An Exploration of Non-Coding RNAs in Extracellular Vesicles Delivered by Swine Anterior Pituitary

Frontiers in Genetics, 2021
Extracellular vesicles are lipid bilayer-delimited particles carrying proteins, lipids, and small RNAs. Previous studies have demonstrated that they had regulatory functions both physiologically and pathologically. However, information remains inadequate

Anterior pituitary cell networks

Frontiers in Neuroendocrinology, 2012
Both endocrine and non-endocrine cells of the pituitary gland are organized into structural and functional networks which are formed during embryonic development but which may be modified throughout life. Structural mapping of the various endocrine cell types has highlighted the existence of distinct network motifs and relationships with the ...

Estrogens induce expression of membrane-associated estrogen receptor α isoforms in lactotropes. [PDF]

PLoS ONE, 2012
Estrogens are key to anterior pituitary function, stimulating hormone release and controlling cell fate to achieve pituitary dynamic adaptation to changing physiological conditions. In addition to their classical mechanism of action through intracellular

Clinical features and endoscopic findings of pituicytoma in the sellar region: A case report and review of the literature

Interdisciplinary Neurosurgery, 2019
We report a rare case of pituicytoma occurring in the sellar region resected by endoscopic transsphenoidal surgery (ETSS). We suggest useful indicators for the accurate diagnosis and pitfalls for the surgical procedure.

Oxytocin at physiological concentrations evokes adrenocorticotropin (ACTH) release from corticotrophs by increasing intracellular free calcium mobilized mainly from intracellular stores. Oxytocin displays synergistic or additive effects on ACTH-releasing factor or arginine vasopressin-induced ACTH secretion, respectively [PDF]

, 1992
The potency of oxytocin (OT) in evoking ACTH secretion by isolated, superfused rat adenohypophyseal corticotrophs and its enhancement by CRF and arginine vasopressin (AVP) were analyzed.
