Cholesterol transport and steroidogenesis by the corpus luteum
(2003)
The synthesis of progesterone by the corpus luteum is essential for the establishment and maintenance of early pregnancy. Regulation of luteal steroidogenesis can be broken down into three major events; luteinization (i.e., ...
Rapid actions of the neurosteroid allopregnanolone on ovarian and hypothalamic steroidogenesis: Central and peripheral modulation
(Wiley Blackwell Publishing, Inc, 2020-01)
The present study aimed to determine whether an i.c.v. administration of allopregnanolone (ALLO) rapidly modifies the hypothalamic and ovarian 3β‐hydroxysteroid dehydrogenase (3β‐HSD) enzymatic activity and gene expression ...
Prolactin is a strong candidate for the regulation of luteal steroidogenesis in vizcachas (Lagostomus maximus)
(Hindawi Publishing Corporation, 2018-06)
Prolactin (PRL) is essential for the maintenance of the corpora lutea and the production of progesterone (P4) during gestation of mice and rats, which makes it a key factor for their successful reproduction. Unlike these ...
Effects of guanethidine-induced sympathectomy on the spermatogenic and steroidogenic testicular functions of prepubertal to mature rats
(Blackwell Wissenschafts Verlag Gmbh, 1996-03-01)
Selective chemical sympathectomy of the internal genital organs of prepubertal to mature male Wistar rats was performed by chronic treatment with low doses of guanethidine. Sympathetic denervation caused an increase in ...

(Blackwell Wissenschafts Verlag Gmbh, 1996-03-01)

Recent progress in understanding aldosterone secretion
(1997)
1. The synthesis and secretion of aldosterone in the adrenal zona glomerulosa in physiologic conditions is controlled by adrenocorticotropin (ACTH), angiotensin II (AII), and extracellular (K+). 2. ACTH effects on aldosterone ...
Is ouabain produced by the adrenal gland?
(1998)
Ouabain or a related stereoisomer, termed endogenous ouabain, has been identified in adrenal cortex tissue and culture medium from adrenocortical cells.Angiotensin II and adrenocorticotropin, the main activators of aldosterone ...
Expression and function of OXE receptor, an eicosanoid receptor, in steroidogenic cells
(Elsevier Ireland, 2013-05)
Hormonal regulation of steroidogenesis involves arachidonic acid (AA) metabolism through the 5-lipoxygenase pathway. One of the products, 5-hydroperoxy-eicosatetraenoic acid (5-HpETE), acts as a modulator of the activity ...
MAPK phosphatase-1 (MKP-1) expression is up-regulated by hCG/cAMP and modulates steroidogenesis in MA-10 Leydig cells
(Oxford University Press, 2011-07)
MAP kinases (MAPKs), such as ERK1/2, exert profound effects on a variety of physiological processes. In steroidogenic cells, ERK1/2 are involved in the expression and activation of steroidogenic acute regulatory protein, ...
