Serum gonadal steroid hormones in young schizophrenic patients [PDF]
Psychoneuroendocrinology, 1994 Psychosis is reported to show a later age of onset in women than in men and its nature and course in women may also differ. The purpose of this study was to determine if levels of four steroid hormones at the start of early onset psychosis differ from the levels of other groups of young people and if predicted low levels of estrogen (E2) are a feature ...

Are gonadal steroid hormones involved in disorders of brain aging? [PDF]
Aging Cell, 2003 SummaryHuman aging is associated with a decrease of circulating gonadal steroid hormones. Since these hormones act as trophic factors for neurones and glia, it is possible that the decrease in sex steroid levels may contribute to the increased risk of neurodegenerative disorders with advanced age.

Sexually differentiated regulation of GnRH release by gonadal steroid hormones in sheep [PDF]
Bioscientifica Proceedings, 2019 Exposure of the sheep fetus to testosterone from day 30 to day 90 of a 147 day gestation causes the neurones that control GnRH secretion, the GnRH neuronal network, to become organized in a sex-specific manner. After androgen exposure in utero, GnRH neurones are activated in a sexually differentiated pattern by gonadal steroid hormones.

Sexually Dimorphic Roles of Steroid Hormone Receptor Signaling in Gonadal Tumorigenesis [PDF]
Molecular Endocrinology, 2003 Sex steroids control cellular phenotypes by binding to receptor proteins that in turn regulate downstream gene expression. They are important tropic factors in hormonally responsive tissues and have been implicated in the pathogenesis of both benign proliferations and malignancies at some of these sites.

Thyroid Hormones, Gonadal and Adrenocortical Steroids and the Function of the Islets of Langerhans
Endocrine Reviews, 1984 Thyroid hormones, gonadal and adrenocortical steroids, are glucoregulatory hormones. Thyroid hormones increase the provision of glucose to meet the enhanced energy demands which they impose. Glucose tolerance is decreased, associated with increased hepatic glucose production, although the glucose-raising effects of thyroid hormones are partially offset

General and Comparative Endocrinology, 1993 Plasma and gonadal levels of several gonadal steroids (testosterone, 11-ketotestosterone, androstenedione, 11 beta-hydroxyandrostenedione, 17 beta-estradiol, and estrone) were measured by RIA in the protandrous seabass, Lates calcarifer, throughout an ...

Effect of gonadal steroid hormones on formalin‐induced temporomandibular joint inflammation [PDF]
European Journal of Pain, 2012 AbstractWe have recently demonstrated that gonadal steroid hormones decrease formalin‐induced temporomandibular joint nociception in rats. Given that the attenuation of inflammation is a potential mechanism underlying this antinociceptive effect, we evaluated the effect of gonadal steroid hormones on formalin‐induced temporomandibular joint ...

Genetic variant of luteinizing hormone: impact on gonadal steroid sex hormones in women
Physiological Research, 2001 A common variant of the LHb subunit has a varying prevalence in various ethnic groups. The consequences of the presence of mutated luteinizing hormone (LH) concern borderline alterations in pituitary/gonadal function that could be mediated by an altered action of variant LH on gonadal steroidogenesis.

Regulation of rat luteinizing hormone subunit messenger ribonucleic acids by gonadal steroid hormones. [PDF]
Journal of Clinical Investigation, 1986 Little is known about the hormonal regulation of luteinizing hormone (LH) biosynthesis. We have studied the regulation of LH messenger RNA (mRNA) levels by gonadal-steroid hormones in the rat.

Studies on the Regulation of the Onset of Steroid Hormone Biosynthesis in Fetal Rabbit Gonads* [PDF]
Endocrinology, 1979 Two aspects of the differentiation of the fetal rabbit gonad have been studied. First, the ability of the fetal ovary to synthesize 17β-estradiol from [7-3H]pregnenolone was measured. By day 18 of gestation, the fetal ovary was capable of synthesizing 17β-estradiol from radioactive pregnenolone (5 mol 2 h-1 mg protein-1), thus establishing that from ...
