Enxtraoviarian granulosa cell tumor: a case report [PDF]
Extraovarian granulosa cell tumor (GCT) is a very unusually tumor, assumed to arise from the ectopic gonadal tissue along the embryonal route of the genital ridge.

Extraovarian Granulosa Cell Tumor
A 54-year-old woman was admitted to our hospital complaining of postcoital bleeding. Sonography of the abdomen showed a 8.2 x 8.9 cm-sized solid heterogeneous mass occupying the cul-de-sac, which appeared to be in no way connected with the ovary. On exploratory laparotomy, the tumor mass protruded from the posterolateral retroperitoneum of the pelvic ...

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]
We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.

Expression of the neural cell adhesion NCAM in endocrine cells of the ovary [PDF]
In the adult mammalian ovary morphogenesis and differentiation processes are under hormonal control and, thus, occur in a highly regulated way during the sexual cycle.

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

NR4A1-Driven Granulosa Cell Ferroptosis Contributes to Obesity-Related Ovarian Dysfunction and Metformin-Mediated Ovarian Protection. [PDF]
Schematic illustrating that NR4A1‐driven granulosa cell ferroptosis mediates obesity‐related ovarian dysfunction, while metformin‐mediated ovarian protection is achieved via suppression of the PI3K/AKT–NR4A1 ferroptotic signaling cascade. ABSTRACT Obesity triggers ovarian dysfunction and female infertility accompanied by granulosa cell damage ...

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

Granulosa cell tumor complicated by torsion, rupture and hemoperitoneum [PDF]
Granulosa cell tumor, a sex cord stromal estrogen secreting tumor presents with vaginal bleeding and is seen in all ages. It accounts for <5% of all ovarian neoplasm. We reported a rare case of granulosa cell tumor in a postmenopausal woman undergoing

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

Oocyte-granulosa cell interactions [PDF]
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.
