Chondrichthyan research in South America: Endocrinology overview and research trends over 50 years (1967–2016) compared to the rest of the world
(Academic Press Inc Elsevier Science, 2019-03)
The endocrine system plays a crucial role in regulating the activity of cells and organs among vertebrates, including the class Chondrichthyes. Accordingly, Chondrichthyan endocrinology publications have been steadily ...
Histology and microscopic anatomy of the thyroid gland during the larval development of Pseudis platensis (Anura, Hylidae)
(Veterinary and Human Toxicology, 2019-11-08)
Several hormones regulate anuran larval development, most notably thyroid hormones (THs). In anurans, metamorphosis fails when the thyroid gland is absent or inactivated, resulting in giant tadpoles. Larval gigantism occurs ...
Histo‐morphology of the thyroid gland during the larval development of Pleurodema borellii (Anura, Leptodactylidae)
(Wiley Blackwell Publishing, Inc, 2020-10-11)
The thyroid gland is essential in anurans, since thyroid hormones (TH) are the main regulators of larval development. Its absence or inactivity interrupts development and precludes metamorphosis. Histological changes are ...
Dehydroepiandrosterone treatment attenuates oestrogen-induced pituitary hyperplasia
(BioScientifica, 2002)
The physiological importance of and therapeutic interest in dehydroepiandrosterone (DHEA) has been predominantly in relation to its action as an inhibitor of the promotion and progression of several kinds of tumours, ...
Desensitization of Angiotensin II effect on [Ca2+]i, inositol triphosphate and prolactin in pituitary cells
(American Physiological Society, 2001-12)
Activation of pituitary angiotensin (ANG II) type 1 receptors (AT1) mobilizes intracellular Ca2+, resulting in increased prolactin secretion. We first assessed desensitization of AT1 receptors by testing ANG II-induced ...
Melatonin inhibits glucocorticoid receptor nuclear translocation in mouse thymocytes
(Endocrine Society, 2006-11-11)
The antiapoptotic effect of melatonin (MEL) has been described in several systems. In particular, MEL inhibits glucocorticoid-mediated apoptosis. Our group previously demonstrated that in the thymus, MEL inhibits the release ...
Upregulation of Angiotensin II type 2-receptor expression in estrogen-induced pituitary hyperplasia
(American Physiological Society, 2004-01)
Recent evidence shows that reexpression and upregulation of angiotensin II (ANG II) type 2 (AT2) receptor in adult tissues occur during pathological conditions such as tissue hyperplasia, inflammation, and remodeling. In ...
A carboxy-terminal monoleucine-based motif participates in the basolateral targeting of the Na+/I- symporter
(Endocrine Society, 2019-01)
The Na+/iodide (I2) symporter (NIS), a glycoprotein expressed at the basolateral plasma membrane of thyroid follicular cells, mediates I2 accumulation for thyroid hormonogenesis and radioiodide therapy for differentiated ...
Comparative Stress Response of Black and Gold Howler Monkey (Alouatta caraya) in Urban and Rural Environments of Northern Argentina
(Karger, 2021-09)
The expansion of human populations associated with urbanization results in extensive modification of natural habitats. While many species cannot persist in these highly modified environments, some species adopt new strategies, ...
Thyroid hormone synthesis continues despite biallelic thyroglobulin mutation with cell death
(American Society for Clinical Investigation, 2021-06)
Complete absence of thyroid hormone is incompatible with life in vertebrates. Thyroxine is synthesized within thyroid follicles upon iodination of thyroglobulin conveyed from the endoplasmic reticulum (ER), via the Golgi ...
