Growth factors and steroidogenesis in the bovine placenta
(Belo Horizonte, 2008)
The control of placental hormone biosynthesis is critical during gestation, since their coordinated action is essential for the normal progress of pregnancy. Hormonal synthesis regulation in placenta is still not elucidated ...
Impaired insulin signaling pathways affect ovarian steroidogenesis in cows with COD
(Elsevier Science, 2018-05)
Cystic ovarian disease (COD) represents an important cause of infertility in dairy cattle and is associated with multiple physiological disorders. Steroidogenesis, which is necessary to ensure normal ovarian functions, ...
Effects of heme oxygenase isozymes on Leydig cells steroidogenesis
(BioScientifica, 2009-10)
In the present study, we demonstrate the expression of heme oxygenase (HO) isozymes, HO-1 and HO-2 (listed as HMOX1 and HMOX2 in the MGI Database), in MA-10 Leydig tumor cells and its effect on steroidogenesis. The well-known ...
Histamine inhibits adrenocortical cell proliferation but does not affect steroidogenesis.
(Bioscientifica, 2014-03-07)
Histamine (HA) is a neurotransmitter synthesized in most mammalian tissues exclusively by histidine decarboxylase enzyme. Among the plethora of actions mediated by HA, the modulatory effects on steroidogenesis and proliferation ...
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., ...

A single dose of allopregnanolone affects rat ovarian morphology and steroidogenesis
(BioScientifica, 2016-10)
Allopregnanolone, a progesterone metabolite, is one of the best characterized neurosteroids. In a dose that mimics serum levels during stress, allopregnanolone inhibits sexual receptivity and ovulation and induces a decrease ...
Participation of the extrinsic cholinergic innervation in the action of nitric oxide on the ovarian steroidogenesis in the first proestrous in rats
(Academic Press Inc Elsevier Science, 2016-09)
An ex-vivo Coeliac Ganglion-Superior Ovarian Nerve-Ovary (CG-SON-O) system and an ovary without peripheral neural influence from virgin rats in the first proestrous were used to test whether ovarian extrinsic innervation ...
