Gene expression patterns in anterior pituitary associated with quantitative measure of oestrous behaviour in dairy cows [PDF]

, 2010
Intensive selection for high milk yield in dairy cows has raised production levels substantially but at the cost of reduced fertility, which manifests in different ways including reduced expression of oestrous behaviour.

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

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.

Pituitary hyposignal characteristic of hemochromatosis on MRI

Clinical Case Reports, 2023
Pituitary haemochromatosis is an endocrine disorder caused by the accumulation of iron due to a lack of absorption during haemochromatosis. The characteristic appearance on MRI is a T2 and T2* hyposignal of the anterior pituitary gland without ...

Intercellular Communication in the Anterior Pituitary* [PDF]

Endocrine Reviews, 2000
In addition to hypothalamic and feedback inputs, the secretory cells of the anterior pituitary are influenced by the activity of factors secreted within the gland. The list of putative intrapituitary factors has been expanding steadily over the past decade, although until recently much of the work was limited to descriptions of potential interactions ...
