Aquaporin-8 transports hydrogen peroxide to regulate granulosa cell autophagy

open access: yesFrontiers in Cell and Developmental Biology, 2022
Aquaporin-8 (AQP8), a member of the aquaporin family, is strongly expressed in follicular granulosa cells, which could affect the hormone secretion level in females.

Unicystic Granulosa Cell Tumor [PDF]

open access: yesJournal of Pathology and Translational Medicine, 2015
Granulosa cell tumors are the most frequent sex cord stromal tumor and account for approximately 5% of all primary ovarian tumors. About 5% occur before puberty and 40% occur in the menopausal age group; however, these tumors have an indolent biological behavior [1].

Effect of oxytocin on free intracellular Ca2+ levels and progesterone release by human granulosa-lutein cells [PDF]

open access: yes, 1993
Oxytocin and its receptor are found in the corpus luteum in a variety of species, including the human. In the present study we used fura-2 microfluorimetry to investigate whether activation of the oxytocin receptor of cultured human granulosa-lutein ...

Concerted action of human chorionic gonadotropin and norepinephrine on intracellular-free calcium in human granulosa-lutein cells [PDF]

open access: yes, 1993
Luteal cells are known to possess receptors for LH/hCG and receptors of the beta-adrenergic type. Interactions of specific agonists with either receptor lead to the activation of adenylate cyclase and subsequently to an increase of cAMP.

ERK1/2-SOX9/FOXL2 axis regulates ovarian steroidogenesis and favors the follicular–luteal transition

open access: yesLife Science Alliance, 2023
ERK1/2 negatively regulates estradiol synthesis while positively regulating progesterone production in ovarian granulosa cells via the ERK1/2-SOX9/FOXL2 axis. Estradiol and progesterone are the primary sex steroids produced by the ovary. Upon luteinizing

The Cultivation of Human Granulosa Cells [PDF]

open access: yesActa Medica (Hradec Kralove, Czech Republic), 2008
The major functions of granulosa cells (GCs) include the production of steroids, as well as a myriad of growth factors to interact with the oocyte during its development within the ovarian follicle. Also FSH stimulates GCs to convert androgens (coming from the thecal cells) to estradiol by aromatase.

Stem cells in the ovary [PDF]

open access: yes, 2009
For decades, scientists have thought that female mammals are born with a lifetime supply of oocytes in the ovary, irreversibly destined to decline after birth.

Changes in expression of TNF alpha and its receptors mRNAs in oocytes and granulosa cells in mice with experimental immune ovarian failure [PDF]

open access: yes, 2014
Purpose: To investigate the expression of TNF- α and its receptors (types I and II) at mRNA level in oocytes and granulose cells as well as to study effect of TNF-α on follicular cell death in mice with experimental immune ovarian failure induced by ...

Induction of Ski Protein Expression upon Luteinization in Rat Granulosa Cells [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2012
Ski protein is implicated in proliferation/differentiation in a variety of cells. We had previously reported that Ski protein is present in granulosa cells of atretic follicles, but not in preovulatory follicles, suggesting that Ski has a role in ...

Oocyte-granulosa cell interactions [PDF]

open access: yesHuman Reproduction Update, 2000
In the past, different protocols of ovulation induction, aimed to overcome problems of anovulatory infertility in humans, have been developed during IVF programmes. However, administration of exogenous hormones may cause severe health problems, e.g. ovarian hyperstimulation syndrome.
