Angiogenesis in pituitary adenomas: human studies and new mutant mouse models
(Hindawi Publishing Corporation, 2014-11-18)
The role of angiogenesis in pituitary tumor development has been questioned, as pituitary tumors have been usually found to be less vascularized than the normal pituitary tissue. Nevertheless, a significantly higher degree ...
Morphological and immunohistochemical comparison of the pituitary gland between a tropical paracheirodon axelrodi and a subtropical aphyocharax anisitsi characids (Characiformes: Characidae)
(2020-01-01)
Cardinal tetra Paracheirodon axelrodi and bloodfin tetra Aphyocharax anisitsi are two species of characids with high trade value as ornamental fish in South America. Although both species inhabit middle water layers, ...
Rathke’s cleft cyst infections and pituitary abscesses: case series and review of the literature
(Springer, 2021)
Purpose: Pituitary abscesses (PAs) are a rare clinical entity which may arise from normal pituitary tissue or underlying lesions within the gland. Rathke’s cleft cysts (RCCs) are not commonly associated with the development ...
Anterior pituitary gland synthesises dopamine from l-3,4-dihydroxyphenylalanine (l-dopa)
(Wiley & Sons, 2020-06)
Prolactin (PRL) is a hormone principally secreted by lactotrophs of the anterior pituitary gland. Although the synthesis and exocytosis of this hormone are mainly under the regulation of hypothalamic dopamine (DA), the ...
Rathke’s cleft-like cysts arise from Isl1 deletion in murine pituitary progenitors
(American Society for Clinical Investigation, 2020-08)
The transcription factor ISL1 is expressed in pituitary gland stem cells and the thyrotrope and gonadotrope lineages. Pituitary-specific Isl1 deletion causes hypopituitarism with increased stem cell apoptosis, reduced ...
In vivo xenoestrogenic actions of cadmium and arsenic in anterior pituitary and uterus
(BioScientifica, 2016-07-01)
Cadmium (Cd) and arsenic (iAs) are toxic metals ubiquitously present in the environment. Both pollutants exert nonmonotonic dose-responses, being mostly cytotoxic at high concentrations but mimicking estrogen (E2) effects ...

(Wiley-liss, div John Wiley & Sons Inc., 2010-02)
Lactotrophs in pituitary pars distalis (PD) of viscacha were studied by immunohistochemistry and morphometric analysis in the following groups: 1) adult males throughout the reproductive cycle (reproductive, gonadal ...
