Treatment with the synthetic PPARG ligand pioglitazone ameliorates early ovarian alterations induced by dehydroepiandrosterone in prepubertal rats
(Polish Acad Sciences Inst Pharmacology, 2019-02)
Background: Peroxisome proliferator-activated receptor gamma (PPARG) is a nuclear factor that may act on the early development of ovarian follicles and on follicular steroidogenesis. However, the exact mechanism of PPARG ...
Ovarian differentiation and development in cachara Pseudoplatystoma fasciatum
(2016-07-01)
One thousand five hundred cachara or tiger shovelnose catfish Pseudoplatystoma fasciatum, obtained from induced reproduction, were used to determine the onset of ovarian differentiation and development and to record the ...

(California State University, 2014)
Stress promotes development of ovarian cysts in rats - The possible role of sympathetic nerve activation
(HUMANA PRESS INC, 1998-06)
The ovarian content of neuropeptide Y (NPY) (colocalized with NE) was significantly decreased. These results suggest that NE synthesis and its secretion are increased during this period and correlate with the increase in ...
Effect of long-term injection of dopamine on the ovarian growth of Cherax quadricarinatus juvenile females (Parastacidae, Decapoda).
(Wiley, 2013-10)
The neurotransmitter dopamine (DA) modulates many physiological processes in decapod crustaceans, including reproduction. This study was aimed at evaluating whether the long-term injection of DA affects ovarian growth in ...
Role of nerve growth factor and its TRKA receptor in normal ovarian and epithelial ovarian cancer angiogenesis
(BioMed Central, 2014)
In normal ovarian function a controlled angiogenesis is essential. Several growth factors are involved in this process,
such as the vascular endothelial growth factor (VEGF) and nerve growth factor (NGF). The angiogenesis ...
Halipegus dubius Klein, 1905 (Trematoda, Hemiuridae): a redescription, with notes on the working of the ovarian complex

Effect of estradiol on the expression of angiogenic factors in epithelial ovarian cancer
(Francisco Hernández, Editor, 2017)
Introduction: Ovarian cancer presents a high angiogenesis (formation of new blood vessels) regulated by pro-angiogenic factors, mainly vascular endothelial growth factor (VEGF) and nerve growth factor (NGF). An association ...
Puberty and ovarian function in girls with type 1 diabetes mellitus
(2009)
Insulin is well known for its effects on carbohydrate metabolism, but this hormone also plays an important role in regulating ovarian function. Granulosa, theca and stromal ovarian cells may be affected by insulin deficiency ...
Asymmetric trophallaxis between workers of the stingless bee Melipona quadrifasciata (Apidae, Meliponini)
(2011-12-01)
In several species of social insects, there is a positive relationship between the food exchange that occurs during trophallaxis and the ovarian development of workers, indicating that food transfers are important for the ...
