Follicle-stimulating hormone is expressed in ovarian follicles of chickens and promotes ovarian granulosa cell proliferation

Journal of Integrative Agriculture, 2021
Follicle-stimulating hormone (FSH), an important hypothalamic-pituitary-gonadal axis (HPG) hormone, is secreted by the pituitary gland. This study confirms that FSH is expressed in chicken follicles at different stages, and positive FSHβ mRNA signals ...

Stepped vitrification technique for human ovarian tissue cryopreservation [PDF]

, 2019
The advantage of stepped vitrification (SV) is avoiding ice crystal nucleation, while decreasing the toxic effects of high cryoprotectant concentrations. We aimed to test this method for human ovarian tissue cryopreservation.

Effects of antioxidants on viability, plasma membrane integrity and apoptosis in porcine ovarian granulosa cells damaged by bromopropane

Journal of Animal Reproduction and Biotechnology, 2016
The purpose of this study was to examine the effects of taurine and vitamin E on ovarian granulosa cells damaged by bromopropane (BP) in pigs. We evaluated cell viability, plasma membrane integrity (PMI) and apoptotic morphological change in porcine ...

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]

, 1992
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.

lncRNA PVT1/MicroRNA-17-5p/PTEN Axis Regulates Secretion of E2 and P4, Proliferation, and Apoptosis of Ovarian Granulosa Cells in PCOS

Molecular Therapy: Nucleic Acids, 2020
Recently, the roles of microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) were identified in polycystic ovary syndrome (PCOS). In the present study, we investigated the role of the lncRNA PVT1/miR-17-5p/PTEN axis in PCOS ovarian granulosa cells ...

Expression of the neural cell adhesion NCAM in endocrine cells of the ovary [PDF]

, 1991
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.

Elevated SAA1 promotes the development of insulin resistance in ovarian granulosa cells in polycystic ovary syndrome

Reproductive Biology and Endocrinology, 2022
Background Insulin resistance (IR) contributes to ovarian dysfunctions in polycystic ovarian syndrome (PCOS) patients. Serum amyloid A1 (SAA1) is an acute phase protein produced primarily by the liver in response to inflammation.

Neuropeptide Y regulates proliferation and apoptosis in granulosa cells in a follicular stage-dependent manner

Journal of Ovarian Research, 2020
Background The complex regulatory mechanism involved in ovarian follicular development is not completely understood. Neuronal neuropeptide Y (NPY) is involved in the regulation of feeding behavior, energy homeostasis, and reproduction behavior, while its

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

, 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.
