GGPP-Mediated Protein Geranylgeranylation in Oocyte Is Essential for the Establishment of Oocyte-Granulosa Cell Communication and Primary-Secondary Follicle Transition in Mouse Ovary. [PDF]

open access: yesPLoS Genetics, 2017
Folliculogenesis is a progressive and highly regulated process, which is essential to provide ova for later reproductive life, requires the bidirectional communication between the oocyte and granulosa cells.

Constitutively active transforming growth factor β receptor 1 in the mouse ovary promotes tumorigenesis [PDF]

open access: yes, 2016
Despite the well-established tumor suppressive role of TGFβ proteins, depletion of key TGFβ signaling components in the mouse ovary does not induce a growth advantage.

Effects of angiogenin on granulosa and theca cell function in cattle

open access: yesAnimal, 2017
Angiogenin is a member of the ribonuclease A superfamily of proteins that has been implicated in stimulating angiogenesis but whether angiogenin can directly affect ovarian granulosa or theca cell function is unknown.

Phase II clinical trial of nirogacestat in patients with relapsed ovarian granulosa cell tumours. [PDF]

open access: yesClin Transl Med
Evidence suggests NOTCH activation is among the survival and proliferation pathways interacting with FOXL2 c.402C > G (p.Cys134Trp) mutation in granulosa cell tumours (GCT). This Phase II clinical trial of nirogacestat in GCT achieved its enrolment target in < 1 year and primary analysis within 2 years.

Leptin receptor in the chicken ovary: potential involvement in ovarian dysfunction of ad libitum-fed broiler breeder hens [PDF]

open access: yes, 2004
In hens, the ovarian follicles committed to ovulation are arranged in an ordered follicular hierarchy. In standard broiler breeders hens genetically selected for high growth rate the reproductive function is clearly dysfunctional.

Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]

open access: yes, 2015
cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

Enxtraoviarian granulosa cell tumor: a case report

open access: yesThe Pan African Medical Journal, 2016
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.

Ovarian Gynandroblastoma with a Juvenile Granulosa Cell Tumor Component in a Postmenopausal Woman: A Case Report and Literature Review [PDF]

open access: yesJournal of Pathology and Translational Medicine, 2018
Gynandroblastoma is an extremely rare sex cord-stromal tumor with both female (granulosa cell tumor) and male (Sertoli-Leydig cell tumor) elements. Juvenile granulosa cell tumors are also very rare and are so named because they usually occur in children ...

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.

Regulation of the G2/M Transition in Rodent Oocytes [PDF]

open access: yes, 2010
Regulation of maturation in meiotically competent mammalian oocytes is a complex process involving the carefully coordinated exchange of signals between the somatic and germ cell compartments of the ovarian follicle via paracrine and cell–cell coupling ...
