Transcriptome analysis reveals effects of ethynylestradiol and bisphenol A on multiple endocrine and metabolic pathways in the pituitary and liver of female Atlantic cod (Gadus morhua)

Frontiers in Endocrinology
IntroductionThe pituitary and liver are among the main sites of action of estrogens in fish. Years of research has shown that xenoestrogens can interfere with functions of estrogens. There is however incomplete understanding of xenoestrogen targets genes,

Pulsatile gonadotropin-releasing hormone: clinical applications of a physiologic paradigmEssential Points

F&S Reports, 2023
Gonadotropin-releasing hormone (GnRH) is a fundamental driver of human reproduction. A pulsatile pattern of GnRH secretion is essential to achieve pituitary stimulation, gonadotropin secretion, and normal gonadal function.

Duplicated membrane estrogen receptors in the European sea bass (Dicentrarchus labrax): Phylogeny, expression and regulation throughout the reproductive cycle [PDF]

, 2018
The numerous estrogen functions reported across vertebrates have been classically explained by their binding to specific transcription factors, the nuclear estrogen receptors (ERs).

Impact of 6-month triptorelin formulation on predicted adult height and basal gonadotropin levels in patients with central precocious puberty

Frontiers in Endocrinology, 2023
BackgroundTriptorelin, a long-acting gonadotropin-releasing hormone (GnRH) agonist, is available in 1-, 3-, and 6-month formulations to treat central precocious puberty (CPP).

Responsiveness of bovine cumulus-oocyte-complexes (COC) to porcine and recombinant human FSH, and the effect of COC quality on gonadotropin receptor and Cx43 marker gene mRNAs during maturation in vitro [PDF]

, 2003
Substantially less development to the blastocyst stage occurs in vitro than in vivo and this may be due to deficiencies in oocyte competence. Although a large proportion of bovine oocytes undergo spontaneous nuclear maturation, less is known about ...

The effects of flutamide on the neonatal rat hypothalamic–pituitary–adrenal and gonadal axes in response to hypoxia

Physiological Reports, 2019
Hypoxia is common with preterm birth and may lead to long‐term effects on the adult hypothalamic–pituitary–adrenal (HPA) axis that are sexually dimorphic due to neonatal androgens.

Hormone Receptor Site Maturation in the Secondary Sex Organs of Immature Male and Female Rats [PDF]

, 1976
The effect of a combined dose of pregnant mares\u27 serum (PAAS) and human chor ionic gonadotropin (HCG) on male and female rats 2-25 days old was studied. Groups of animals were given injections for three days, then sacrificed on the fourth day.

Species-specific differences in follicular antral sizes result from diffusion-based limitations on the thickness of the granulosa cell layer

, 2013
The size of mature oocytes is similar across mammalian species, yet the size of ovarian follicles increases with species size, with some ovarian follicles reaching diameters more than 1000-fold the size of the enclosed oocyte.

Oocyte maturation in the toad Rhinella arenarum (Amphibia, Anura): Evidence of cAMP involvement in steroid production and action [PDF]

, 2018
In this work, we describe the participation of the adenylate cyclase/3′-5′-cyclic adenonsine monophosphate (cAMP) pathway in the seasonal follicular secretion of progesterone (P 4 ) and testosterone (T), and its relationship with the maturation of ...

TMC4 localizes to multiple taste cell types in the mouse taste papillae

FEBS Open Bio, EarlyView.
Transmembrane channel‐like 4 (TMC4), a voltage‐dependent chloride channel, plays a critical role in amiloride‐insensitive salty taste transduction. TMC4 is broadly expressed in all mature taste cell types, suggesting a possible involvement of multiple cell types in this pathway.
