Cadmium Mimics Estrogen-Driven Cell Proliferation and Prolactin Secretion from Anterior Pituitary Cells

PLoS ONE, 2013
Cadmium (Cd) is a heavy metal of considerable occupational and environmental concern affecting wildlife and human health. Recent studies indicate that Cd, like other heavy metals, can mimic effects of 17β-estradiol (E2) involving E2 receptor (ER ...

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

Spexin in the European sea bass, Dicentrarchus labrax: Characterization, brain distribution, and interaction with Gnrh and Gnih neurons

Journal of Comparative Neurology, Volume 531, Issue 2, Page 314-335, February 2023., 2023
The main objective of this work was to obtain detailed information on the distribution and localization of the spexin (Spx) system in the sea bass brain. To this purpose, we first identified and characterized the spx1 gene and analyzed its expression in the central nervous system (CNS) of the European sea bass by using quantitative Real‐Time Polymerase

Orexinergic neurons in the hypothalami of an Asiatic lion, an African lion, and a Southeast African cheetah

Journal of Comparative Neurology, Volume 531, Issue 3, Page 366-389, February 2023., 2023
Photomicrograph of orexinergic neurons forming the main orexinergic neuronal cluster in the hypothalamus of a Southeast African cheetah. While showing the standard features of the orexinergic system, the Southeast African cheetah, along with an Asiatic and an African lion, also exhibits specializations in the organization of this system.

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 ...

Expression of Prolactin Receptor mRNA in Lactotrophs and Somatotrophs of the Chicken Anterior Pituitary Gland

The Journal of Poultry Science, 2018
Prolactin (PRL) is a hormone mainly secreted by the anterior pituitary gland. In birds, PRL exerts a variety of physiological functions in target tissues expressing the PRL receptor (PRLR).

Mathematical Modelling of Hypothalamus-Pituitary-Adrenal Axis Dynamics: A Review, a Novel Approach, and Future [PDF]

arXiv, 2023
A novel mathematical model for the hypothalamic pituitary adrenal (HPA) axis is proposed to comprehend the oscillations observed in hormone concentration and potential dysfunction within the HPA axis in stressful situation. This model integrates impact of hippocampal receptors on the secretion of corticotropin-releasing hormone (CRH), an additional ...

Modelling the Establishment of PAR Protein Polarity in the One-Cell C. elegans Embryo [PDF]

Biophys. J. 2008 95: 4512-4522, 2008
At the one-cell stage, the C. elegans embryo becomes polarized along the anterior-posterior axis. The PAR proteins form complementary anterior and posterior domains in a dynamic process driven by cytoskeletal rearrangement. Initially, the PAR proteins are uniformly distributed throughout the embryo.
