels that allow adjacent cells to share small molecules (< 1 kDa). Gap junction channels are composed of connexins, a homologous family of more than 20 proteins.

RHAMM deficiency disrupts folliculogenesis resulting in female hypofertility [PDF]

, 2015
The postnatal mammalian ovary contains the primary follicles, each comprising an immature oocyte surrounded by a layer of somatic granulosa cells. Oocytes reach meiotic and developmental competence via folliculogenesis. During this process, the granulosa

An Update on In Vitro Folliculogenesis: A New Technique for Post-Cancer Fertility

, 2022
Introduction: Obtaining in vitro mature oocytes from ovarian tissue to preserve women’s fertility is still a challenge. At present, there is a therapeutic deadlock for girls and women who need emergency fertility preservation in case of a high risk

The emerging roles of prohibitins in folliculogenesis [PDF]

Frontiers in Bioscience, 2012
Prohibitins are members of a highly conserved eukaryotic protein family containing the stomatin/prohibitin/flotillin/HflK/C (SPFH) domain (also known as the prohibitin (PHB) domain) found in divergent species from prokaryotes to eukaryotes. Prohibitins are found in unicellular eukaryotes, fungi, plants, animals and humans.

Select aspects of oogenesis and folliculogenesis

, 2013
The processes of oogenesis and folliculogenesis begin very early in foetal life and are continued until the end of the reproductive period. Despite the numerous research conducted, the mechanism which initiates the growth of primary follicles has not ...

Atorvastatin-mediated downregulation of VCAM-1 and XO/UA/caspase 3 signaling averts oxidative damage and apoptosis induced by ovarian ischaemia/reperfusion injury

Redox Report, 2022
Background Oxidative damage is critical in the pathogenesis of ovarian ischaemia/reperfusion (I/R) injury, and statins have been reported to exert antioxidant activity.

Intraovarian Control of Early Folliculogenesis [PDF]

Endocrine Reviews, 2015
Although hormonal regulation of ovarian follicle development has been extensively investigated, most studies concentrate on the development of early antral follicles to the preovulatory stage, leading to the successful use of exogenous FSH for infertility treatment.

Effect of high dose gonadotropin stimulation on follicular atresia through light chain 3B and voltage dependent anion channel 2

Journal of Human Reproductive Sciences, 2022
Background: Follicle development takes place under the control of hormonal and environmental stimuli. It suggested that to improve in vitro fertilisation outcomes in poor responders increasing gonadotropin doses be used.
